Abstract

本發明揭示一種製造半導體裝置的方法,所述半導體裝置具備具備半導體晶片、基板及/或其他半導體晶片、以及介於該些之間的接著劑層。該方法包括:利用暫時壓接用按壓構件夾持具有半導體晶片,及基板、其他半導體晶片或半導體晶圓,及接著劑層的積層體,藉此進行加熱及加壓,由此將基板、其他半導體晶片或半導體晶圓暫時壓接於半導體晶片上的步驟;以及利用有別於暫時壓接用按壓構件所準備的正式壓接用按壓構件夾持積層體,藉此進行加熱及加壓,由此將半導體晶片的連接部與基板或其他半導體晶片的連接部連接的步驟。

Description

半導體用接著劑、製造半導體裝置的方法
本發明是有關於一種半導體用接著劑、半導體裝置及其製造方法。
先前,於將半導體晶片與基板加以連接時,廣泛應用使用金線等金屬細線的打線接合方式,為了應對對於半導體裝置的高功能‧高積體‧高速化等的要求,於半導體晶片或基板上形成被稱為凸塊的導電性突起,而在半導體晶片與基板間直接進行連接的覆晶連接方式(FC(Flip Chip)連接方式)正在推廣。
作為覆晶連接方式,已知有使用焊料、錫、金、銀、銅等進行金屬接合的方法,施加超音波振動來進行金屬接合的方法,藉由樹脂的收縮力來保持機械式接觸的方法等,但就連接部的可靠性的觀點而言,通常為使用焊料、錫、金、銀、銅等進行金屬接合的方法。
例如,於半導體晶片與基板間的連接中,積極地用於球柵陣列(Ball Grid Array,BGA)、晶片尺寸封裝(Chip Size Package,CSP)等的板上晶片(Chip On Board,COB)型的連接方式亦為覆晶連接方式。覆晶連接方式亦廣泛地用於在半導體晶片上形成凸塊或配線,而於半導體晶片間進行連接的疊晶(Chip On Chip,COC)型的連接方式(例如,參照專利文獻1)。
於中央處理單元(Central Processing Unit,CPU)、微處理單元(Micro Processing Unit,MPU)等中所使用的區域陣列型的半導體封裝中,強烈要求高功能化。作為具體的要求,可列舉:晶片的大型化、針(凸塊、配線)數的增加、間距及間隙的高密度化。
於強烈要求進一步的小型化、薄型化、高功能化的封裝中,將所述連接方式加以積層・多段化的晶片堆疊型封裝、層疊封裝(Package On Package,POP)、矽穿孔(Through-Silicon Via,TSV)等亦開始廣泛普及。藉由配置成立體狀而非平面狀,可減小封裝,因此該些技術對於半導體的性能提升及雜訊減少、安裝面積的削減、省電力化亦有效,作為下一代的半導體配線技術而受到矚目。
就提升生產性的觀點而言,將半導體晶片壓接(連接)於晶圓上後加以個片化來製作半導體封裝的晶片堆疊晶圓(Chip On Wafer,COW)、將晶圓彼此壓接(連接)後加以個片化來製作半導體封裝的晶圓堆疊晶圓(Wafer On Wafer,WOW)亦受到矚目。進而,就相同的觀點而言,將多個晶片對位並暫時壓接於晶圓上或圖板上後,一次性地正式壓接所述多個晶片來確保連接的集團接合(gang bonding)方式亦受到矚目。集團接合方式亦用於所述TSV-PKG(Through Silicon Via-Package,TSV封裝)等。 現有技術文獻 專利文獻

[發明所欲解決之課題] 作為所述覆晶封裝的組裝方法,例如可考慮以下的方法。首先,利用夾頭自經切割的晶圓拾取供給有半導體用接著劑的半導體晶片,並供給至壓接用按壓構件。繼而,於晶片-晶片間或晶片-基板間進行對位後,將該些相互暫時壓接。而且,以達到晶片-晶片間或晶片-基板間的連接部的熔點以上的方式使壓接用按壓構件的溫度上升,而於連接部形成金屬結合,然後將晶片與晶片或晶片與基板相互正式壓接。藉由以上方式,可獲得1個覆晶封裝。其後,將於正式壓接時變成高溫的壓接用按壓構件冷卻後,利用壓接用按壓構件再次拾取半導體晶片。當於半導體晶片中供給有半導體用接著劑時,壓接用按壓構件吸附半導體晶片的與供給有半導體用接著劑的面(進行連接的面)相反側的面來拾取半導體晶片。
於自拾取至正式壓接為止的循環中,使用1個壓接用按壓構件,因此必須使壓接用按壓構件的溫度上升至連接部的金屬熔融的高溫為止、或下降至可拾取供給有半導體用接著劑的半導體晶片的低溫為止。但是,使壓接用按壓構件的溫度變化耗費時間,半導體裝置的製造時間變長,因此生產性容易下降。
於加熱至連接部的金屬的熔點以上來確保連接的覆晶連接方式中,正式壓接後的壓接用按壓構件變成高溫(若連接部的金屬為焊料,則例如為240℃以上)。此處,若不冷卻壓接用按壓構件而自夾頭拾取半導體晶片,則壓接用按壓構件的熱傳遞至夾頭上,夾頭本身的溫度上升,因此於拾取時產生不良情況且生產性容易下降。另外,於供給有半導體用接著劑的半導體晶片中,壓接用按壓構件的熱傳遞至夾頭上,半導體用接著劑的溫度因夾頭的熱而上升。藉此,若半導體用接著劑的黏性顯現,則半導體用接著劑容易附著於夾頭上,生產性容易下降。進而,若夾頭高溫化,則當自切割膠帶拾取經個片化的半導體晶片時,熱經由夾頭而傳導至切割膠帶上,拾取性下降且生產性容易下降。
一形態的本發明的目的是關於包括藉由金屬接合來將連接部彼此連接的半導體裝置的製造,且在於可實現更高的生產性。 [解決課題之手段]
本發明的一形態是有關於一種製造半導體裝置的方法,所述半導體裝置具備半導體晶片、基板及/或其他半導體晶片、以及介於該些之間的接著劑層,半導體晶片、基板、及其他半導體晶片分別包含具有由金屬材料形成的表面的連接部,半導體晶片的連接部與基板及/或所述其他半導體晶片的連接部藉由金屬接合而電性連接。該方法依次包括:利用對向的一對暫時壓接用按壓構件夾持具有半導體晶片,及基板、其他半導體晶片或包含相當於其他半導體晶片的部分的半導體晶圓,及配置於該些之間的接著劑層,且半導體晶片的連接部與基板或其他半導體晶片的連接部對向配置的積層體,藉此進行加熱及加壓,由此將基板、其他半導體晶片或半導體晶圓暫時壓接於半導體晶片上的步驟;以及利用有別於暫時壓接用按壓構件所準備的對向的一對正式壓接用按壓構件夾持積層體,藉此進行加熱及加壓,由此藉由金屬接合來將半導體晶片的連接部與基板或其他半導體晶片的連接部電性連接的步驟。於對積層體進行加熱及加壓時,將一對暫時壓接用按壓構件中的至少一個加熱至比形成半導體晶片的連接部的表面的金屬材料的熔點、及形成基板或其他半導體晶片的連接部的表面的金屬材料的熔點更低的溫度。於對積層體進行加熱及加壓時,將一對正式壓接用按壓構件中的至少一個加熱至形成半導體晶片的連接部的表面的金屬材料的熔點、或者形成基板或其他半導體晶片的連接部的表面的金屬材料的熔點中的至少任一個熔點以上的溫度。
利用不同的壓接用按壓構件實施以比形成連接部的表面的金屬材料的熔點更低的溫度進行暫時壓接的步驟、及以形成連接部的表面的金屬材料的熔點以上的溫度進行正式壓接的步驟,藉此可縮短各個壓接用按壓構件的加熱及冷卻所需的時間。因此,能夠以比利用1個壓接用按壓構件進行壓接更短的時間且生產性良好地製造半導體裝置。其結果,可於短時間內製造許多高可靠性的半導體裝置。
於所述方法中,可一面維持將正式壓接用按壓構件加熱至形成連接構件的表面的金屬材料的熔點以上的溫度的狀態,一面重複暫時壓接及正式壓接,而連續地製造多個半導體裝置。
於當暫時壓接時使半導體晶片的連接部與基板或其他半導體晶片的連接部相互接觸的情況下,於正式壓接步驟時可抑制連接部的金屬的流動及飛散。
藉由設為利用各自準備的2個壓接用按壓構件分別進行到暫時壓接為止的步驟與正式壓接步驟,並將正式壓接用的按壓構件維持成高溫的方式,可縮短壓接用按壓構件的加熱及冷卻時間,而可期待生產性的提升。
但是,於該方式中,與先前的方式相比,於正式壓接步驟時連接部的金屬的熔點以上的高溫急速地施加至半導體用接著劑上,因此促進半導體用接著劑的硬化並產生樹脂的流動不足,藉此存在於壓接時捲入的空隙殘留、或因樹脂揮發而產生空隙的情況。進而,因連接部的金屬的熔融與樹脂流動同時產生,故存在產生連接部的金屬的流動或飛散、及由樹脂捕捉所引起的連接不良的情況。
