Description

201235395 六、發明說明: 【發明所屬之技術領域】 本發明係關於半導體密封塡充用薄膜狀樹脂組成物、 半導體裝置之製造方法及半導體裝置。 ' 【先前技術】 近年來,隨著電子設備之小型化、高功能化之進展, 對半導體裝置要求小型化、薄型化及電特性之提升(對高 頻傳輸之對應等)。伴隨於此,而自以往之以線黏合( wire bonding)將半導體晶片安裝於基板上之方式,開始 朝於半導體晶片上形成稱爲突出物之導電性突起電極且與 基板電極直接連接之覆晶連接方式進行。 至於在半導體晶片上形成之突出物雖係使用以焊料或 金構成之突出物,但爲對應近年來之微細連接化,已變成 使用在銅柱之前端形成焊料層或錫層而成之構造之突出物 〇 又,爲了高信賴性化,而要求利用金屬接合而連接, 不僅採用使用了焊料突出物的焊料接合或利用於銅柱之前 端形成有焊料層或錫層之構造之突出物之金屬接合,於使 ' 用金突出物時,亦已採用於基板電極側形成焊料層或錫層 ,而進行金屬接合之連接方法。 再者,覆晶連接方式由於會有源自半導體晶片與基板 之熱膨脹係數差之熱應力集中於連接部而破壞連接部之虞 • ,故爲了分散該熱應力並提高連接信賴性,有必要以樹脂 -5- 201235395 密封塡充半導體晶片與基板間之空隙。一般’利用樹脂密 封塡充係採用使用焊料等將半導體晶片與基板連接後,利 用毛細管現象於空隙中注入液狀密封樹脂之方式。 於使晶片與基板連接之際,爲使焊料等之表面氧化膜 還原除去而使金屬接合變容易,而使用由松香或有機酸等 所成之助焊劑。此處,若殘留助焊劑殘渣,則注入液狀樹 脂時會造成稱爲孔隙之氣泡發生,或會因酸成分會發生配 線腐蝕,使連接信賴性降低,故必須進行洗淨殘渣之步驟 。然而,近年來,隨著連接間隙之窄間距化,半導體晶片 與基板間之空隙變得狹小,故有助焊劑殘渣之洗淨變困難 之情況。再者,於半導體晶片與基板間之狹小空隙中注入 液狀樹脂需要長時間,而有生產性降低之問題。 爲解決此種液狀密封樹脂之問題,已提出有使用具備 將焊料等之表面之氧化膜還原去除之性質(助焊劑活性) 之密封樹脂’對基板供給密封樹脂後,使半導體晶片與基 板連接之同時’以樹脂密封塡充半導體晶片及基板間之空 隙’而可省略助焊劑殘渣之洗淨之稱爲先供給方式之連接 方法(例如參考專利文獻1〜5 )。 [先前技術文獻] [專利文獻] [專利文獻1]日本特開2006-143795號公報 [專利文獻2]日本特開2007-107006號公報 [專利文獻3]日本特開2008-294382號公報 [專利文獻4]日本特開2009_239138號公報 201235395 [專利文獻5]日本特開200 5 -2 8 73 4號公報 【發明內容】 [發明欲解決之課題] '然而,以往之先供給方式爲了減低密封樹脂之熱膨脹 係數而調配之塡料會夾在突出物與基板電極之間而發生稱 爲凹陷(trapping )之連接不良,而引起導電不良,有以 夾入之塡料爲起點而於突出物或基板電極上產生龜裂而使 連接信賴性下降之問題。 本發明之目的係提供一種作爲先供給方式用之密封樹 脂使用時,可充分抑制凹陷之產生,且獲得具有良好導電 性及連接信賴性之半導體裝置之半導體密封塡充用薄膜狀 樹脂組成物,以及使用其之半導體裝置及其製造方法。 [解決課題之手段] 本發明係提供一種半導體密封塡充用薄膜狀樹脂組成 物’其係具備··由含有熱硬化性樹脂及塡料之第1樹脂組 成物所構成的第1層、與含有助焊劑之第2樹脂組成物所 構成的第2層’且相對於前述第2樹脂組成物總量之前述 第2樹脂組成物中的塡料之質量比率,比相對於前述第1 樹脂組成物總量之前述第1樹脂組成物中的塡料之質量比 率更小。 依據本發明,可防止在突出物與基板電極之間夾入塡 ' 料,可形成良好之連接部。亦即,依據本發明之半導體密 201235395 封塡充用薄膜狀樹脂組成物,可充分抑制 凹陷之產生,且可獲得具有良好導電性及 導體裝置。 又,依據本發明之半導體密封塡充用 物,以連接半導體晶片與基板時之加熱加 成物硬化,使硬化後之第1樹脂組成物補 電極之連接部。據此,在連接結束後之冷 體晶片與基板之熱膨脹係數差所造成之熱 部及產生龜裂等連接不良之生成可充分受 依據此種半導體密封塡充用薄膜狀樹脂組 接信賴性更優異之半導體裝置。 本發明之半導體密封塡充用薄膜狀樹 上述第2樹脂組成物進一步含有熱可塑性 該半導體密封塡充用薄膜狀樹脂組成 組成物構成之第2層之表面黏附力低。因 半導體製造方法中,具有於將貼附有半導 膜狀樹脂組成物之半導體晶圓單粒化成半 止所產生之切削層附著於第2層表面上之 本發明另提供半導體裝置之製造方法 形成有複數個突出物之突出物形成面之半 有設有複數個電極之電極面的基板之半導 法,其特徵在於具備:將如上述本發明之 用薄膜狀樹脂組成物,以使前述第2層相 配置於前述基板側之方式,貼附於前述基 先供給方式中之 連接信賴性之半 薄膜狀樹脂組成 壓使第1樹脂組 強突出物與基板 卻過程中,半導 應力集中於連接 到抑制。亦即,

含有助焊劑之第2樹脂組成物所構成的第2層’且相對於 第2樹脂組成物總量之第2樹脂組成物中的塡料之質量比 率,比相對於第1樹脂組成物總量之第1樹脂組成物中的 塡料之質量比率更小者。 此處,第2樹脂組成物可含有塡料亦可不含。亦即, 「相對於第2樹脂組成物總量之第2樹脂組成物中的塡料 之質量比率」亦可爲〇質量%。 依據本實施形態之半導體密封塡充用薄膜狀樹脂組成 物,可充分抑制先供給方式中凹陷之產生。爲此,藉由使 用本實施形態之半導體密封塡充用薄膜狀樹脂組成物,可 獲得具有良好導電性及連接信賴性之半導體裝置。 (第1層) 第1層爲由含有塡料之第1樹脂組成物所構成之層。 至於塡料較好使用無機塡料。使用無機塡料時,由於 第1樹脂組成物(或其硬化物)之熱膨脹係數更低,故使 利用半導體密封塡充用薄膜狀樹脂組成物密封塡充之半導 體裝置之連接信賴性變更良好。 至於無機塡料列舉爲玻璃、二氧化矽(Silica )、氧 化銘(alumina)、氧化欽(titania)、氧化鎂(magnesia )、碳黑、雲母、硫酸鋇等。該等可單獨使用或混合兩種 -11 - 201235395 以上使用。 又,作爲無機塡料亦可使用含兩種以上金屬 化物(並非單純混合兩種以上之金屬氧化物者, 氧化物彼此經化學鍵結成爲無法分離之狀態者) 機塡料列舉爲例如含有由矽、鈦、鋁、硼及鎂所 選出之至少兩種元素之複合氧化物。更具體而言 例如二氧化砂與氧化鈦之複合氧化物、由二氧化 鋁構成之複合氧化物、由氧化硼與氧化鋁所構成 化物' 由二氧化矽與氧化鋁及氧化鎂所構成之複 等。該等複合氧化物可單獨使用或混合兩種以上 可與上述之無機塡料混合使用。 又,本實施形態中,爲了孔隙抑制效果或應 亦可組合孔隙無機塡料與有機塡料作爲塡料使用 有機塡料列舉爲例如由丙烯酸樹脂、聚矽氧 二烯橡膠、聚酯、聚胺基甲酸酯、聚乙烯縮丁醛 酸酯、聚甲基丙烯酸甲酯、丙烯酸橡膠、聚苯乙 、SBR、聚矽氧改質之樹脂等樹脂成分所構成之每 至於有機塡料較好爲含有分子量100萬以上 有機微粒子或具有三次元交聯構造之有機微粒子 微粒子對樹脂組成物之分散性高。且,含有該有 之薄膜狀樹脂組成物之接著性與硬化後之應力緩 異。又,此處所謂「具有三次元交聯構造」係表 機微粒子之樹脂之聚合物鏈具有三次元網目構造 該構造之樹脂係藉由例如具有複數個反應點之聚 之複合氧 而是金屬 。該種無 組成群組 ,列舉爲 矽與氧化 之複合氧 合氧化物 使用,亦 力緩和, 〇 樹脂、丁 、聚丙烯 烯、NBR I料。 之樹脂之 。該有機 機微粒子 和性更優 示構成有 ,且具有 合物以具 -12- 201235395 有兩個以上之可與該反應點鍵結之官能基之交聯劑處理而 獲得。含有分子量爲1〇〇萬以上之樹脂之有機微粒子及具 有三次元交聯構造之有機微粒子對任何溶劑之溶解性均低 之方面而言係較佳。對溶劑之溶解性低之該等有機微粒子 可更顯著地獲得上述效果。另外,就更顯著地獲得上述效 果之觀點而言,上述有機微粒子較好爲由(甲基)丙烯酸 烷酯-聚矽氧共聚物、聚矽氧-(甲基)丙烯酸共聚物或該 等之複合物所構成之有機微粒子。 至於有機塡料可使用具有蕊殻(core-shell)型構造, 且蕊層與殻層中之組成不同之有機微粒子。蕊殻型有機微 粒子具體而言列舉爲以聚矽氧-丙烯酸橡膠爲蕊而接枝丙 烯酸樹脂之粒子,以丁二烯橡膠爲蕊而接枝丙烯酸樹脂或 苯乙烯樹脂之粒子等。 使用含有分子量爲1〇〇萬以上之樹脂之有機微粒子或 具有三次元交聯構造之有機微粒子作爲有機塡料時,由於 對有機溶劑之溶解性低,故容易以維持粒子形狀之狀態直 接含於薄膜狀樹脂組成物中。據此,有機微粒子在薄膜狀 樹脂組成物中可分散成島狀,可進一步提高硬化後之薄膜 狀樹脂組成物之強度。 瑱料之形狀並無特別限制,列舉爲破碎狀、針狀、鱗 片狀、球狀等。該等中,塡料之形狀較好爲球狀。球狀之 塡料由於在樹脂組成物中之分散性良好,故可防止塡料集 中於樹脂組成物之特定部位而容易夾入突出物與基板電極 之間,可獲得連接信賴性更優異之半導體裝置。又,塡料 -13- 201235395 爲球狀時,會有樹脂組成物之黏度控制變容易之傾向。又 ,此處所謂球狀未必一定爲真球,亦可爲略球狀。 塡料之尺寸只要是比覆晶連接時之半導體晶片與基板 間之空隙小者即可。塡料之平均粒徑就可提高塡充密度, 使樹脂組成物之黏度控制變容易之觀點而言,較好爲 1 Ομιη以下,更好爲5μιη以下,又更好爲3μηι以下。又, 塡料之平均粒徑之下限値並無特別限制,例如可使用平均 粒徑爲0.01 μηι以上之塡料。又,爲了更顯著地獲得本實 施形態之半導體密封塡充用薄膜狀樹脂組成物中之效果( 良好之導電性及連接信賴性),塡料之平均粒徑可設爲 0.05〜0·9μιη,亦可爲 0.1~0.8μηι。 又,此處所謂平均粒徑爲可利用雷射光繞射法之粒度 分布測定裝置以中値直徑求得者。所謂中値直徑係表示個 數基準之粒度分布中之累積率成爲50%之粒徑(D50)之 値。 相對於第1樹脂組成物總量之第1樹脂組成物中之塡 料的質量比率,就使第1樹脂組成物(或其硬化物)之熱 膨脹係數更低之觀點而言,較好爲20質量%以上,就進一 步提高第1樹脂組成物(或其硬化物)之機械強度之觀點 而言,更好爲3 0質量%以上,就進一步降低第1樹脂組成 物(或其硬化物)之吸水率之觀點而言,又更好爲40質 量%以上。 相對於第1樹脂組成物總量之第1樹脂組成物中之塡 料的質量比率之上限値並無特別限制,例如可設爲70質 -14- 201235395 量%以下,亦可設爲60質量%以下,超過70質量%時第1 樹脂組成物變脆,有操作性降低之傾向。 有機塡料與無機塡料倂用時,有機塡料之質量比率相 對於第1樹脂組成物宜爲1~10質量%。爲1質量%以上時 ,可顯著獲得由有機塡料所致之孔隙抑制效果或應力緩和 效果,爲1 〇質量%以下時,樹脂組成物之增黏獲得抑制, 可減低薄膜狀樹脂組成物表面之凹凸,更抑制孔隙之發生 ,且更提高接著性。 第1樹脂組成物較好含有熱硬化性樹脂。 藉此,在連接半導體晶片與基板時之加熱加壓下使第 1樹脂組成物硬化,且經硬化之第1樹脂組成物可補強突 出物與基板電極之連接部。因此,連接完成後之冷卻過程 中’可充分抑制起因半導體晶片與基板之熱膨脹係數差異 所致之熱應力集中於連接部而造成龜裂等連接不良。亦即 ’藉由使第1樹脂組成物含有熱硬化性樹脂,所得之半導 體裝置之連接信賴性會變得更優異。 至於熱硬化性樹脂列舉爲酚樹脂、氰酸酯樹脂、苯并 環丁烯樹脂、丙烯酸酯樹脂、甲基丙烯酸酯樹脂、環氧樹 脂等。基於耐熱性優異及使作業性變良好,第一樹脂組成 物較好含有環氧樹脂作爲熱硬化性樹脂。 例如使用2官能基以上之環氧樹脂(分子中具有2個 以上環氧基之環氧樹脂)作爲環氧樹脂。該環氧樹脂可使

他各種多官能基環氧樹脂等。 該等環氧樹脂中,就可容易地實現樹脂組成物之低黏 度化、降低樹脂組成物(或其硬化物)之吸水率且更難產 生尺寸變化'進一步提高樹脂組成物(或其硬化物)之耐 熱性等之觀點而言,較好使用雙酚A型環氧樹脂、雙酚F 型環氧樹脂、含有萘骨架之多官能基環氧樹脂、含有二環 戊二烯之多官能基環氧樹脂、含有三苯基甲烷骨架之多官 能基環氧樹脂等。 至於環氧樹脂之性狀在25 t下爲液狀或爲固態均無妨 。且,該等環氧樹脂可單獨使用或混合兩種以上使用。 第1樹脂組成物可進而含有硬化劑。硬化劑可依據熱 硬化性樹脂之種類適當選擇。例如,第1樹脂組成物含有 環氧樹脂作爲熱硬化性樹脂時,可使用咪唑類、酸酐類、 胺類、酚類、聯胺類、聚硫醇類、路易斯酸-胺錯合物等 作爲硬化劑。該等硬化劑中,就可容易地實現樹脂組成物 之低黏度化、儲存安定性優異、更提高樹脂組成物之硬化 物之耐熱性等觀點而言,較好使用咪唑類、酸酐類、胺類 、酚類。且,以聚胺基甲酸酯系、聚酯系之高分子物質等 被覆並經微膠囊化者作爲硬化劑由於可延長可使用時間故 -16- 201235395 較佳。 上述咪唑類列舉爲2 -甲基咪唑、2 -十一烷基咪唑、2-苯基咪唑、2-乙基-4-甲基咪唑、2-苯基-4-甲基咪唑、1-苄 基-2-甲基咪唑、卜苄基-2-苯基咪唑、1-氰乙基-2 -甲基咪