因此,為了獲得充分地抑制空隙的產生、且於連接可靠性方面更優異的半導體裝置,於對暫時壓接用按壓構件進行加熱的溫度下,接著劑層的熔融黏度可為7000 Pa・s以下。藉由暫時壓接步驟時的接著劑層的熔融黏度為7000 Pa・s以下,可更有效地抑制空隙產生及由樹脂捕捉所引起的連接不良。
就提升生產性的觀點而言,因壓接用按壓構件的溫度的上升下降需要時間,故暫時壓接與正式壓接可利用不同的壓接用按壓構件來進行。另外,當進行一次性連接時,於正式壓接中壓接比暫時壓接更多的多個半導體晶片,因此存在使用具備面積大的壓接頭的壓接用按壓構件的傾向。若可如所述般一次性地正式壓接多個半導體晶片來確保連接,則半導體裝置的生產性提升。
當一次性地正式壓接多個半導體晶片時,需要大面積的壓接頭。但是,與先前的組裝1個封裝時所使用的小壓接頭(例如,工具尺寸未滿20 mm左右)相比,壓接多個封裝的大面積的壓接頭(例如,工具尺寸為20 mm左右以上)即便是同等的平行度,面積變得越大,封裝間的高低差亦變得越大。因此,於壓接多個半導體晶片的一次性連接中,因壓接頭的面積變大,故有時於按壓部容易產生凹凸(高低差),於壓接多個半導體晶片來製成封裝時部分地產生連接不良。於半導體晶片的厚度的薄型化,或封裝的小型化、薄型化等正在發展的半導體封裝中,要求更高的連接的精度。
因此,當一次性地正式壓接多個半導體晶片與多個基板、多個其他半導體晶片或半導體晶圓時,為了減少連接不良的半導體裝置的比例,於藉由金屬接合來將半導體晶片的連接部與基板或其他半導體晶片的連接部電性連接的步驟中,可利用平台及與平台對向的壓接頭夾持配置於平台上的多個積層體與以覆蓋該些積層體的方式配置的一次性連接用片材,藉此一次性對多個積層體進行加熱及加壓。一次性連接用片材可具有250℃下的10 GPa以下的儲存彈性模數、及250℃下的40 μm以上的位移量。此處的位移量是於將具有直徑8 μm的圓形的端面的棒狀的按壓用治具擠壓於一次性連接片材的主面上(使主面與端面成為平行的方向)的壓縮試驗中,於250℃的環境下且壓縮負荷為100 N時的位移量。
當壓接多個半導體晶片(積層體)時,藉由使用250℃下的儲存彈性模數為10 GPa以下、250℃下的位移量為40 μm以上的一次性連接用片材,可充分地吸收多個積層體間的高低差並顯現良好的平行度,且對該些均勻地加壓,因此任一個半導體裝置均可確保良好的連接。
當利用與半導體晶片同等或小幾百μm的壓接頭壓接一個半導體晶片時,即便半導體用接著劑的焊點(fillet)(自晶片中的露出部分)量變大,且半導體用接著劑朝按壓半導體晶片的壓接頭方向往上爬,半導體用接著劑亦難以附著於壓接頭上。另一方面,當利用大面積的壓接頭壓接多個半導體晶片時,若焊點量變大並往上爬,則壓接頭被半導體用接著劑污染而需要清洗等,因此存在生產性下降的情況。根據所述製造半導體裝置的方法,即便於壓接時自半導體晶片中露出的接著劑附著於一次性連接用片材上,亦容易更換,因此生產性難以下降。
於本發明的另一形態的方法中,在藉由金屬接合來將半導體晶片的連接部與基板或其他半導體晶片的連接部電性連接的步驟中,於加熱爐內或加熱板上,將積層體加熱至形成半導體晶片的連接部的表面的金屬材料的熔點、或者形成基板或其他半導體晶片的連接部的表面的金屬材料的熔點中的至少任一個熔點以上的溫度。
於該方法的情況下,亦分別實施以比形成連接部的表面的金屬材料的熔點更低的溫度進行暫時壓接的步驟、及以形成連接部的表面的金屬材料的熔點以上的溫度進行加熱的步驟,藉此可縮短暫時壓接用按壓構件的加熱及冷卻所需的時間。因此,能夠以比利用1個壓接用按壓構件進行壓接更短的時間且生產性良好地製造半導體裝置。其結果,可於短時間內製造許多高可靠性的半導體裝置。
於所述方法中,可於加熱爐內或加熱板上一次性對多個積層體進行加熱。藉此,能夠以更高的生產性製造半導體裝置。所述方法中的接著劑層可為含有後述的[1]~[7]的半導體用接著劑的層。
所述接著劑層可為由熱硬化性樹脂組成物所形成的層,所述熱硬化性樹脂組成物含有具有10000以下的分子量的熱硬化性樹脂及其硬化劑。即,所述接著劑層可為含有該熱硬化性樹脂組成物的層。
所述熱硬化性樹脂組成物可進而含有具有10000以上的重量平均分子量的高分子成分。所述高分子成分的重量平均分子量可為30000以上。所述高分子成分的玻璃轉移溫度可為100℃以下。
所述接著劑層可為由事先準備的接著劑膜所形成的層。
然而,例如將多個經個片化的晶片對位並暫時壓接於晶圓上或圖板上後(第一步驟),利用大面積壓接工具一次性地加熱壓接多個晶片來確保連接(第二步驟)的集團接合方式,另外,同樣地將多個經個片化的晶片對位並暫時壓接於晶圓上或圖板上後(第一步驟),於回焊爐或烘箱等的可進行高溫處理的槽內進行熱處理來確保連接(第二步驟)的方式因第二步驟可一次性地組裝多個封裝,故有望提升生產性。於該些方式中,就高可靠性的觀點而言,存在加熱至金屬的熔點以上來形成金屬結合的傾向。
另外,當利用壓接工具拾取供給有半導體用接著劑的半導體晶片時,若以連接部的金屬的熔點以上(例如,若為Sn/Ag焊料,則約為220℃以上)的溫度拾取,則產生由半導體用接著劑的黏性顯現所引起的拾取不良、或由半導體用接著劑的硬化進行所引起的安裝不良(由流動性不足所引起的連接不良或空隙產生),因此必須對壓接工具進行冷卻。
藉由分成第一步驟(對位並進行暫時壓接的步驟)與第二步驟(以連接部的金屬的熔點以上的溫度進行熱處理來確保連接的步驟)來組裝封裝,可省略工具冷卻,生產性提升。
於第二步驟中,就抑制焊點、抑制對於連接部的損害的觀點而言,期待以低負荷或無負荷於回焊爐或烘箱等的可進行高溫處理的槽內進行熱處理來確保連接的方式。
第二步驟因無負荷,故存在對確保連接及抑制空隙造成影響的樹脂流動(半導體用接著劑的流動)不足的傾向。因此,必須於低溫的第一步驟中確保流動性。
藉由在第一步驟中加以無空隙化,並確保連接(接觸),可提升第二步驟後的安裝性(抑制空隙、確保連接)。
於可提升生產性的分成第一步驟與第二步驟來組裝的製造法中,在第一步驟中,半導體用接著劑的流動性不足且空隙容易殘存,難以確保連接(接觸)。若於第一步驟中空隙抑制與連接(接觸)的確保並不充分,則於第二步驟後空隙亦殘存,有可能變成連接不良。
本發明的另一形態是為了解決所述課題而成者,其目的在於提供一種半導體用接著劑、使用其的半導體裝置的製造方法及半導體裝置,所述半導體用接著劑即便於用於經由所述第一步驟及第二步驟來製造半導體裝置的方法的情況下,亦可抑制空隙並確保良好的連接(接觸),且可獲得良好的耐回焊性。
本發明的另一形態的主要目的為即便是於第一步驟中確保充分的流動性,並抑制空隙與確保連接(接觸),藉此於第二步驟中可期待高生產性的一次性組裝的方式(回焊爐等的加熱處理),亦可確保高可靠性(抑制空隙、確保連接、耐回焊性),而提供下述[1]~[7]。

根據本發明的一形態,關於包括藉由金屬接合來將連接部彼此連接的半導體裝置的製造,可達成更高的生產性。

<半導體裝置的製造方法> 第一實施形態 圖1是表示於本實施形態的半導體裝置的製造方法中,將基板暫時壓接於半導體晶片上的步驟的一例的步驟圖。
首先,如圖1的(a)所示,一面在具有半導體晶片本體10、及作為連接部的凸塊30的半導體晶片1與具有基板本體20、及作為連接部的配線16的基板2之間配置接著劑層40,一面將所述半導體晶片1與所述基板2疊加,而形成積層體3。藉由半導體晶圓的切割來形成半導體晶片1後,拾取該半導體晶片1並搬送至基板2上為止,且以使作為連接部的凸塊30與配線16對向配置的方式進行對位。積層體3形成於具有作為經對向配置的一對暫時壓接用按壓構件的壓接頭41及平台42的暫時壓接用的按壓裝置43的平台42上。凸塊30設置於半導體晶片本體10上所設置的配線15上。基板2的配線16設置於基板本體20上的規定的位置上。凸塊30及配線16分別具有由金屬材料形成的表面。
接著劑層40可為藉由將事先準備的接著劑膜貼附於基板2上所形成的層。接著劑膜可藉由加熱壓製、輥層壓、真空層壓等來貼附。接著劑膜的供給面積及厚度對應於半導體晶片1或基板2的尺寸、連接部的高度等而適宜設定。接著劑膜亦可貼附於半導體晶片1上。亦可將接著劑膜貼附於半導體晶圓上,其後對半導體晶圓進行切割來將半導體晶圓加以個片化,藉此製作貼附有接著劑膜的半導體晶片1。
繼而,如圖1的(b)所示,利用作為暫時壓接用按壓構件的平台42及壓接頭41夾持積層體3,藉此進行加熱及加壓,由此將基板2暫時壓接於半導體晶片1上。於圖1的實施形態的情況下,壓接頭41配置於積層體3的半導體晶片1側,平台42配置於積層體3的基板2側。暫時壓接能夠以半導體晶片1的連接部與基板2的連接部接觸的方式進行。藉此,於後續的加熱步驟中容易形成連接部間的金屬接合,並且可減少接著劑層朝連接部間的齧入,連接性進一步提升。
於為了暫時壓接而對積層體3進行加熱及加壓時,將平台42及壓接頭41中的至少一個加熱至比形成作為半導體晶片1的連接部的凸塊30的表面的金屬材料的熔點、及形成作為基板2的連接部的配線16的表面的金屬材料的熔點更低的溫度。
於將基板2暫時壓接於半導體晶片1上的步驟中,為了於拾取半導體晶片時不使熱朝半導體晶片等傳遞,較佳為暫時壓接用按壓構件為低溫。於用於暫時壓接的加熱及加壓時,為了可排除捲入時的空隙,亦可將暫時壓接用按壓構件加熱至接著劑層的流動性提高的程度的高溫。為了縮短冷卻時間,拾取半導體晶片時的按壓構件的溫度與進行暫時壓接時的按壓構件的溫度的差可小。該溫度差可為100℃以下、或60℃以下。該溫度差亦可固定。若溫度差為100℃以下,則存在暫時壓接用按壓構件的冷卻時間縮短,生產性進一步提升的傾向。
暫時壓接用按壓構件的溫度可低於接著劑層的反應開始溫度。所謂反應開始溫度,是指使用示差掃描熱量計(Differential Scanning Calorimeter,DSC)(珀金埃爾默(PerkinElmer)公司製造,DSC-Pyirs1),於樣品量10 mg、升溫速度10℃/min、測定環境:空氣或氮氣的條件下測定由接著劑層的反應所引起的發熱時的開始(On-set)溫度。
就以上的觀點而言,平台42及/或壓接頭41的溫度於拾取半導體晶片的期間內例如可為30℃以上、130℃以下,於為了暫時壓接而對積層體3進行加熱及加壓的期間內例如可為50℃以上、150℃以下。
於為了暫時壓接而對暫時壓接用按壓構件進行加熱的溫度T(對積層體進行加熱及加壓的期間的暫時壓接用按壓構件的溫度)下,接著劑層的熔融黏度可為7000 Pa・s以下。此處,所謂「熔融黏度」,是指利用流變計(日本安東帕(Anton-Paar・Japan)股份有限公司製造,MCR301),於樣品厚度:400 μm,升溫速度10℃/min,頻率:1 Hz的條件下,使用測定夾具(可拋式板(直徑8 mm)及可拋式樣品盤)進行測定時的溫度T下的熔融狀態的接著劑層的黏度。
為了暫時壓接而對暫時壓接用按壓構件進行加熱的溫度T為接著劑層的反應開始溫度以下,亦可為接著劑層的黏度最低、樹脂容易流動的溫度。但是,若黏度過低,則存在樹脂爬上晶片側面,並附著於壓接用按壓構件上,而使生產性下降的情況。因此,於進行暫時壓接的步驟中,在為了暫時壓接而對暫時壓接用按壓構件進行加熱的溫度T下,接著劑層的熔融黏度亦可為1000 Pa・s以上。
就排除半導體晶片間或半導體晶片-基板間的空隙,使各個連接部相互充分地接觸的觀點而言,用於暫時壓接的負荷例如於半導體晶片的每1針(1個凸塊)中可為0.009 N~0.2 N。
圖2是表示藉由金屬接合來將半導體晶片的連接部與基板的連接部電性連接的正式壓接的步驟的一例的步驟圖。
如圖2的(a)及(b)所示,使用有別於按壓裝置43所準備的具有作為正式壓接用按壓構件的平台45及壓接頭44的正式壓接用的按壓裝置46,進一步對積層體3進行加熱及加壓。利用平台45及壓接頭44夾持積層體3,藉此進行加熱及加壓,由此藉由金屬接合來將凸塊30與配線16電性連接。藉此正式壓接半導體晶片1與基板2。於圖2的實施形態的情況下,壓接頭44配置於積層體3的半導體晶片1側,平台45配置於積層體3的基板2側。
於對積層體3進行加熱及加壓時,將平台45或壓接頭44中的至少一個加熱至形成作為半導體晶片1的連接部的凸塊30的表面的金屬材料的熔點、或形成作為基板2的連接部的配線16的表面的金屬材料的熔點中的至少任一個熔點以上的溫度。於連接部的金屬材料含有焊料的情況下,該加熱溫度(正式壓接中的平台45及/或壓接頭44的溫度)可為230℃以上或250℃以上,亦可為330℃以下或300℃以下。若加熱溫度為230℃以上或250℃以上,則連接部的焊料熔融而容易形成充分的金屬結合。若加熱溫度為330℃以下或300℃以下,則難以產生空隙,可進一步抑制焊料的飛散。就去除冷卻時間,提升生產性這一觀點而言,於正式壓接的步驟中,正式壓接中的溫度可固定。
於重複對多個積層體3依次進行加熱及加壓來連續地製造多個半導體裝置的期間內,可將平台45及/或壓接頭44的溫度維持成固定以上的溫度。換言之,可一面將平台45及/或壓接頭44維持成固定以上,一面依次更換積層體3來連續進行多次正式壓接。藉由將裝置維持成固定的範圍的溫度,無需冷卻時間且生產性進一步提升。有時於接觸外部氣體及半導體晶片時熱量逸散,平台45及/或壓接頭44的溫度略微變動,但只要變動的範圍為±10℃以下,則即便變動亦不存在問題。
於對積層體進行加熱及加壓時,平台45及/或壓接頭44的溫度可高於接著劑層的反應開始溫度。於正式壓接中促進接著劑層的硬化,藉此存在抑制空隙及連接性進一步提升的傾向。
暫時壓接用按壓構件及正式壓接用按壓構件可分別設置於2個以上的不同的裝置中,亦可共同設置於1個裝置內。可使用具備暫時壓接用按壓構件及正式壓接用按壓構件的雙頭型裝置。
於圖1及圖2的實施形態中表示了壓接半導體晶片與基板的步驟的例子,但製造半導體裝置的方法亦可包括將半導體晶片彼此相互壓接的步驟。亦可使用包含相當於半導體晶片1的多個部分的切割前的半導體晶圓來代替半導體晶片1。一面以凸塊的熔點以上的溫度對半導體晶片彼此進行加熱一面按壓,而將半導體晶片間連接,並且以連接部得到密封的方式,藉由接著劑膜來填充半導體晶片間的空隙。於連接部的金屬材料含有焊料的情況下,能夠以連接部(焊料部分)的溫度變成230℃以上或250℃以上的方式對半導體晶片進行加熱。連接負荷取決於凸塊數,但要考慮吸收凸塊的高度不均、及控制凸塊變形量來設定。就提升生產性的觀點而言,連接時間可設定成短時間。可一面使焊料熔融來去除氧化膜及表面的雜質,一面於連接部形成金屬接合。
就提升生產性的觀點而言,暫時壓接所耗費的壓接時間及正式壓接所耗費的連接時間(壓接時間)可設定成短時間。所謂短時間的連接時間(壓接時間),是指於連接形成(正式壓接)中將連接部加熱至230℃以上的時間(例如,使用焊料時的時間)為5秒以下。連接時間亦可為4秒以下或3秒以下。若各壓接時間比冷卻時間短,則可進一步顯現本發明的製造方法的效果。
作為暫時壓接用或正式壓接用的按壓裝置,可使用覆晶接合機、加壓烘箱等。
於暫時壓接及正式壓接中,亦可壓接多個晶片。例如於平面式地壓接多個晶片的集團接合中,可將多個半導體晶片一個一個地暫時壓接於晶圓或圖板上,其後,一次性地正式壓接多個晶片。
於在TSV結構的封裝中常見的堆疊壓接中,立體式地壓接多個晶片。於該情況下,亦可將多個半導體晶片一個一個地堆積並進行暫時壓接,其後,一次性地正式壓接多個晶片。
第二實施形態 第二實施形態的半導體裝置的製造方法亦包括如下的步驟:將半導體晶片與基板或其他半導體晶片暫時固定而獲得積層體後,利用具備平台與壓接頭的正式壓接用按壓構件進行正式壓接。將半導體晶片與基板或其他半導體晶片暫時固定而獲得積層體的步驟可為與第一實施形態的暫時壓接相同的形態。第二實施形態與第一實施形態的不同點在於利用平台及與平台對向的壓接頭夾持配置於平台上的多個積層體與以覆蓋該些積層體的方式配置的一次性連接用片材,藉此一次性對多個積層體進行加熱及加壓來進行正式壓接,其他與第一實施形態相同。圖3是表示使用一次性連接用片材,並藉由金屬接合來將半導體晶片的連接部與基板的連接部電性連接的正式壓接的步驟的一例的步驟圖。可將具有半導體晶圓與多個半導體晶片的積層體配置於平台上,並利用一次性連接用片材對其進行覆蓋。