第2層爲由含有助焊劑之第2樹脂組成物構成之層。 第2樹脂組成物中,爲了還原去除焊料等之金屬之表面氧 化膜,以金屬接合形成良好之連接度,而調配助焊劑爲必 須成分。 又,相對於第2樹脂組成物總量之第2樹脂組成物中 之塡料的質量比率,比相對於第1樹脂組成物總量之第1 樹脂組成物中之塡料的質量比更小。藉由具有該構成,而 充分抑制先供給方式中之凹陷發生。又,第2樹脂組成物 可含有塡料亦可不含。

後述之半導體裝置之製造方法中貼合於半導體晶圓上時, 可透過第2層辨識突出物前端部,可獲得使切晶時之位置 對準或連接時與基板之位置對準變容易之效果。又,爲了 使該突出物前端部之辨識成爲可能,第2層之光透過率對 於5 5 5nm之可見光宜爲10%以上,更好爲20%以上,又更 好爲40%以上。又,光透過率對於5 50nm之可見光可爲 95%以下,亦可爲90%以下。 第2樹脂組成物較好含有熱可塑性樹脂。第2樹脂組 成物含有熱可塑性樹脂時,會有第2層之表面黏附力變低 之傾向。因此,例如於後述之半導體之製造方法中,可發 揮防止將貼附有半導體密封塡充用薄膜狀樹脂組成物之半 導體晶圓單粒化成半導體晶片時產生之切削層附著於第2 層表面之效果。 就更顯著獲得該效果之觀點而言,第2樹脂組成物中 之熱可塑性樹脂之含量,以第2樹脂組成物之總量爲基準

,更好爲0.7倍以下。第2層厚度之下限並無特別限制, 可爲第1層厚度之〇.〇5倍以上,亦可爲第1層厚度之0.1 倍以上。 半導體密封用薄膜狀樹脂組成物之厚度可依據用以塡 充半導體晶片與基板之間之空隙所需之樹脂量而適當設定 。例如,半導體密封塡充用薄膜狀樹脂組成物之厚度較好 爲連接前之突出物之高度的0.5〜1.5倍,更好爲0.6〜1.3 倍,又更好爲〇.7~1.2倍。厚度爲突出物之高度的0.5倍