如圖3的(a)及(b)所示,使用有別於暫時壓接用的按壓裝置43所準備的具有作為正式壓接用按壓構件的平台45及壓接頭44的正式壓接用的按壓裝置46,進一步對積層體3進行加熱及加壓。於平台45上排列多個積層體3,並以覆蓋積層體3的方式配置一次性連接用片材47。而且,利用平台45及壓接頭44同時夾持一次性連接用片材47與多個積層體3,藉此一次性對多個積層體進行加熱及加壓,由此藉由金屬接合來將凸塊30與配線16電性連接。於圖3的實施形態的情況下,壓接頭44配置於積層體3的半導體晶片1側,平台45配置於積層體3的基板2側。
就一次性地壓接更多的半導體晶片來提升半導體裝置的生產性的觀點而言,壓接頭44的與半導體晶片接觸的面的面積可為50 mm×50 mm以上。就可對應於尺寸為12吋的晶圓這一觀點而言,壓接頭44的與半導體晶片接觸的面的面積可為330 mm×330 mm左右。
<一次性連接用片材> 一次性連接用片材的原料只要是於250℃下顯示出特定的儲存彈性模數與位移量的樹脂,則並無特別限定。作為樹脂,例如可列舉:聚四氟乙烯樹脂、聚醯亞胺樹脂、苯氧基樹脂、環氧樹脂、聚醯胺樹脂、聚碳二醯亞胺樹脂、氰酸酯樹脂、丙烯酸樹脂、聚酯樹脂、聚乙烯樹脂、聚醚碸樹脂、聚醚醯亞胺樹脂、聚乙烯縮醛樹脂、胺基甲酸酯樹脂、及丙烯酸橡膠。就耐熱性及膜形成性優異這一觀點而言,一次性連接用片材可為包含選自聚四氟乙烯樹脂、聚醯亞胺樹脂、環氧樹脂、苯氧基樹脂、丙烯酸樹脂、丙烯酸橡膠、氰酸酯樹脂、及聚碳二醯亞胺樹脂中的至少一種樹脂的片材。就耐熱性及膜形成性特別優異這一觀點而言,一次性連接用片材的樹脂可為包含選自聚四氟乙烯樹脂、聚醯亞胺樹脂、苯氧基樹脂、丙烯酸樹脂及丙烯酸橡膠中的至少一種樹脂的片材。該些樹脂可單獨使用一種、或將兩種以上組合使用。
若250℃下的一次性連接用片材的儲存彈性模數低,則存在使用具有大的面積的壓接頭按壓半導體晶片時容易確保良好的連接的傾向。因此,關於250℃下的一次性連接用片材的儲存彈性模數,例如儲存彈性模數可為10 GPa以下、或8 GPa以下。若250℃下的一次性連接用片材的儲存彈性模數高,則一次性連接用片材具有適當的柔軟度,因此存在進一步吸收多個積層體間的高低差並顯現良好的平行度,可更均勻地對該些積層體進行加壓的傾向。因此,250℃下的一次性連接用片材的儲存彈性模數可為0.01 GPa以上、或0.1 GPa以上。250℃下的儲存彈性模數可使用通常的彈性模數測定裝置來測定。例如,可使用彈性模數測定裝置RSA2(流變科學(Rheometric Scientific)公司製造)等,一面以頻率10 Hz、升溫速度5℃/min自-30℃升溫至300℃為止,一面測定樣品的黏彈性,並根據其測定結果求出250℃下的儲存彈性模數。
一次性連接用片材的250℃下的儲存彈性模數滿足所述範圍,進而可顯示出250℃下的充分的位移量,例如40 μm以上。若該位移量為40 μm以上,則於一次性地正式壓接多個半導體晶片時可確保特別良好的連接。250℃下的位移量亦可為200 μm以下。於本說明書中,所謂位移量,是指於將具有直徑8 μm的圓形的端面的棒狀的按壓用治具擠壓於一次性連接片材的主面上(使主面與端面成為平行的方向)的壓縮試驗中,於250℃的環境下且壓縮負荷為100 N時的位移量。位移量例如可使用機電式萬能試驗機(英斯特朗(INSTRON)公司製造)來測定。
一次性連接用片材的耐熱性可高。就提高半導體裝置的生產性的觀點而言,一次性連接用片材可為於250℃以上的溫度下壓接時不熔融,且不附著於半導體晶片上者。
就使正式壓接用按壓構件可識別由一次性連接用片材覆蓋的半導體晶片或基板上的對準標記(用於對位的識別用標記)的觀點而言,一次性連接用片材可具有高透明性。一次性連接用片材的波長550 nm中的透過率例如可為10%以上。
一次性連接用片材的厚度能夠以滿足所述性質的方式適宜設計。厚度例如可為50 μm以上、80 μm以上、或100 μm以上。一次性連接用片材的厚度亦可為300 μm以下。
一次性連接用片材可為市售的彈性體片材。作為市售的彈性體片材,可列舉:尼特氟龍(Nitoflon)900UL(日東電工公司製造)、尤匹萊克斯(Upilex)SGA(宇部興產公司製造)等。
藉由使用具有所述特定的儲存彈性模數及位移量的一次性連接用片材,可充分地吸收多個積層體間的高低差並顯現良好的平行度,且均勻地對該些積層體進行加壓,因此任一種半導體裝置均可確保更良好的連接。另外,即便於壓接時自半導體晶片中露出的接著劑附著於一次性連接用片材上,亦容易更換,因此生產性難以下降。
第三實施形態 於第三實施形態的半導體裝置的製造方法中,緊接著與第一實施形態相同的暫時壓接,如圖4所示,於加熱爐60內對經暫時壓接的積層體3進行加熱,由此藉由金屬接合來將半導體晶片1的凸塊30與基板2的配線16電性連接。除此以外,第三實施形態的方法與第一實施形態相同。可於1個加熱爐60內對多個積層體進行加熱,而一次性進行多個積層體中的連接。
於對積層體進行加熱時,將加熱爐60內的氣體加熱至形成半導體晶片1的連接部的表面的金屬材料的熔點、或形成基板2的連接部的表面的金屬材料的熔點中的至少任一個熔點以上的溫度。
當連接部的金屬材料含有焊料時,於對積層體進行加熱的期間內,加熱爐60內的氣體的溫度可為230℃以上、330℃以下。若加熱爐60內的氣體的溫度為230℃以上,則連接部的焊料熔融而容易形成充分的金屬結合。若加熱爐60內的氣體的溫度為330℃以下,則難以產生空隙,可進一步抑制焊料的飛散。加熱爐60內的壓力並無特別限制,但可為大氣壓。
於對積層體進行加熱的期間內,加熱爐60內的氣體的溫度可高於接著劑層的反應開始溫度。於加熱步驟中促進接著劑層的硬化,藉此抑制空隙及連接性可進一步提升。
於加熱爐60內,可在將重物載置於積層體上、或利用夾具固定積層體等的狀態下,對積層體進行加熱。藉此,可進一步抑制由半導體晶片與基板之間、及半導體晶片與接著劑層之間的熱膨脹差所產生的翹曲及連接不良。
作為加熱爐,可使用回焊爐、烘箱等。或者,亦可於加熱板上對積層體進行加熱。於此情況下,加熱板的溫度可設定成與加熱爐內的空氣相同的溫度。
將連接部加以連接的步驟(加熱步驟)不僅形成金屬結合,而且可促進接著劑層的硬化。於使用壓接用按壓構件進行連接的情況下,於壓接時壓接用按壓構件的熱難以傳導至作為朝晶片側面露出的接著劑的焊點上。因此,連接後為了使焊點部分等的硬化更充分,需要進一步的加熱處理步驟。但是,當不使用壓接用按壓構件,而使用熱施加至整個積層體的回焊爐、烘箱、加熱板等時,可縮短或去除連接後的加熱處理。
<半導體裝置> 對藉由本實施形態的半導體裝置的製造方法所獲得的半導體裝置進行說明。本實施形態的半導體裝置中的連接部可為凸塊與配線的金屬接合、及凸塊與凸塊的金屬接合的任一種。於本實施形態的半導體裝置中,例如可使用經由接著劑層而獲得電性連接的覆晶連接。
圖5是表示半導體裝置的一實施形態(半導體晶片及基板的COB型的連接形態)的示意剖面圖。圖5的(a)中所示的半導體裝置100具備半導體晶片1與基板(配線電路基板)2、及介於該些之間的接著劑層40。於半導體裝置100的情況下,半導體晶片1具有半導體晶片本體10、配置於半導體晶片本體10的基板2側的面上的配線15、及配置於配線15上的作為連接部的凸塊30。基板2具有基板本體20、及配置於基板本體20的半導體晶片1側的面上的作為連接部的配線16。半導體晶片1的凸塊30與基板2的配線16藉由金屬接合而電性連接。半導體晶片1及基板2藉由配線16及凸塊30而覆晶連接。配線15、配線16及凸塊30由接著劑層40密封,藉此遠離外部環境。

圖6是表示半導體裝置的其他實施形態(半導體晶片彼此的COC型的連接形態)的示意剖面圖。除2個半導體晶片1經由配線15及凸塊30而覆晶連接這一點以外,圖6的(a)中所示的半導體裝置300的構成與半導體裝置100相同。除2個半導體晶片1經由凸塊32而覆晶連接這一點以外,圖6的(b)中所示的半導體裝置400的構成與半導體裝置200相同。
於圖5及圖6中,配線15、凸塊32等連接部可為被稱為焊墊的金屬膜(例如,鍍金),亦可為後電極(post electrode)(例如,銅柱(copper pillar))。例如,於圖6的(b)中,在一個半導體晶片具有銅柱及連接凸塊(焊料:錫-銀)作為連接部,另一個半導體晶片具有鍍金作為連接部的形態中,連接部只要達到連接部的金屬材料中的熔點最低的焊料的熔點以上的溫度,則焊料熔融並於連接部間形成金屬接合,可實現連接部間的電性連接。
作為半導體晶片本體10,並無特別限制,可使用包含矽、鍺等同一種類的元素的元素半導體,砷化鎵、銦磷等化合物半導體等各種半導體。
作為基板2,只要是配線電路基板,則並無特別限制,可使用:於將環氧玻璃、聚醯亞胺、聚酯、陶瓷、環氧樹脂(epoxy)、雙馬來醯亞胺三嗪等作為主要成分的絕緣基板的表面上將所形成的金屬層的不需要的部位蝕刻去除而形成有配線(配線圖案)的電路基板、藉由金屬鍍敷等而於所述絕緣基板的表面上形成有配線(配線圖案)的電路基板、將導電性物質印刷於所述絕緣基板的表面上而形成有配線(配線圖案)的電路基板等。
作為配線15及配線16、凸塊30、凸塊32及凸塊33(導電性突起)等連接部的材質,可使用金、銀、銅、焊料(主成分例如為錫-銀、錫-鉛、錫-鉍、錫-銅、錫-銀-銅)、錫、鎳等作為主成分,可僅包含單一的成分,亦可包含多種成分。連接部亦可具有將該些金屬積層而成的結構。金屬材料之中,銅、焊料比較廉價。就提升連接可靠性及抑制翹曲的觀點而言,連接部可含有焊料。
作為焊墊的材質,可使用金、銀、銅、焊料(主成分例如為錫-銀、錫-鉛、錫-鉍、錫-銅、錫-銀-銅)、錫、鎳等作為主成分,可僅包含單一的成分,亦可包含多種成分。焊墊亦可具有將該些金屬積層而成的結構。就連接可靠性的觀點而言,焊墊可含有金及/或焊料。
於配線15、配線16(配線圖案)的表面上可形成將金、銀、銅、焊料(主成分例如為錫-銀、錫-鉛、錫-鉍、錫-銅)、錫、鎳等作為主成分的金屬層。該金屬層可僅包含單一的成分,亦可包含多種成分。金屬層亦可具有將多個金屬層積層而成的結構。金屬層可含有比較廉價的銅及/或焊料。就提升連接可靠性及抑制翹曲的觀點而言,金屬層可含有焊料。
可將如圖5或圖6中所示的半導體裝置(封裝)積層,並藉由金、銀、銅、焊料(主成分例如為錫-銀、錫-鉛、錫-鉍、錫-銅、錫-銀-銅)、錫、鎳等來進行電性連接。用於進行連接的金屬可為比較廉價的銅及/或焊料。例如可如於TSV技術中所看到般,使接著劑層介於半導體晶片間來進行覆晶連接或積層,形成貫穿半導體晶片的孔,並與圖案面的電極相連。
圖7是表示半導體裝置的其他實施形態(半導體晶片積層型的形態(TSV))的示意剖面圖。於圖7中所示的半導體裝置500中,藉由將形成於作為基板的中介層(interposer)本體50上的配線15與半導體晶片1的凸塊30連接,而將半導體晶片1與中介層5覆晶連接。接著劑層40介於半導體晶片1與中介層5之間。在所述半導體晶片1中的與中介層5相反側的表面上,經由配線15、凸塊30及接著劑層40而重複積層有半導體晶片1。半導體晶片1的表背的圖案面的配線15藉由填充至貫穿半導體晶片本體10的內部的孔內的貫穿電極34而相互連接。作為貫穿電極34的材質,可使用銅、鋁等。
藉由此種TSV技術,亦可自通常不使用的半導體晶片的背面取得信號。進而,因使貫穿電極34於半導體晶片1內垂直地穿過,故縮短對向的半導體晶片1間、以及半導體晶片1與中介層5間的距離,並可實現柔軟的連接。於此種TSV技術中,本實施形態的接著劑層可用作對向的半導體晶片1間、以及半導體晶片1與中介層5間的密封材料。
於區域凸塊晶片技術等自由度高的凸塊形成方法中,可不經由中介層而將半導體晶片以原樣直接安裝於母板上。本實施形態的接著劑層亦可應用於將此種半導體晶片直接安裝於母板上的情況。於將2個配線電路基板積層的情況下,對基板間的空隙進行密封或填充時亦可應用本實施形態的接著劑層。
<熱硬化性樹脂組成物> 接著劑層例如可為由熱硬化性樹脂組成物所形成的層,所述熱硬化性樹脂組成物含有具有10000以下的分子量的熱硬化性樹脂及其硬化劑。換言之,接著劑層可為包含熱硬化性樹脂組成物的層,所述熱硬化性樹脂組成物含有具有10000以下的分子量的熱硬化性樹脂及其硬化劑。
(a)熱硬化性樹脂 熱硬化性樹脂為可藉由加熱而形成交聯結構的化合物。熱硬化性樹脂可具有10000以下的分子量。熱硬化性樹脂組成物藉由含有與硬化劑進行反應而形成交聯結構的化合物(熱硬化性樹脂),而抑制分子量小的成分於加熱時分解等所產生的空隙,因此就耐熱性的觀點而言有利。作為熱硬化性樹脂,可列舉:環氧樹脂、丙烯酸樹脂等。
就耐熱性、流動性的觀點而言,熱硬化性樹脂的重量平均分子量可為100~9000、或300~7000。熱硬化性樹脂的重量平均分子量的測定方法與後述的(d)高分子成分的重量平均分子量的測定方法相同。
(a1)丙烯酸樹脂 丙烯酸樹脂是於分子內具有1個以上的(甲基)丙烯醯基的化合物。作為丙烯酸樹脂,例如可列舉:具有源自選自雙酚A、雙酚F、萘、苯酚酚醛清漆、甲酚酚醛清漆、苯酚芳烷基、聯苯、三苯基甲烷、二環戊二烯、茀、金剛烷及異三聚氰酸中的化合物的骨架及(甲基)丙烯醯氧基的(甲基)丙烯酸酯,以及各種多官能(甲基)丙烯酸化合物。就耐熱性的觀點而言,可自具有源自選自雙酚A、雙酚F、萘、茀、金剛烷及異三聚氰酸中的化合物的骨架的(甲基)丙烯酸酯中選擇丙烯酸樹脂。丙烯酸樹脂可單獨使用一種、或將兩種以上組合使用。
相對於熱硬化性樹脂組成物的總量100質量份,丙烯酸樹脂的含量可為10質量份~50質量份、或15質量份~40質量份。若丙烯酸樹脂的含量為10質量%以上,則充分地存在硬化成分,因此容易控制熱硬化性樹脂組成物的硬化後的流動。若丙烯酸樹脂的含量為50質量%以下,則可進一步抑制由硬化物變得過硬所引起的封裝的翹曲。
丙烯酸樹脂於室溫(25℃)下可為固體。就難以產生空隙這一點、及硬化前(B階段)的熱硬化性樹脂組成物的黏性(黏度)小且處理性優異這一點而言,固體的丙烯酸樹脂比液狀的丙烯酸樹脂有利。作為於室溫(25℃)下為固體的丙烯酸樹脂,例如可列舉:具有源自選自雙酚A、茀、金剛烷及異三聚氰酸中的化合物的骨架的(甲基)丙烯酸酯。
丙烯酸樹脂中的(甲基)丙烯醯基的數量(官能基數)可為3以下。若官能基數為3以下,則熱硬化性樹脂組成物可於短時間內充分地硬化,因此可進一步抑制硬化反應率的下降。若硬化反應率低,則未反應基可能殘存。
(a2)環氧樹脂 環氧樹脂是於分子內具有2個以上的環氧基的化合物。作為環氧樹脂,例如可列舉:雙酚A型、雙酚F型、萘型、苯酚酚醛清漆型、甲酚酚醛清漆型、苯酚芳烷基型、聯苯型、三苯基甲烷型及二環戊二烯型環氧樹脂,以及各種多官能環氧樹脂。就耐熱性、處理性的觀點而言,可自雙酚F型、苯酚酚醛清漆型、甲酚酚醛清漆型、聯苯型、及三苯基甲烷型環氧樹脂中選擇環氧樹脂。就速硬化性及耐熱性的觀點而言,可自雙酚F型及三苯基甲烷型環氧樹脂中選擇環氧樹脂。環氧樹脂可單獨使用一種、或將兩種以上組合使用。
相對於熱硬化性樹脂組成物的總量100質量份,環氧樹脂的含量可為10質量份~50質量份。若環氧樹脂的含量為10質量份以上,則充分地存在硬化成分,因此容易控制熱硬化性樹脂組成物的硬化後的流動。若環氧樹脂的含量為50質量份以下,則可進一步抑制由硬化物變得過硬所引起的封裝的翹曲。
(b)硬化劑 硬化劑是與熱硬化性樹脂進行反應,並與熱硬化性樹脂一同形成交聯結構的化合物。作為硬化劑,例如可列舉:酚樹脂系硬化劑、酸酐系硬化劑、胺系硬化劑、咪唑系硬化劑、膦系硬化劑、偶氮化合物及有機過氧化物。硬化反應(硬化系)可為自由基聚合(自由基聚合系)。硬化劑可單獨使用一種、或將兩種以上組合使用。酚樹脂系硬化劑、酸酐系硬化劑及胺系硬化劑分別可單獨使用一種、或用作兩種以上的混合物。咪唑系硬化劑及膦系硬化劑分別可單獨使用,但亦可與酚樹脂系硬化劑、酸酐系硬化劑或胺系硬化劑一同使用。
只要硬化進行,則熱硬化性樹脂與硬化劑的組合並無特別限制。就處理性及保存穩定性的觀點而言,與丙烯酸樹脂進行組合的硬化劑可為有機過氧化物。就處理性、保存穩定性及硬化性優異的觀點而言,與環氧樹脂進行組合的硬化劑可自酚樹脂系硬化劑與咪唑系硬化劑、酸酐系硬化劑與咪唑系硬化劑、胺系硬化劑與咪唑系硬化劑、及僅咪唑系硬化劑中選擇。若於短時間內硬化,則生產性提升,因此可單獨使用速硬化性及保存穩定性優異的咪唑系硬化劑。若熱硬化性樹脂組成物於短時間內硬化,則可減少低分子成分等揮發成分的量,因此可進一步抑制空隙的產生。就處理性、保存穩定性的觀點而言,與丙烯酸樹脂進行組合的硬化劑可為有機過氧化物或偶氮化合物。