本實施形態之半導體裝置之製造方法具備準備具有電 極之基板、形成突出物之半導體晶片、與貼合於基板或半 導體晶片上之半導體密封塡充用薄膜狀樹脂組成物之準備 步驟,及使基板之電極與半導體晶片之突出物電連接之連 接步驟。 此處,基板之電極及半導體晶片之突出物之至少一表 面上存在焊料或錫。因此,如專利文獻5中所記載之方法 ,作爲防止突出物與基板電極之間之凹陷,若突出物前端 自樹脂組成物露出時,露出之焊料或錫會形成氧化膜而有 導致連接不良之虞。相對於此,依據本實施形態之半導體 裝置之製造方法,由於基板電極與突出物之接合部係位在 第.2層內,故可防止因焊料或錫之氧化膜造成之連接不良 ,且可充分抑制凹陷。 且,由於基板之電極及半導體晶片之突出物之至少一 -32- 201235395 表面上存在焊料或錫’故基板之電極與半導體晶片之突出 物之電連接通常會藉由焊料或錫之金屬接合完成。亦即, 藉由焊料或錫利用連接時之加熱而熔融,使基板之電極與 半導體晶片之突出物透過焊料或錫而接合。藉由進行該金 屬接合’而獲得優異之導電性及連接信賴性。 至於半導體晶片,可使用在複數個電極上形成有複數 個突出物之半導體晶片。半導體晶片之材質並無特別限制 ’可使用矽、鍺等元素半導體;砷化鎵、磷化銦等化合物 半導體等之各種半導體》 至於半導體晶片上形成之突出物列舉爲例如銅突出物 、金突出物、焊料突出物、銅柱之前端形成有焊料或錫層 之構造之突出物等。 焊料可使用Sn-37Pb (熔點183°C).,但考慮對環境 之影響,較好使用Sn-3.5Ag (熔點221°C ) 、Sn-2.5Ag- 0.5Cu-lBi (熔點 214°C) 、Sn-0.7Cu (熔點 227°C) 、Sn-3Ag-0.5Cu (熔點 217°C ) 、Sn-92Zn (熔點 198°C )等之無 鉛銲料。又,就對應於微細連接化之觀點而言,較好爲在 銅柱前端形成焊料或錫層之構造之突出物。 基板具有設置有複數個電極之電極面。至於基板可使 用一般之電路基板,亦可使用不具有突出物之半導體晶片 〇 至於電路基板可使用餽刻去除於玻璃環氧樹脂、聚醯 亞胺、聚酯、陶磁等絕緣基板表面上形成之銅等金屬層之 不需要部位而形成含電極之配線圖型者;藉由於絕緣基板 -33- 201235395 表面上鍍銅等而形成含電極之配線圖型者;將導電性物質 印刷於絕緣基板表面而形成含電極之配線圖型者等。 基板之電極表面上較好形成由金層、焊料層、錫層及 防銹皮膜層選出之至少一種表面處理層。金屬及錫層可藉 由無電解電鍍或電解電鍍形成。另外,焊料層可藉由電鍍 形成,亦可藉由印刷塗佈焊料糊料並經加熱熔融之方法, 亦可藉由將微細之焊料粒子配置於配線圖型上並經加熱熔 融之方法形成。 防銹皮膜層亦稱爲預助焊,係藉由將基板浸漬於專用 之藥液中,去除以銅等形成之配線圖型表面之氧化膜,同 時藉由於該表面上形成由有機成分所構成之防銹皮膜而設 置。該種防銹皮膜層由於可確保對焊料或錫之良好潤濕性 ,同時容易對應於微細連接化故較佳。 爲進行上述之金屬接合,半導體晶片之突出物爲銅突 出物、金突出物等之表面上不具有焊料或錫之突出物時, 選擇表面上形成有焊料層或錫層之電極作爲基板之電極。 另外,基板之電極表面上不存在焊料或錫時,半導體晶片 之突出物係選擇焊料突出物、銅柱之前端形成焊料或錫層 之構造之突出物等。 至於準備步驟,列舉爲例如準備基板、貼附於該基板 上之半導體密封塡充用薄膜狀樹脂組成物及半導體晶片之 準備步驟A;準備半導體晶片、貼附於該半導體晶片上之 半導體密封塡充用薄膜狀樹脂組成物及基板之準備步驟B 等。 -34- 201235395 (準備步驟A ) 準備步驟A係以使第2層配置於基板側之方式,將半 導體密封塡充用薄膜狀樹脂組成物貼附於基板之電極面上 〇 至於於基板之電極面上貼附半導體密封塡充用薄膜狀 樹脂組成物之方法,列舉爲例如使用熱輥層合機或真空層 合機之方法。 (準備步驟B ) 準備步驟係實施在具有形成有複數個突出物之突出物 形成面之半導體晶圓之該突出物形成面上,以使第1層相 對於第2層配置於半導體晶圓側之方式貼附半導體密封塡 充用薄膜狀樹脂組成物之貼合步驟,及使經過第1步驟之 半導體晶圓單粒化,獲得貼附有半導體密封塡充用薄膜狀 樹脂組成物之半導體晶片之單粒化步驟。 準備步驟B由於可一次製作複數個貼附有半導體密封 塡充用薄膜狀樹脂組成物之半導體晶片,故生產性優異。 於半導體晶圓之突出物形成面上貼附半導體密封塡充 用薄膜狀樹脂組成物之方法,列舉爲例如使用熱輥層合機 或真空層合機之方法。 此處,相對於如上述之第2樹脂組成物總量之第2樹 脂組成物中之塡料的質量比率較少(例如未達20質量% ) 時,第2層由於光透過性優異,故可透過第2層辨識突出 -35- 201235395 物前端。因此,單粒化步驟或後述之連接步驟中,可以突 出物之前端作爲基準進行位置對準,而提高作業性。 半導體晶圓之單粒化可藉由例如刮刀切晶、雷射切晶 、隱形切晶(stealth dicing )等進行。此時,半導體晶圓 可固定於使切片膠帶貼附於半導體晶圓之與突出物形成面 相反側之面上之切晶裝置上,亦可固定於將切晶膠帶貼合 於貼附於半導體晶圓上之半導體密封塡充用薄膜狀樹脂組 成物上之切晶裝置上。 準備步驟B可將半導體密封塡充用薄膜狀樹脂組成物 貼附於經背部硏磨加工而薄化加工至預定厚度之半導體晶 圓上。另外,於施以背部硏磨加工前之半導體晶圓上貼附 半導體密封塡充用薄膜狀樹脂組成物後,亦可以與半導體 密封塡充用薄膜狀樹脂組成物鄰接之方式貼合背部硏磨膠 帶,使突出物形成面與相反側之面經背部硏磨加工薄化加 工成爲特定厚度。 又,準備步驟B亦可針對施以背部硏磨加工前之半導 體晶圓,沿著切晶線,以切晶裝置進行半加工形成溝槽後 ,將半導體密封塡充用薄膜狀樹脂組成物貼附於突出物形 成面上。該情況下,可以與半導體密封塡充用薄膜狀樹脂 組成物鄰接之方式貼合背部硏磨膠帶,自與突出物形成面 相反側之面,藉由背部硏磨使上述溝槽露出,使半導體晶 圓薄化之同時使半導體晶片單粒化。 連接步驟係使基板之電極與半導體晶片之突出物電連 接。連接步驟可例如透過半導體密封塡充用薄膜狀樹脂組 -36- 201235395 成物使半導體晶片與基板成對向配置,邊在焊料或錫之熔 點以上之溫度加熱邊加壓而進行。藉此,焊料或錫之表面 氧化膜可藉由第2層(或第2層及第1層)中所含之助焊 劑去除’同時使焊料或錫快速熔解,使半導體晶片之突出 物與基板之電極金屬接合。 此處’半導體密封塡充用薄膜狀樹脂組成物係分別以 第〗層位在半導體薄膜側,第2層位在基板側之方式配置 。藉此’可充分抑制凹陷之產生,製造具有良好導電性及 連接信賴性之半導體裝置。 加熱加壓時間較好爲0.1〜2 0秒,更好爲0.1〜1 5秒, 又更好爲〇 · 1〜1 〇秒。藉由使加熱加壓時間爲0.1秒以上, 可自突出物與電極間充分排除樹脂組成物,同時均勻地去 除焊料或錫之表面氧化膜,故有進一步提高連接信賴性之 傾向。且,連接時間超過2 0秒時,有生產性下降之虞。 連接步驟可包含在第2層中所含助焊劑之活化溫度以 上、焊料或錫之熔點以下之溫度下加熱加壓之第一加熱步 驟,及在焊料或錫之熔點以上之溫度加熱加壓而使半導體 晶片之突出物與基板之電極金屬接合之第二加熱步驟。 第一加熱步驟爲將藉由加熱而將低黏度化之樹脂組成 物自突出物與基板電極間排除,同時藉由助焊劑去除焊料 或錫之表面氧化膜。第一加熱步驟後之焊料或錫由於以樹 脂組成物被覆故而防止再氧化。且,於第一加熱步驟,使 樹脂組成物中之低分子量成分揮發或高分子化。 依據第一加熱步驟,由於自突出物與基板電極間充分 -37- 201235395 排除樹脂組成物,故可進一步抑制凹陷之產生。又,第一 加熱步驟中由於樹脂組成物中之低分子量成分揮發或高分 子化,故在第二加熱步驟之高溫連接條件下,可抑制低分 子量成分揮發及孔隙產生。 第一加熱步驟之加熱時間通常較好爲0.1〜20秒,更 好爲0.5〜1 5秒,又更好爲1.0〜1 5秒。加熱時間爲〇. 1秒 以上時,可均勻地去除焊料或錫之表面氧化膜,同時充分 地進行突出物與基板電極間之樹脂排除,故有進一步提高 連接信賴性之傾向。又,加熱時間超過2

EMBODIMENT OF THE INVENTION: TECHNICAL FIELD The present invention relates to a film-like resin composition for semiconductor sealing and filling, a method for manufacturing a semiconductor device, and a semiconductor device. [Prior Art] In recent years, with the advancement of miniaturization and high functionality of electronic devices, semiconductor devices have been required to be smaller, thinner, and improved in electrical characteristics (correspond to high-frequency transmission). Along with this, from the conventional method of mounting a semiconductor wafer on a substrate by wire bonding, a flip chip in which a conductive bump electrode called a protrusion is formed on the semiconductor wafer and directly connected to the substrate electrode is started. The connection method is carried out. As for the protrusion formed on the semiconductor wafer, a protrusion made of solder or gold is used. However, in order to achieve fine connection in recent years, a solder layer or a tin layer is formed on the front end of the copper pillar. In order to achieve high reliability, the protrusions are required to be joined by metal bonding, and not only solder joints using solder bumps but also metal using protrusions in which a solder layer or a tin layer is formed at the front end of the copper post. In the case of "gold bumps", a solder layer or a tin layer is formed on the substrate electrode side to form a metal bonding connection method. Further, in the flip chip connection method, since thermal stress due to a difference in thermal expansion coefficient between the semiconductor wafer and the substrate is concentrated on the connection portion and the connection portion is broken, it is necessary to disperse the thermal stress and improve connection reliability. Resin-5- 201235395 Seals the gap between the semiconductor wafer and the substrate. In general, a resin sealing method is used in which a semiconductor wafer is connected to a substrate by using solder or the like, and a liquid sealing resin is injected into the space by capillary action. When the wafer is bonded to the substrate, the metal oxide is easily removed by reduction and removal of the surface oxide film such as solder, and a flux made of rosin or an organic acid or the like is used. Here, if the flux residue remains, when the liquid resin is injected, bubbles called pores are generated, or wiring corrosion occurs due to the acid component, and the connection reliability is lowered. Therefore, it is necessary to carry out the step of washing the residue. However, in recent years, as the gap between the connection gaps is narrowed, the gap between the semiconductor wafer and the substrate is narrowed, so that it is difficult to clean the flux residue. Further, it takes a long time to inject a liquid resin into a narrow space between the semiconductor wafer and the substrate, and there is a problem that productivity is lowered. In order to solve the problem of such a liquid sealing resin, it has been proposed to supply a sealing resin to a substrate by using a sealing resin having a property (flux activity) for reducing and removing an oxide film on a surface of a solder or the like, and then connecting the semiconductor wafer to the substrate. At the same time, a method of connecting the semiconductor wafer and the gap between the substrates by a resin seal and omitting the cleaning of the flux residue is referred to as a first supply method (for example, refer to Patent Documents 1 to 5). [Patent Document 1] [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. [Patent Document 5] Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. 2005-239. The thermal expansion coefficient and the prepared material may be sandwiched between the protrusion and the substrate electrode to cause a connection failure called trapping, which causes poor conduction, and the protrusion or the substrate is used as a starting point for the protrusion or the substrate. Cracks are generated in the electrodes, which reduces the reliability of the connection. An object of the present invention is to provide a film-like resin composition for semiconductor sealing and filling, which can sufficiently suppress the occurrence of dents and obtain a semiconductor device having good conductivity and connection reliability, when used as a sealing resin for a first supply method, and A semiconductor device using the same and a method of manufacturing the same. [Means for Solving the Problems] The present invention provides a film-like resin composition for semiconductor sealing and filling, which is provided with a first layer composed of a first resin composition containing a thermosetting resin and a coating material, and The mass ratio of the second layer formed of the second resin composition of the flux to the second resin composition in the total amount of the second resin composition is larger than the first resin composition The mass ratio of the dip in the first resin composition of the total amount is smaller. According to the present invention, it is possible to prevent the material from being sandwiched between the protrusion and the substrate electrode, and a good connection portion can be formed. That is, according to the semiconductor-sealed 201235395 packaged film-form resin composition of the present invention, the generation of the depression can be sufficiently suppressed, and a conductor having good conductivity and a conductor can be obtained. Further, according to the semiconductor sealing package of the present invention, the heated additive when the semiconductor wafer and the substrate are bonded is cured, and the first resin composition after curing is filled with the connection portion of the electrode. According to this, the formation of a connection failure such as a hot portion and a crack due to a difference in thermal expansion coefficient between the cold body wafer and the substrate after the completion of the connection can be sufficiently improved by the film-like resin assembly according to the semiconductor sealing compound. Semiconductor device. The second resin composition of the present invention further contains thermoplasticity. The second layer composed of the film-like resin composition of the semiconductor sealing compound has a low surface adhesion. In the semiconductor manufacturing method, the semiconductor layer obtained by singulating the semiconductor wafer to which the semiconductive film-like resin composition is singulated into a half layer is attached to the surface of the second layer, and the present invention provides a method of manufacturing a semiconductor device. A semi-conductive method of forming a substrate having a plurality of electrode-facing surfaces of a plurality of protrusions, wherein the film-forming resin composition of the present invention is used as described above The second layer phase is disposed on the substrate side, and the semi-film-like resin composition of the connection reliability attached to the base supply method presses the first resin group to form a strong protrusion and the substrate, and the semiconductor stress concentration is concentrated. Connected to suppression. That is, the composition can be obtained as a resin composition, preferably a resin. The second resin is used for the purpose of preventing the effect when the thin conductor wafer is filled with a body seal, which will be described later. a first step of sealing the electrode surface of the first layer of the conductor layer -8-201235395 with a conductor wafer and a semiconductor wafer of a specific device, and the substrate and the substrate of the first step The semiconductor wafer is disposed such that the electrode surface and the protrusion forming surface are opposed to each other via the semiconductor sealing and filling film-like resin composition, and are heated and pressed to protrude the electrode of the substrate and the semiconductor wafer. The second step of electrically connecting the material; and the surface of at least one of the electrode and the protrusion connected in the second step is tin or solder. By disposing the film-like resin composition of the present invention on the surface of the substrate, the protrusion of the semiconductor wafer and the electrode of the substrate are brought into contact with the second layer having a small mass ratio of the material, thereby suppressing the sandwiching of the material. At the same time, the oxide film at the tip end of the protrusion is removed by the flux in the second layer to facilitate metal bonding with the substrate electrode. According to still another aspect of the invention, there is provided a method of manufacturing a semiconductor device comprising: a semiconductor wafer having a protrusion forming surface on which a plurality of protrusions are formed; and a semiconductor device having a substrate having a plurality of electrodes; The semiconductor