(b1)酚樹脂系硬化劑 酚樹脂系硬化劑於分子內具有2個以上的酚性羥基。作為酚樹脂系硬化劑,例如可列舉:苯酚酚醛清漆、甲酚酚醛清漆、苯酚芳烷基樹脂、甲酚萘酚甲醛縮聚物、三苯基甲烷型多官能苯酚及各種多官能酚樹脂。該些可單獨使用一種、或將兩種以上組合使用。
就硬化性、接著性及保存穩定性優異的觀點而言,酚樹脂系硬化劑對於環氧樹脂的當量比(酚性羥基/環氧基,莫耳比)可為0.3~1.5、0.4~1.0、或0.5~1.0。若該當量比為0.3以上,則存在硬化性提升且接著力進一步提升的傾向。若該當量比為1.5以下,則存在未反應的酚性羥基不過度地殘存,吸水率被抑制得低,絕緣可靠性進一步提升的傾向。
(b2)酸酐系硬化劑 作為酸酐系硬化劑,例如可列舉:甲基環己烷四羧酸二酐、偏苯三甲酸酐、均苯四甲酸酐、二苯甲酮四羧酸二酐及乙二醇雙脫水偏苯三酸酯。該些可單獨使用一種、或將兩種以上組合使用。

(b3)胺系硬化劑 作為胺系硬化劑,例如可列舉:二氰二胺、十二烷二胺等。該些可單獨使用一種、或將兩種以上組合使用。
就硬化性、接著性及保存穩定性優異的觀點而言,胺系硬化劑對於環氧樹脂的當量比(胺基的活性氫數/環氧基,莫耳比)可為0.3~1.5、0.4~1.0、或0.5~1.0。若該當量比為0.3以上,則存在硬化性提升且接著力進一步提升的傾向。若該當量比為1.5以下,則未反應的胺難以過度地殘存,因此存在絕緣可靠性提升的傾向。
(b4)咪唑系硬化劑 作為咪唑系硬化劑,例如可列舉:2-苯基咪唑、2-苯基-4-甲基咪唑、1-苄基-2-甲基咪唑、1-苄基-2-苯基咪唑、1-氰基乙基-2-十一基咪唑、1-氰基-2-苯基咪唑、1-氰基乙基-2-十一基咪唑偏苯三酸酯、1-氰基乙基-2-苯基咪唑鎓偏苯三酸酯、2,4-二胺基-6-[2'-甲基咪唑基-(1')]-乙基-均三嗪、2,4-二胺基-6-[2'-十一基咪唑基-(1')]-乙基-均三嗪、2,4-二胺基-6-[2'-乙基-4'-甲基咪唑基-(1')]-乙基-均三嗪、2,4-二胺基-6-[2'-甲基咪唑基-(1')]-乙基-均三嗪異三聚氰酸加成物、2-苯基咪唑異三聚氰酸加成物、2-苯基-4,5-二羥基甲基咪唑、2-苯基-4-甲基-5-羥基甲基咪唑、及環氧樹脂與咪唑類的加成物。就硬化性、保存穩定性及連接可靠性優異的觀點而言,可自1-氰基乙基-2-十一基咪唑、1-氰基-2-苯基咪唑、1-氰基乙基-2-十一基咪唑偏苯三酸酯、1-氰基乙基-2-苯基咪唑鎓偏苯三酸酯、2,4-二胺基-6-[2'-甲基咪唑基-(1')]-乙基-均三嗪、2,4-二胺基-6-[2'-乙基-4'-甲基咪唑基-(1')]-乙基-均三嗪、2,4-二胺基-6-[2'-甲基咪唑基-(1')]-乙基-均三嗪異三聚氰酸加成物、2-苯基咪唑異三聚氰酸加成物、2-苯基-4,5-二羥基甲基咪唑及2-苯基-4-甲基-5-羥基甲基咪唑中選擇咪唑系硬化劑。該些可單獨使用一種、或將兩種以上組合使用。另外,亦可用作將該些加以微膠囊化而成的潛在性硬化劑。
相對於環氧樹脂100質量份,咪唑系硬化劑的含量可為0.1質量份~20質量份、或0.1質量份~10質量份。若該含量為0.1質量份以上,則存在硬化性提升的傾向。若該含量為20質量份以下,則於形成金屬接合前熱硬化性樹脂組成物難以硬化,因此存在難以產生連接不良的傾向。
(b5)膦系硬化劑 作為膦系硬化劑,例如可列舉:三苯基膦、四苯基鏻四苯基硼酸鹽、四苯基鏻四(4-甲基苯基)硼酸鹽及四苯基鏻(4-氟苯基)硼酸鹽。該些可單獨使用一種、或將兩種以上組合使用。
相對於環氧樹脂100質量份,膦系硬化劑的含量可為0.1質量份~10質量份、或0.1質量份~5質量份。若該含量為0.1質量份以上,則存在硬化性提升的傾向。若該含量為10質量份以下,則於形成金屬接合前熱硬化性樹脂組成物難以硬化,因此存在難以產生連接不良的傾向。
(b6)偶氮化合物 作為偶氮化合物,例如可列舉:二甲基胺基偶氮苯、二甲基胺基偶氮苯-羧酸、二乙基胺基偶氮苯、及二乙基胺基偶氮苯-羧酸。偶氮化合物可單獨使用一種、或將兩種以上組合使用。
相對於丙烯酸樹脂100質量份,偶氮化合物的含量可為0.5質量份~10質量份、或1質量份~5質量份。若該含量為0.5質量%以上,則存在硬化性提升的傾向。若該含量為10質量份以下,則於形成金屬接合前熱硬化性樹脂組成物難以硬化,因此存在難以產生連接不良的傾向。
(b7)有機過氧化物 作為有機過氧化物,例如可列舉:酮過氧化物、過氧縮酮、氫過氧化物、二烷基過氧化物、二醯基過氧化物、過氧化二碳酸酯、過氧酯等。就保存穩定性的觀點而言,有機過氧化物可為選自氫過氧化物、二烷基過氧化物及過氧酯中的一種以上。就耐熱性的觀點而言,有機過氧化物可為選自氫過氧化物及二烷基過氧化物中的一種以上。該些可單獨使用一種、或將兩種以上組合使用。
相對於丙烯酸樹脂100質量份,有機過氧化物的含量較佳為0.5質量份~10質量份,更佳為1質量份~5質量份。若該含量為0.5質量%以上,則存在硬化性提升的傾向。若該含量為10質量份以下,則於形成金屬接合前熱硬化性樹脂組成物難以硬化,因此存在難以產生連接不良的傾向。另外,若該含量過少,則硬化急劇地進行且反應點變多,因此存在難以產生由分子鏈變短、或未反應基殘存所引起的可靠性的下降的傾向。
(c)高分子成分 本實施形態的熱硬化性樹脂組成物可進而含有具有10000以上的重量平均分子量的高分子成分。熱硬化性樹脂、硬化劑等高分子成分以外的成分的重量平均分子量或分子量通常未滿10000。作為高分子成分,例如可列舉:環氧樹脂、苯氧基樹脂、聚醯亞胺樹脂、聚醯胺樹脂、聚碳二醯亞胺樹脂、氰酸酯樹脂、丙烯酸樹脂、聚酯樹脂、聚乙烯樹脂、聚醚碸樹脂、聚醚醯亞胺樹脂、聚乙烯縮醛樹脂、胺基甲酸酯樹脂及丙烯酸橡膠。就耐熱性及膜形成性優異這一觀點而言,可自環氧樹脂、苯氧基樹脂、聚醯亞胺樹脂、丙烯酸樹脂、丙烯酸橡膠、氰酸酯樹脂及聚碳二醯亞胺樹脂中選擇高分子量成分。就耐熱性及膜形成性更優異這一觀點而言,可自環氧樹脂、苯氧基樹脂、聚醯亞胺樹脂、丙烯酸樹脂及丙烯酸橡膠中選擇高分子量成分。該些高分子成分可單獨使用一種、或將兩種以上組合使用。
高分子成分與丙烯酸樹脂的質量比並無特別限制。相對於高分子成分1質量份,丙烯酸樹脂的含量可為0.01質量份~10質量份、0.05質量份~5質量份、或0.1質量份~5質量份。若該質量比為0.01質量份以上,則存在硬化性提升且接著力進一步提升的傾向。若該質量比為10質量份以下,則存在熱硬化性樹脂組成物的膜形成性特別優異的傾向。
高分子成分與環氧樹脂的質量比並無特別限制。相對於高分子成分1質量份,環氧樹脂的含量可為0.01質量份~5質量份、0.05質量份~4質量份、或0.1質量份~3質量份。若該質量比為0.01質量份以上,則存在硬化性提升且接著力進一步提升的傾向。若該質量比為5質量份以下,則存在熱硬化性樹脂組成物的膜形成性特別優異的傾向。
就熱硬化性樹脂組成物朝基板及晶片上的貼附性優異的觀點而言,高分子成分的玻璃轉移溫度(Tg)可為120℃以下、100℃以下、或85℃以下。高分子量成分的Tg亦可為0℃以上。若高分子成分的Tg為120℃以下,則容易將形成於半導體晶片上的凸塊、形成於基板上的電極或配線圖案等的高低差埋入至熱硬化性樹脂組成物中,因此存在氣泡的殘存得到抑制且難以產生空隙的傾向。於本說明書中,所謂Tg,是指使用DSC(珀金埃爾默公司製造的DSC-7型),並藉由利用樣品量10mg、升溫速度10℃/min、測定環境:空氣的條件的示差掃描熱量測定所求出的值。
高分子成分的重量平均分子量以聚苯乙烯換算計可為10000以上,但為了單獨顯示出更良好的膜形成性,亦可為30000以上、40000以上、或50000以上。於本說明書中,所謂重量平均分子量,是指使用高效液相層析法(島津製作所製造的C-R4A)所測定的聚苯乙烯換算的重量平均分子量。
(d)填料