resin composition of the present invention is filled with a film-like resin composition, and the first layer is attached to the semiconductor wafer side so that the first layer is disposed on the semiconductor wafer side, and a plurality of protrusions are formed. a first step of forming the protrusion forming surface of the semiconductor wafer on the protrusion forming surface, and singulating the semiconductor wafer by the first step to obtain a film-like resin composition for sealing the semiconductor sealing film The second step of the semiconductor wafer and the semiconductor wafer and the substrate obtained in the second step are disposed such that the protrusion forming surface and the electrode surface are interposed between the semiconductor sealing and filling film-like resin composition. Oppose each other and heat and press to make the -9-201235395 protrusion of the aforementioned semiconductor wafer The third step of the electrode is electrically connected to the substrate; and in that the electrodes and the protrusions of the third step of connecting at least one among the surface, the presence of tin or solder. By disposing the film-like resin composition of the present invention on the surface of the semiconductor wafer, the protrusion of the semiconductor wafer and the electrode of the substrate are brought into contact with the second layer having a small mass ratio of the material, thereby suppressing the pinching of the material. At the same time, the oxide film at the tip end of the protrusion is removed by the flux in the second layer to facilitate metal bonding with the substrate electrode. According to the method for producing a semiconductor device of the present invention, since the film-like resin composition for semiconductor sealing rinsing of the present invention is used, it is possible to sufficiently suppress the occurrence of dents, and it is possible to manufacture a semiconductor device having excellent conductivity and connection reliability. The present invention further provides a semiconductor device manufactured by the method of manufacturing a semiconductor device of the present invention described above. Since the semiconductor device is sealed and filled with the film-like resin composition for semiconductor sealing and filling of the present invention, it is possible to suppress the occurrence of connection failure or cracking due to the occurrence of the depression, and to have good conductivity and connection reliability. According to the present invention, it is possible to provide a film-like resin composition for semiconductor sealing and filling of a semiconductor device having excellent conductivity and connection reliability when the sealing resin used as the first supply method is used. And a semiconductor device using the same and a method of manufacturing the same. [Embodiment] -10- 201235395 A preferred embodiment of the present invention will be described below. The film-like resin composition for semiconductor sealing and filling of the present embodiment is a second layer composed of a first layer composed of a first resin composition containing a coating material and a second resin composition containing a flux. The mass ratio of the dip in the second resin composition to the total amount of the second resin composition is smaller than the mass ratio of the dip in the first resin composition relative to the total amount of the first resin composition. . Here, the second resin composition may or may not contain a dip. In other words, the "mass ratio of the dip in the second resin composition to the total amount of the second resin composition" may be 〇% by mass. According to the film-like resin composition for semiconductor sealing rinsing of the present embodiment, the occurrence of depressions in the first supply mode can be sufficiently suppressed. For this reason, a semiconductor device having good conductivity and connection reliability can be obtained by using the film-like resin composition for semiconductor sealing of the present embodiment. (First layer) The first layer is a layer composed of a first resin composition containing a dip. As for the dip, the inorganic dip is better used. When the inorganic resin material is used, since the thermal expansion coefficient of the first resin composition (or a cured product thereof) is lower, the connection reliability of the semiconductor device sealed and filled with the semiconductor resin sealing film-filled resin composition is improved. As the inorganic pigment, it is exemplified by glass, sulphur dioxide (Silica), oxidized crystal (alumina), oxidized chin (titania), magnesia (magnesia), carbon black, mica, barium sulfate and the like. These can be used alone or in combination -11 - 201235395 or higher. Further, as the inorganic material, two or more kinds of metal compounds may be used (not those in which two or more kinds of metal oxides are simply mixed, and the oxides are chemically bonded to each other to be inseparable). a composite oxide of at least two elements selected from titanium, aluminum, boron and magnesium. More specifically, for example, a composite oxide of silica sand and titanium oxide, a composite oxide composed of alumina, and a compound composed of boron oxide and aluminum oxide, which is composed of cerium oxide, aluminum oxide, and magnesium oxide. Wait. These composite oxides may be used singly or in combination of two or more kinds thereof in combination with the above-mentioned inorganic materials. Further, in the present embodiment, for the purpose of suppressing the pores, it is also possible to use a combination of the porous inorganic cerium and the organic cerium as a dip. The organic cerium is exemplified by, for example, an acrylic resin, a polydecene diene rubber, a polyester, a polyamine. A resin component such as a carboxylic acid ester, a polyvinyl butyral acid ester, a polymethyl methacrylate, an acrylic rubber, a polyphenylene styrene, an SBR or a polyfluorene-modified resin is preferably used as the organic material. The organic fine particle fine particles having an organic fine particle having a molecular weight of 1,000,000 or more or having a three-dimensional crosslinked structure have high dispersibility to the resin composition. Further, the adhesiveness of the film-form resin composition and the stress relaxation after curing are contained. Here, the polymer chain of the resin having the "three-dimensional crosslinked structure" as the surface microparticles has a three-dimensional mesh structure. The resin of this structure is made of, for example, a composite oxygen having a plurality of reaction points, but a metal. This kind of non-combination group is listed as a composite oxide oxide of ruthenium and oxidized, and is also moderately tempered, ruthenium resin, butyl, polypropylene, and NBR I. The resin. The organic fine particles and the properties are more preferably formed, and the compound is obtained by treating a crosslinking agent having two or more functional groups bonded to the reaction point with -12 to 201235395. It is preferred that the organic fine particles having a resin having a molecular weight of 1,000,000 or more and the organic fine particles having a three-dimensional crosslinked structure have low solubility in any solvent. The above effects can be obtained more remarkably by the organic fine particles having a low solubility in a solvent. Further, from the viewpoint of obtaining the above effects more remarkably, the organic fine particles are preferably an alkyl (meth)acrylate-polyoxyalkylene copolymer, a polyfluorene-(meth)acrylic acid copolymer or the like. Organic microparticles composed of a composite. As the organic tanning material, an organic microparticle having a core-shell type configuration and a composition different from that in the shell layer can be used. Specifically, the core-shell type organic fine particles are particles obtained by grafting an acrylic resin with a polyfluorene-acrylic rubber as a core, and grafting an acrylic resin or a styrene resin with a butadiene rubber as a core. When organic fine particles having a resin having a molecular weight of 100,000 or more or organic fine particles having a three-dimensional crosslinked structure are used as the organic fine material, since the solubility in an organic solvent is low, it is easy to be directly contained in the state of maintaining the particle shape. In a film-like resin composition. According to this, the organic fine particles can be dispersed into an island shape in the film-like resin composition, and the strength of the film-form resin composition after curing can be further enhanced. The shape of the dip material is not particularly limited, and is exemplified by a broken shape, a needle shape, a scale shape, a spherical shape, and the like. Among these, the shape of the dip is preferably spherical. Since the spherical material has