為了控制黏度及硬化物的物性,及為了進一步抑制將半導體晶片彼此、或半導體晶片與基板連接時的空隙的產生及吸濕率,本實施形態的熱硬化性樹脂組成物可進而含有填料。作為填料,例如可列舉:無機填料及樹脂填料。作為無機填料,例如可列舉:玻璃、二氧化矽、氧化鋁、氧化鈦、碳黑、雲母及氮化硼等絕緣性無機填料。就處理性的觀點而言,可自二氧化矽、氧化鋁、氧化鈦及氮化硼中選擇無機填料,就形狀統一性(處理性)的觀點而言,可自二氧化矽、氧化鋁及氮化硼中選擇無機填料。絕緣性無機填料亦可為晶鬚。作為晶鬚,例如可列舉:硼酸鋁、鈦酸鋁、氧化鋅、矽酸鈣、硫酸鎂及氮化硼。作為樹脂填料,例如可列舉:聚胺基甲酸酯、聚醯亞胺、甲基丙烯酸甲酯樹脂及甲基丙烯酸甲酯-丁二烯-苯乙烯共聚樹脂(Methylmethacrylate-Butadiene-Styrene,MBS)。填料可單獨使用一種、或將兩種以上組合使用。填料的形狀、粒徑、及含量並無特別限制。
就絕緣可靠性優異的觀點而言,填料可為絕緣性。本實施形態的熱硬化性樹脂組成物可實質上不含銀填料、焊料填料等導電性的金屬填料。例如,以熱硬化性樹脂組成物的固體成分(溶媒以外的成分)整體為基準,導電性的金屬填料的含量可未滿1質量%。
填料可藉由表面處理來適宜調整物性。就提升分散性及接著力的觀點而言,填料可為經表面處理的填料。作為表面處理劑,可列舉:縮水甘油基系(環氧系)、胺系、苯基系、苯基胺基系、(甲基)丙烯酸系、乙烯基系的化合物等。
作為表面處理,就表面處理的容易性而言,較佳為利用環氧基矽烷系、胺基矽烷系、丙烯酸矽烷系等的矽烷化合物的矽烷處理。就分散性、流動性、接著力優異這一觀點而言,表面處理劑可為選自縮水甘油基系、苯基胺基系、丙烯酸系及甲基丙烯酸系的化合物中的化合物。就保存穩定性的觀點而言,表面處理劑可為選自苯基系、丙烯酸系及甲基丙烯酸系的化合物中的化合物。
就防止覆晶連接時的齧入的觀點而言,填料的平均粒徑可為1.5 μm以下。就視認性(透明性)優異這一觀點而言,填料的平均粒徑可為1.0 μm以下。填料的粒徑是指粒子的長軸徑。
與無機填料相比,樹脂填料可於260℃等的高溫下賦予柔軟性,因此適合於提升耐回焊性。另外,樹脂填料因可賦予柔軟性,故亦有助於提升熱硬化性樹脂組成物的膜形成性。
以熱硬化性樹脂組成物的固體成分(溶媒以外的成分)整體為基準,填料的含量可為30質量%~90質量%、或40質量%~80質量%。若該含量為30質量%以上,則熱硬化性樹脂組成物的散熱性變高,另外,可進一步抑制空隙產生及吸濕率。若該含量為90質量%以下,則可抑制由黏度變高所引起的熱硬化性樹脂組成物的流動性的下降、及填料朝連接部的齧入(混入),因此存在連接可靠性進一步提升的傾向。
(e)助熔劑 本實施形態的熱硬化性樹脂組成物可進而含有助熔劑(即,顯示出助熔活性(去除氧化物及雜質的活性)的助熔活性劑)。作為助熔劑,例如可列舉:咪唑類及胺類等具有非共用電子對的含氮化合物、羧酸類、酚類及醇類。與醇等相比,有機酸(2-甲基戊二酸等羧酸等)強烈地顯現助熔活性,可進一步提升連接性及穩定性。
以熱硬化性樹脂組成物的固體成分(溶媒以外的成分)整體為基準,助熔劑的含量可為0.005質量%~10.0質量%或0.005質量%~0.05質量%。
本實施形態的熱硬化性樹脂組成物可進而含有離子捕捉劑、抗氧化劑、矽烷偶合劑、鈦偶合劑、調平劑等添加劑。添加劑可單獨使用一種、或將兩種以上組合使用。添加劑的含量只要以各添加劑的效果顯現的方式適宜調整即可。
將本實施形態的熱硬化性樹脂組成物於200℃下保持5秒時的硬化反應率可為80%以上、或90%以上。若於作為焊料熔融溫度以下的200℃下保持5秒時的熱硬化性樹脂組成物的硬化反應率為80%以上,則存在焊料於焊料熔融溫度以上的連接時的溫度下難以飛散及流動,連接可靠性及絕緣可靠性進一步提升的傾向。硬化反應率可藉由對加入至鋁盤中的未硬化及熱處理後的熱硬化性樹脂組成物(膜狀接著劑)10 mg進行示差掃描熱量測定來求出,所述示差掃描熱量測定使用DSC(珀金埃爾默公司製造的DSC-7型),且升溫速度為20℃/min、溫度範圍為30℃~300℃。例如於示差掃描熱量測定中,將未處理的樣品的發熱量ΔH(J/g)設為「ΔH1」,將於加熱板上進行200℃/5秒的熱處理後的樣品的發熱量ΔH(J/g)設為「ΔH2」,並藉由下式來算出硬化反應率。 硬化反應率(%)=(ΔH1-ΔH2)/ΔH1×100
當熱硬化性樹脂組成物的硬化反應(硬化系)為自由基聚合時,若熱硬化性樹脂組成物含有陰離子聚合性的環氧樹脂(特別是重量平均分子量未滿10000的環氧樹脂),則存在難以將硬化反應率調整成80%以上的情況。當熱硬化性樹脂組成物含有丙烯酸樹脂及環氧樹脂時,相對於丙烯酸樹脂80質量份,環氧樹脂的含量可為20質量份以下。
本實施形態的熱硬化性樹脂組成物可用於200℃以上的高溫下的壓接。另外,於使焊料等金屬熔融而形成連接的覆晶封裝中,顯現更優異的硬化性。
就生產性提升的觀點而言,本實施形態的接著劑層可為由事先準備的接著劑膜所形成的層。以下表示接著劑膜的製作方法的例子。
首先,視需要將熱硬化性樹脂、硬化劑、高分子成分、填料、其他添加劑等添加至有機溶媒中後,藉由攪拌混合、混練等來進行溶解或分散而製備樹脂清漆。繼而,使用刮刀式塗佈機、輥塗機、敷料器、模塗機、缺角輪塗佈機等將樹脂清漆塗佈於實施了脫模處理的基材膜上後,藉由加熱來減少有機溶媒,而於基材膜上形成接著劑膜。亦可利用於藉由加熱來減少有機溶媒前,將樹脂清漆旋塗於晶圓等上來形成膜後,進行溶媒乾燥的方法,而於晶圓上形成接著劑膜。
作為基材膜,只要是具有可經得起使有機溶媒揮發時的加熱條件的耐熱性者,則並無特別限制,可列舉:聚酯膜、聚丙烯膜、聚對苯二甲酸乙二酯膜、聚醯亞胺膜、聚醚醯亞胺膜、聚醚萘二甲酸酯膜、甲基戊烯膜等。作為基材膜,並不限於包含該些膜中的一種的單層的膜,亦可為包含兩種以上的膜的多層膜。
用於使有機溶媒自塗佈後的樹脂清漆中揮發的加熱的條件例如可為50℃~200℃、0.1分鐘~90分鐘的範圍。若對安裝後的空隙及黏度調整無影響,則可將加熱條件設為有機溶媒揮發至1.5%以下為止的條件。
<半導體用接著劑>
一實施形態的半導體用接著劑含有(a')重量平均分子量未滿10000的樹脂成分、(b)硬化劑、及(f)由下述通式(1):[化2]
Figure 02_image003
所表示的矽烷醇化合物。式中,R1 表示烷基、苯基或包含該些的組合的基,R2 表示伸烷基。於所述半導體裝置的製造方法中,為了形成接著劑層,亦可將該半導體用接著劑用作熱硬化性樹脂組成物。
本實施形態的半導體用接著劑可進而含有(c)重量平均分子量為10000以上的高分子成分、助熔劑、填料等。以下,對各成分進行說明。
(a')重量平均分子量未滿10000的樹脂成分 作為(a')重量平均分子量未滿10000的樹脂成分,並無特別限制,但可為與(b)硬化劑進行反應的化合物(熱硬化性樹脂)。重量平均分子量小的成分於加熱時分解等而可能成為空隙的原因,但藉由該成分與硬化劑進行反應,容易確保高耐熱性。作為(a)重量平均分子量未滿10000的樹脂成分,例如可列舉:環氧樹脂、丙烯酸樹脂等。當(a')重量平均分子量未滿10000的樹脂成分為熱硬化性樹脂時,可為與所述「(a)熱硬化性樹脂」相同的形態。
關於半導體接著劑的(d)硬化劑及其他形態可為與關於所述熱硬化性樹脂組成物的「(d)硬化劑」及其他形態相同的形態。
(f)矽烷醇化合物 就耐熱性的觀點而言,由所述通式(1)所表示的矽烷醇化合物於25℃下可為固體。就耐熱性、流動性的觀點而言,式(1)中的R1 可為烷基或苯基。R1 亦可為包含烷基與苯基的組合的基(烷基取代苯基或苯基烷基)。作為由R1 所表示的基,例如可列舉:苯基、丙基、苯基丙基、及苯基甲基。式(1)中的R2 並無特別限制,但就耐熱性的觀點而言,可為重量平均分子量為100~5000的伸烷基。R2 為重量平均分子量為100~5000的伸烷基的矽烷醇化合物通常具有約100~5000的範圍的重量平均分子量。就高反應性(硬化物強度)的觀點而言,矽烷醇化合物可為三官能矽烷醇。
藉由向半導體用接著劑中添加(f)矽烷醇化合物,流動性提升且空隙抑制性與高連接性進一步提升。若流動性提升(黏度下降),則於晶片接觸時容易排除捲入的空隙。(f)矽烷醇化合物具有高耐熱性,其熱重量減少量小。藉由使用耐熱性高的矽烷醇化合物,可進一步抑制空隙產生。若熱重量減少量小,則揮發成分少,因此空隙減少,可靠性(耐回焊性)亦進一步提升。