good dispersibility in the resin composition, it is possible to prevent the niobium from being concentrated on a specific portion of the resin composition and to easily sandwich between the protrusion and the substrate electrode, thereby obtaining a semiconductor having excellent connection reliability. Device. Further, when the material -13-201235395 is spherical, the viscosity control of the resin composition tends to be easy. Further, the spherical shape here does not necessarily have to be a true ball, and may be a slightly spherical shape. The size of the coating material may be smaller than the gap between the semiconductor wafer and the substrate when the flip chip is connected. The average particle diameter of the dipstick can increase the enthalpy density and make the viscosity control of the resin composition easy, and is preferably 1 Ομηη or less, more preferably 5 μmη or less, and still more preferably 3 μηι or less. Further, the lower limit of the average particle diameter of the dip material is not particularly limited, and for example, an average particle diameter of 0 can be used. 01 μηι or more. Further, in order to obtain more remarkable effects (good conductivity and connection reliability) in the film-like resin composition for semiconductor sealing and filling of the present embodiment, the average particle diameter of the material can be set to 0. 05~0·9μιη, can also be 0. 1~0. 8μηι. Further, the average particle diameter herein is obtained by using a particle size distribution measuring device using a laser light diffraction method with a median diameter. The diameter of the middle cymbal indicates that the cumulative ratio in the particle size distribution of the number basis is 50% of the particle diameter (D50). The mass ratio of the dip in the first resin composition to the total amount of the first resin composition is preferably 20 in terms of lowering the thermal expansion coefficient of the first resin composition (or a cured product thereof). In the case of further increasing the mechanical strength of the first resin composition (or a cured product thereof), it is more preferably 30% by mass or more, and the first resin composition (or a cured product thereof) is further reduced. From the viewpoint of water absorption, it is more preferably 40% by mass or more. The upper limit of the mass ratio of the dip in the first resin composition of the total amount of the first resin composition is not particularly limited, and may be, for example, 70 mass to 14 to 2012,35,395 395 % by weight, or 60 mass. When the amount is more than 70% by mass, the first resin composition becomes brittle and the workability tends to be lowered. When the organic material is used in combination with the inorganic material, the mass ratio of the organic material is preferably from 1 to 10% by mass based on the first resin composition. When the amount is 1% by mass or more, the effect of suppressing the pores or the stress relaxation effect by the organic material can be remarkably obtained. When the amount is 1% by mass or less, the viscosity of the resin composition is suppressed, and the surface of the film-like resin composition can be reduced. The unevenness suppresses the occurrence of voids and further improves the adhesion. The first resin composition preferably contains a thermosetting resin. Thereby, the first resin composition is cured under heat and pressure when the semiconductor wafer and the substrate are joined, and the cured first resin composition can reinforce the connection portion between the protrusion and the substrate electrode. Therefore, during the cooling process after the completion of the connection, the thermal stress caused by the difference in thermal expansion coefficient between the semiconductor wafer and the substrate is sufficiently suppressed from being concentrated on the connection portion to cause connection failure such as cracking. In other words, by providing the first resin composition with a thermosetting resin, the connection reliability of the obtained semiconductor device is further improved. The thermosetting resin is exemplified by a phenol resin, a cyanate resin, a benzocyclobutene resin, an acrylate resin, a methacrylate resin, an epoxy resin or the like. The first resin composition preferably contains an epoxy resin as a thermosetting resin because it is excellent in heat resistance and excellent in workability. For example, an epoxy resin having two or more functional groups (an epoxy resin having two or more epoxy groups in the molecule) is used as the epoxy resin. The epoxy resin can be used, for example, a bisphenol A type epoxy resin, a bisphenol F type epoxy resin, a bisphenol S type epoxy resin, a phenol novolak type epoxy resin, a cresol novolac type epoxy-15 - 201235395 Resin, biphenyl type epoxy resin, hydroquinone type epoxy resin, epoxy resin containing diphenyl sulfide skeleton, phenol aralkyl type polyfunctional epoxy resin, polyfunctional epoxy resin containing naphthalene skeleton a polyfunctional epoxy resin containing a dicyclopentadiene skeleton, a polyfunctional epoxy resin containing a triphenylmethane skeleton, an aminophenol type epoxy resin, a diaminodiphenylmethane type epoxy resin, Other various polyfunctional epoxy resins and the like. In these epoxy resins, the low viscosity of the resin composition can be easily achieved, the water absorption of the resin composition (or a cured product thereof) can be lowered, and the dimensional change can be made more difficult. Further improvement of the resin composition (or a cured product thereof) From the viewpoint of heat resistance and the like, a bisphenol A type epoxy resin, a bisphenol F type epoxy resin, a polyfunctional epoxy resin containing a naphthalene skeleton, and a polyfunctional group containing dicyclopentadiene are preferably used. An epoxy resin, a polyfunctional epoxy resin containing a triphenylmethane skeleton, or the like. As for the properties of the epoxy resin, it is liquid or solid at 25 t. Further, these epoxy resins may be used singly or in combination of two or more. The first resin composition may further contain a curing agent. The hardener can be appropriately selected depending on the type of the thermosetting resin. For example, when the first resin composition contains an epoxy resin as a thermosetting resin, imidazoles, acid anhydrides, amines, phenols, hydrazines, polythiols, Lewis acid-amine complexes, or the like can be used. hardener. Among these curing agents, imidazoles, acid anhydrides, and amines are preferably used because of the low viscosity of the resin composition, excellent storage stability, and improved heat resistance of the cured product of the resin composition. Classes, phenols. Further, it is preferable to use a polyurethane material, a polyester polymer material or the like and to use a microencapsulated product as a curing agent, since the usable time can be extended. The above imidazoles are exemplified by 2-methylimidazole, 2-undecylimidazole, 2-phenylimidazole, 2-ethyl-4-methylimidazole, 2-phenyl-4-methylimidazole, 1-benzyl 2-methylimidazole, benzyl-2-phenylimidazole, 1-cyanoethyl-2-methylimidazole, 1-cyanoethyl-2-undecylimidazole, 1-cyanoethyl-2- Ethyl-4-methylimidazole, 1-cyanoethyl-2-phenylimidazole, 1-cyanoethyl-2-undecylimidazole, trimellitate, 1-cyanoethyl-2-benzene Pyrimidine gun trimellitate, 2,4-diamino-6-[2'-methylimidazolyl-(1')]-ethyl-3-triazine, 2,4-diamino- 6-[2,-undecyl imidazolyl-(1')]-ethyl-s-triazine, 2,4-diamino-6-[2'-ethyl-4'-methylimidazole -(1,)]-ethyl-s-triazine, 2,4-diamino-6-[2'-methylimidazolyl-(1,)]-ethyl-s-trimeric isocyanide Acid addition product, 2,4-diamino-6-[2'-methylimidazolyl-(1')]-ethyl-3-trimeric isocyanate adduct, 2-phenylimidazole III Polyisocyanate adduct, 2-phenyl-4,5-dihydroxymethylimidazole, 2-phenyl-4-methyl-5-hydroxymethylimidazole, and the like. Further, a compound obtained by adding an epoxy resin to the imidazoles may also be used. For the imidazoles, for example, 2ΜΖ, Cl 1Ζ, 2ΡΖ′ 2Ε4ΜΖ, 2Ρ4ΜΖ, 1Β2ΜΖ, 1Β2ΡΖ, 2MZ-CN, 2E4MZ-CN, 2PZ-CN, C11Z-CN, 2PZ-CNS, C11Z-CNS, 2ΜΖ-Α, C11Z-A, 2Ε4ΜΖ-Α, 2Ρ4ΜΗΖ, 2ΡΗΖ, 2ΜΑ-ΟΚ, 2ΡΖ-ΟΚ (all manufactured by Shikoku Chemical Industry Co., Ltd., product name). Further, the above-mentioned imidazoles may be used singly or in combination of two or more. The amount of the imidazole to be added to the first resin composition is preferably from 0 to 100 parts by mass based on the total amount of the epoxy resin in the first resin composition. 1~1Q parts by mass, more preferably 0. 5 to 10 parts by mass, more preferably 1 to 10 parts by mass. -17- 201235395 The amount of deployment is ο.  When the amount of the epoxy resin is sufficiently increased, the above-described effects can be exhibited more reliably (the connection reliability is more excellent, etc.). Further, the amount of the preparation is 10 parts by mass or less, and the storage stability is improved.

From the viewpoint of improving the properties, it is preferred to use methyltetrahydrobenzene dianhydride, methyl hexahydrophthalic anhydride, bridge-methylenetetrahydrophthalic acid bridge-methylenetetrahydrobenzene Formic acid, 3,4-dimethyl-6-(2-methyl-alkenyl)-4-cyclohexene-1,2-dicarboxylic anhydride, 1-isopropyl-4-methyl-[2. 2·2] oct-5-ene·2,3-dicarboxylic anhydride, ethylene glycol trimellitate triol phthalic anhydride ester, and the like. These may be used alone or in combination.

The moisture resistance of the cured product of the resin composition may be lowered. In other words, when the ratio (Ν! /Ν2) is 0.5 or more, the moisture resistance of the cured product of the resin composition is further improved. Also, the ratio (Ni/lSh) is 1. When it is 5 or less, the curing of the epoxy resin is sufficiently performed, and the above effects are more reliably exhibited (the connection reliability is more excellent, etc.).

(Preparation step B) The preparation step is performed on the protrusion forming surface of the semiconductor wafer having the protrusion forming surface on which the plurality of protrusions are formed, so that the first layer is disposed on the semiconductor wafer side with respect to the second layer In the method of attaching a film-like resin composition for semiconductor sealing and filling, and singulating the semiconductor wafer subjected to the first step, a semiconductor wafer to which a film-like resin composition for semiconductor sealing is attached is obtained Granulation step. In the preparation step B, since a plurality of semiconductor wafers to which a film-like resin composition for semiconductor sealing is attached can be produced at one time, the productivity is excellent. A method of attaching a semiconductor sealing film to a film-forming resin composition on a projection forming surface of a semiconductor wafer is exemplified by a method using a hot roll laminator or a vacuum laminator. When the mass ratio of the coating material in the second resin composition as the total amount of the second resin composition as described above is small (for example, less than 20% by mass), the second layer is excellent in light transmittance. The front end of the -35-201235395 can be highlighted through the second layer. Therefore, in the singulation step or the joining step described later, the front end of the projection can be aligned as a reference to improve workability. The singulation of the semiconductor wafer can be performed by, for example, doctor blade dicing, laser dicing, stealth dicing, or the like. In this case, the semiconductor wafer may be fixed to the dicing device that attaches the dicing tape to the surface of the semiconductor wafer opposite to the protrusion forming surface, or may be fixed to the dicing tape attached to the semiconductor. The semiconductor sealing on the wafer is filled with a dicing device on the film-like resin composition. In the preparation step B, the semiconductor sealing compound can be attached to the semiconductor wafer having a predetermined thickness by a back-grinding process by attaching a film-like resin composition. In addition, after attaching the film-like resin composition for semiconductor sealing to the semiconductor wafer before the back honing process, the back honing tape may be attached to the semiconductor sealing enamel film-like resin composition. The protrusion forming surface and the opposite side surface are subjected to back honing processing and thinning to a specific thickness. Further, in the preparation step B, the semiconductor wafer before the back honing processing may be applied, and the trench is formed by a dicing device along the dicing line, and then the semiconductor sealing film is attached with the film-like resin composition. On the protrusion forming surface. In this case, the back honing tape can be bonded to the semiconductor sealing rinsing film-like resin composition, and the groove can be exposed by back honing from the surface opposite to the surface on which the protrusion is formed, so that the semiconductor crystal is exposed. The wafer is singulated while being thinned. The connecting step electrically connects the electrodes of the substrate to the protrusions of the semiconductor wafer. The connecting step can be carried out, for example, by arranging the semiconductor wafer and the substrate in a direction opposite to the melting point of the solder or tin at a temperature higher than the melting point of the solder or tin. Thereby, the surface oxide film of the solder or tin can be removed by the flux contained in the second layer (or the second layer and the first layer) while simultaneously melting the solder or tin to make the protrusion and the substrate of the semiconductor wafer The electrode is metal bonded. Here, the film-like resin composition for semiconductor sealing is disposed so that the first layer is on the side of the semiconductor film and the second layer is on the side of the substrate. Therefore, the semiconductor device having good conductivity and connection reliability can be manufactured by sufficiently suppressing the occurrence of pits. The heating and pressing time is preferably 0. 1~2 0 seconds, better 0. 1~1 5 seconds, and better for 〇 · 1~1 leap seconds. By heating and pressing time is 0. For more than 1 second, the resin composition can be sufficiently excluded from the protrusion and the electrode, and the surface oxide film of the solder or tin can be uniformly removed, so that the connection reliability is further improved. Moreover, when the connection time exceeds 20 seconds, there is a drop in productivity. The connecting step may include a first heating step of heating and pressurizing at a temperature above the activation temperature of the flux contained in the second layer, below the melting point of the solder or tin, and heating and pressurizing at a temperature above the melting point of the solder or tin. A second heating step of bonding the protrusions of the semiconductor wafer to the electrode metal of the substrate. The first heating step is to remove the low-viscosity resin composition from the protrusion and the substrate electrode by heating while removing the surface oxide film of the solder or tin by the flux. The solder or tin after the first heating step is prevented from being reoxidized by being coated with the resin composition. Further, in the first heating step, the low molecular weight component in the resin composition is volatilized or polymerized. According to the first heating step, since the resin composition is sufficiently excluded from the protrusion and the substrate electrode, the generation of the depression can be further suppressed. Further, in the first heating step, since the low molecular weight component in the resin composition is volatilized or highly molecularized, volatilization of the low molecular weight component and generation of pores can be suppressed under the high temperature joining condition of the second heating step. The heating time of the first heating step is usually preferably 0. 1 to 20 seconds, preferably 0. 5 to 1 5 seconds, and better yet 1. 0~1 5 seconds. The heating time is 〇.  When the thickness is more than 1 second, the surface oxide film of the solder or tin can be uniformly removed, and the resin between the protrusion and the substrate electrode can be sufficiently removed, so that the connection reliability tends to be further improved. Further, when the heating time exceeds 20 seconds, the productivity is lowered. However, in the first heating step, if the semiconductor resin composition is gelatinized by the film-like resin composition, the flow of the molten solder or tin is blocked by the gelled resin composition in the second heating step, and it is impossible to Give full play to the wettability. Accordingly, the heating time is preferably set as appropriate depending on the gelation time of the film-like resin composition for the semiconductor sealing compound to be used. The second heating step melts the solder or tin and bonds the protrusions to the substrate electrode metal. Therefore, the heating temperature is set above the melting point of the solder or tin. In the first heating step, since the removal of the surface oxide film of the solder or tin and the removal of the resin between the protrusion and the substrate electrode are completed, in the second heating step, the solder or the tin may be accelerated to be melted, and in the protrusion And the surface of the substrate electrode exhibits good wettability. The heating time of the second heating step is usually preferably 0. 1 to 20 seconds, preferably 0. 5~15 seconds' is better for 1. 〇~15 seconds. By allowing the heating time to be 〇·1 second or more, the solder or tin can sufficiently wet the surface of the protrusion and the substrate electrode -38 - 201235395, so that the connection failure can be further suppressed. Moreover, when the heating time exceeds 20 seconds, the productivity is lowered. However, in the second heating step, the joint portion of the metal joint is reinforced by gelatinizing the semiconductor sealing compound with the film-like resin composition. Therefore, it is expected that the thermal stress caused by the difference in thermal expansion coefficient between the semiconductor wafer and the substrate during the cooling process after the completion of the connection can be suppressed from being concentrated on the connection portion to cause connection failure such as cracks. Therefore, the heating time in the second heating step is appropriately set in accordance with the gelation time in which the film-like resin composition for the semiconductor sealing compound is sufficiently gelatinized. The first heating step and the second heating step may be continuously performed by a single connecting device, but the working time is prolonged due to the temperature rise and cooling of the connecting device, and the productivity is lowered. On the other hand, the first heating step and the second heating step can be separated and separately performed by different connecting means, and the working temperature of the connecting device can be kept constant, and high productivity can be realized. Further, since the connection device having the temperature rising or cooling mechanism (pulse heating mechanism) is not used, and the connection device having the mechanism (fixed heating mechanism) capable of heating to a constant temperature is used, the apparatus can be simplified. In addition, the positional alignment of the semiconductor wafer and the substrate may be performed before the first heating step, at a temperature lower than the activation temperature of the flux and higher than the temperature at which the semiconductor sealing composition is filled with the film-like resin composition to exhibit adhesiveness. A temporary fixing step of temporarily fixing the semiconductor wafer and the substrate is performed. By providing the temporary fixing step, the first heating step and the second heating step can be performed once for the plurality of semiconductor wafers and the substrate, and high production can be achieved -39-201235395. Further, in order to further improve the connection reliability, after the semiconductor wafer and the substrate are connected, heat treatment may be performed in a heating oven or the like to further cure the film-like resin composition for semiconductor sealing and filling. Hereinafter, a semiconductor device manufactured by the manufacturing method of the present embodiment will be described.

The wiring 4 of the circuit board and the semiconductor wafer 5 are electrically connected by the protrusions 3. Further, the circuit board 7 has electrode pads 2 and solder balls 1 provided on the electrode pads 2 on the surface opposite to the surface on which the wirings 4 are provided, so as to be connectable to other circuit members.

When a film-like resin composition is used for charging, a favorable pore state and a good connection portion can be realized, and a semiconductor device excellent in conductivity and connection reliability can be obtained. Fig. 2 is a view showing an observation of the state of the pores of the semiconductor device of the second embodiment observed by the ultrasonic flaw detector. Further, Fig. 3 is a cross-sectional observation photograph showing the connection portion of the semiconductor device of the third embodiment. Further, Fig. 4 is a cross-sectional observation photograph showing a connecting portion of the semiconductor device of the sixth embodiment. In Figs. 3 and 4, the copper pillars 13 of the semiconductor wafer 12 and the electrodes 15 of the substrate 11 are metal-bonded by solder 14. Further, the gap between the substrate 11 and the semiconductor wafer 12 is sealed and filled with a sealing resin 16 which is a semiconductor seal and a cured product of a film-like resin composition. On the other hand, when the film-like resin compositions of Comparative Examples 1 and 5 were used, the solder did not sufficiently wet the wiring (substrate electrode), and a good connection portion could not be formed. Fig. 5 is a cross-sectional observation photograph showing a connection portion of the semiconductor device of Comparative Example 1. In FIG. 5, a recess 17 appears between the copper post 13 of the semiconductor wafer 12 and the electrode 15 of the substrate 11.

Fig. 7 is a view showing an observation image of the state of the pores of the semiconductor device of Comparative Example 3 observed by an ultrasonic flaw detector. Comparative Example 3 From the comparison of Fig. 7 and Fig. 2, it is understood that many pores appear (18 of Fig. 7). When the connection method 2 is carried out, when the film-like resin composition for semiconductor sealing of Examples 7 and 8 is used, the front end of the protrusion can be sufficiently recognized even if the tip end of the protrusion is not exposed to the resin composition and is not exposed. Therefore, the positional alignment of the semiconductor wafer and the substrate can be easily performed.

Further, Fig. 9 is a photograph showing a projection forming surface of a semiconductor wafer to which a film-like resin composition for semiconductor sealing and filling of Example 8 is attached by a camera of a flip chip bonding machine.

In Fig. 10, the solder bumps 23 of the semiconductor wafer 22 and the electrodes 25 of the substrate 21 are metal-bonded by melting of solder. Therefore, the sealing resin 26 filled with the cured product of the film-like resin composition by the semiconductor sealing means seals the gap between the filling substrate 21 and the semiconductor wafer 22.