以半導體用接著劑(溶媒以外的成分)的總量為基準,(f)矽烷醇化合物的含量可為2質量%~20質量%,就高流動化與硬化物強度(接著力等)的觀點而言,亦可為2質量%~10質量%、或2質量%~9質量%。若該含量為2質量%以上,則就高流動化的觀點而言容易顯現更顯著的效果。若該含量為20質量%以下,則存在硬化後的強度增加且顯現特別高的接著力的傾向。推測若(f)矽烷醇化合物的含量小至某種程度,則環氧樹脂或丙烯酸樹脂的硬化物的比率變大,因此顯現更高的接著力。
半導體用接著劑可為膜狀,即接著劑膜。除樹脂清漆含有(f)矽烷醇化合物這一點以外,膜狀的半導體接著劑可藉由與所述接著劑膜的製作方法的例子相同的方法來製作。
本實施形態的半導體用接著劑例如於半導體晶片及配線電路基板各自的連接部相互電性連接的半導體裝置、或多個半導體晶片各自的連接部相互電性連接的半導體裝置中,可特別適宜地用於連接部的密封。
對使用本實施形態的半導體用接著劑的半導體裝置進行說明。半導體裝置中的連接部可為凸塊與配線的金屬接合、及凸塊與凸塊的金屬接合的任一種。於半導體裝置中,例如可使用經由半導體用接著劑而獲得電性連接的覆晶連接。半導體裝置的例子如圖4~圖7所示般。連接是於所述凸塊-凸塊間、凸塊-焊墊間、凸塊-配線間進行。
本實施形態的半導體裝置的製造方法可包括使用本實施形態的半導體用接著劑,將半導體晶片及配線電路基板、或多個半導體晶片彼此連接。本實施形態的半導體裝置的製造方法例如具備:經由半導體用接著劑而將半導體晶片及配線電路基板相互連接,並且將半導體晶片及配線電路基板各自的連接部相互電性連接而獲得半導體裝置的步驟,或經由半導體用接著劑而將多個半導體晶片相互連接,並且將多個半導體晶片各自的連接部相互電性連接而獲得半導體裝置的步驟。
於本實施形態的半導體裝置的製造方法中,可藉由金屬接合而將連接部相互連接。即,藉由金屬接合而將半導體晶片及配線電路基板各自的連接部相互連接、或藉由金屬接合而將多個半導體晶片各自的連接部相互連接。
於所述第一實施形態、第二實施形態或第三實施形態的半導體裝置中,本實施形態的半導體用接著劑亦可用作熱硬化性樹脂組成物。本實施形態的半導體用接著劑於高溫下具有高流動性,因此於使用加熱爐或加熱板作為用於正式壓接的加熱裝置的第三實施形態中特別有用。
作為使用本實施形態的半導體用接著劑的半導體裝置的製造方法的另一例,對圖8中所示的實施形態的半導體裝置600的製造方法進行說明。半導體裝置600中,具有基板本體20及作為連接部的配線(銅配線)15的基板(例如環氧玻璃基板)2與具有半導體晶片本體10、作為連接部的配線(例如銅柱、銅桿)15及凸塊30(連接凸塊、焊料凸塊)的半導體晶片1經由由半導體用接著劑所形成的接著劑層40而相互連接。半導體晶片1的配線15與基板2的配線15藉由凸塊30(連接凸塊、焊料凸塊)而電性連接。於基板本體20中的形成有配線15的表面上,除凸塊30的形成位置以外配置有阻焊劑70。對基板2中的配線15實施了鍍金。連接部的金屬為焊料(錫-銀)-金,只要熔點低的焊料達到熔點以上,便可連接。半導體裝置600可為將半導體晶片彼此連接而成者。即,可將其他半導體晶片代替基板2來與半導體晶片1連接。
於半導體裝置600的製造方法中,首先,將作為接著劑層40的半導體用接著劑(膜狀接著劑等)貼附於形成有阻焊劑70的基板2上。貼附可藉由加熱壓製、輥層壓、真空層壓等來進行。接著劑層40的供給面積及厚度根據半導體晶片1或基板2的尺寸、凸塊高度等而適宜設定。接著劑層40可貼附於半導體晶片1上,亦可於將本實施形態的半導體用接著劑貼附於半導體晶圓上後,藉由切割來將半導體晶圓個片化成半導體晶片1,藉此製作貼附有接著劑層40的半導體晶片1。將接著劑層40貼附於基板2或半導體晶片1上後,使用覆晶接合機等連接裝置(壓接裝置)將半導體晶片1的配線15上的凸塊30與基板2的配線15對位後,進行壓接(第一步驟,暫時壓接),然後將半導體晶片1與基板2加熱至凸塊30的熔點以上的溫度(第二步驟,正式壓接),而將半導體晶片1與基板2連接,並且以連接部得到密封的方式,藉由接著劑層40來填充半導體晶片1與基板2之間的空隙。正式壓接(正式連接步驟,第二步驟)只要以任一側的連接部的金屬變成熔點以上的方式進行即可。當凸塊30含有焊料時,能夠以凸塊30的溫度變成250℃以上的方式對半導體晶片1與基板2進行加熱。
暫時壓接(第一步驟)的連接負荷取決於凸塊數,但要考慮吸收凸塊的高度不均、控制凸塊變形量來設定。於暫時壓接(第一步驟)後,半導體晶片1與基板2間的連接部金屬亦可接觸。若於第一步驟中連接部金屬接觸或連接,則於第二步驟後容易形成金屬結合、及半導體用接著劑的齧入變少,因此特別容易獲得良好的連接性。
於暫時壓接(第一步驟)時,為了排除空隙,且半導體晶片1與基板2間的連接部金屬接觸或形成金屬結合,可增大負荷。若負荷大,則容易排除空隙,連接部的金屬亦容易接觸。負荷例如於半導體晶片的每1針(1個凸塊)中可為0.009 N~0.3 N。
就提升生產性的觀點而言,暫時壓接(第一步驟)可設為短時間。例如,暫時壓接的時間可為5秒以下,就提升生產性的觀點而言,亦可為3秒以下、或2秒以下。
暫時壓接(第一步驟)的溫度(壓接裝置的溫度)可低至壓接工具拾取(帶有半導體用接著劑的)半導體晶片時熱不會傳遞的程度。藉由將暫時壓接(第一步驟)的溫度(壓接裝置的溫度)設為高溫,能夠以可排除捲入時的空隙的方式提高半導體用接著劑的流動性。暫時壓接(第一步驟)的溫度(壓接裝置的溫度)可低於半導體用接著劑的反應開始溫度。為了縮短冷卻時間,可減小壓接工具拾取半導體晶片時的溫度與半導體晶片彼此或半導體晶片-基板間的接觸時(暫時壓接時)的溫度的差。該溫度差可為100℃以下或60℃以下,亦可固定(相同的設定溫度)。若溫度差為100℃以下,則壓接工具的冷卻所需的時間變短,生產性進一步提升。所謂反應開始溫度,是指使用DSC(珀金埃爾默公司製造,DSC-Pyirs1),並利用樣品量10 mg、升溫速度10℃/min、測定環境:空氣或氮氣環境的條件的示差掃描熱量測定中的開始(On-set)溫度。
正式壓接(第二步驟)中的加熱溫度必須將焊料的熔點以上的溫度施加至封裝。例如,若連接部的金屬為焊料,則較佳為230℃以上、330℃以下。若為低溫,則連接部的金屬不熔融,而不形成充分的金屬結合。若為高溫,則容易產生空隙,焊料容易飛散。
為了不僅形成金屬結合,而且促進半導體用接著劑的硬化,正式壓接(正式連接步驟、第二步驟)中的加熱溫度可高於半導體用接著劑的反應開始溫度。於正式連接步驟中促進半導體用接著劑的硬化,藉此可特別有效地抑制進一步的空隙產生及連接不良。
正式壓接的加熱(第二步驟)並無特別限制,例如可使用回焊爐、烘箱、加熱板等加熱裝置來進行。作為加熱裝置,例如可列舉:回焊爐(田村製作所(Tamura Corporation)製造)及潔淨烘箱(愛斯佩克(ESPEC)製造)等。
於正式壓接(第二步驟)中,於晶片-晶片、晶片-基板、晶片-晶圓、晶圓-晶圓等的連接的情況下,可將重物載置於該些之上,亦可利用夾具夾持該些。藉此,可更有效地抑制由半導體晶片間或半導體晶片與半導體用接著劑間的熱膨脹差所產生的翹曲及連接不良。
當使用壓接機進行正式連接步驟(第二步驟)時,於壓接時壓接機的熱難以傳導至作為朝晶片側面露出的半導體用接著劑的焊點上。因此,有時於第二步驟後需要用以使焊點部分等半導體用接著劑的硬化變得充分的加熱處理。另一方面,若為了正式壓接(第二步驟)的加熱而使用如回焊爐、烘箱般的加熱爐,或加熱板等來進行,則可將熱整體地施加至被加熱體上,因此可縮短或去除第二步驟後的加熱處理。
於暫時壓接(第一步驟)中,可一次性壓接多個晶片。於在TSV結構的封裝中常見的堆疊壓接中,立體式地壓接多個晶片。於該情況下,亦可於將多個半導體晶片一個一個地堆積並進行暫時壓接的第一步驟後,於第二步驟中一次性地正式壓接多個晶片。 [實施例]
以下,列舉實施例來更具體地說明本發明。但是,本發明並不限定於以下的實施例。
