Description
本發明係關於一種感光樹脂組成物及其所製備形成之乾膜。尤其是,本發明係關於一種感光樹脂組成物,其可於低溫下固化以提供製程安全性與操作便利性,使其具有絕佳的耐彎曲性、耐焊接性、及填充圖案的特性,與絕佳的耐熱性與機械性質;以及由其製備之乾膜。
由於聚亞醯胺及其前驅物具有絕佳的持久性、耐熱性、阻燃性、以及機械與電子性質,因此,聚亞醯胺及其前驅物可優先做成印刷電路板的基底膜,並廣泛地與半導體裝置或多層電路板之覆蓋膜結合。
近年來,為了提升電路圖案的平坦性與位置精確度,係使用黃光顯影製程(photolithography process)製作電路板的感光樹脂保護膜(光成像覆蓋膜)。用於電路板的感光保護膜應滿足一些必要的條件,如:絕佳的持久性、耐熱性、阻燃性、以及機械與電子性質。
通常,會在銅箔積層板(CCL)上,使用熱壓縮一液體或熱壓縮感光樹脂組成物膜的型態,沿著圖案進行紫外光曝光、再以顯影劑進行顯影、清洗、乾燥、並且進行熱固化反應,以製備用於電路板的感光保護膜。之後,即可精確地在預定的位置上形成連接至一電路所需精密孔洞。
用於電路板感光保護膜中使用的感光樹脂組成物,可利用傳統領域中製作亁膜的方式,藉由在環氧樹脂(epoxy resin)中加入丙烯酸酯(acrylate)獲得。然而,由於使用此方法製作的固化樹脂之熱阻性低,此樹脂可於焊接製程中變色並且從電路中分離。此外,此種樹脂因缺乏彈性與耐彎曲性,亦無法使用於重覆摺疊的部份。因此,包含丙烯酸酯與環氧樹脂的組成物,用於電路板僅可限於利用軟的感光保護膜。
為了解決這些問題,亟需一有高熱阻性、耐彎曲性、與良好的介電性質的聚醯亞胺感光樹脂,作為用於電路圖案的傳統保護膜。然而,用於電路板保護膜的感光樹脂組成物中,最重要的問題是其需於高溫製程中進行。
應用於製作聚醯亞胺感光樹脂,係使用一個聚醯亞胺前驅物的聚醯胺酸增加其成形性,並使其易於表達感光性;此外,聚醯胺酸的聚醯亞胺化之固化製程通常需於300至350℃或以上之溫度進行,或250℃或以上之溫度下進行固化。
在製備印刷電路板(PCB)的製程中,考量到銅電路的氧化與退化問題,係於200℃或以下之溫度將保護膜塗佈或積層於具有圖案的銅上,然而,聚醯胺酸需於高於250℃或以上之高溫下進行固化製程變成一種限制。因此,目前亟需一種新方法以降低固化階段所需之溫度。
本發明提供一種感光樹脂組成物,其可於低溫下固化以提供製程安全性與操作便利性,使其具有絕佳的彈性、抗焊接性及填充圖案之特性,並且具有絕佳的耐熱性與機械性質。
此外,本發明提供一種乾膜,此乾膜係包含上述之感光樹脂組成物之一固化樹脂產物。
再者,本發明提供一種多層印刷電路板、一種軟性印刷電路板、一種可撓式印刷電路板以及一種用於半導體之積層板。
本發明提供一種感光樹脂組成物,包括:包含一特定重複單元之聚醯胺酸;一雜環胺化合物;一丙烯酸甲酯基化合物;一丙烯酸甲酯基化合物,其碳原子間係包含一個以上之雙鍵;一光起始劑;以及一有機溶劑。
此外,本發明提供一種乾膜,此乾膜係包含上述之感光樹脂組成物之一固化樹脂產物。
再者,本發明提供一種多層印刷電路板、一種軟性印刷電路板、一種可撓式印刷電路板以及一種用於半導體之積層板。
之後,將於特定實施例中,更詳盡地描述一種感光樹脂組成物,以及包含由其製備之固化樹脂產物的乾膜與多層印刷電路板。
本發明係搭配一實施例提供一感光樹脂組成物,其感光樹脂組成物係包含:一聚醯胺酸(polyamic acid),此聚醯胺酸包含一重複單元,此重複單元係如化學式1所示;一雜環胺化合物,此雜環胺化合物係選自以下所組成之群組:吡啶(pyridine)、三唑(triazole)、咪唑(imidazole)、喹啉(quinoline)、以及三吖嗪(triazine),且此雜環胺化合物係未取代或由至少一官能基取代,其官能基係選自以下所組成之群組:一烷基(alkyl group)、一羥基(hydroxyl group)、及一肟-衍生基團(oxime-derivative group);一丙烯酸甲酯基化合物((metha)acrylate-based compound),此丙烯酸甲酯基化合物之碳原子間係包含一個或以上之雙鍵;一光起始劑;以及一有機溶劑。
於化學式1中,X1
係為一四價有機基團,且X2
係為包含一芳香環之一二價有機基團。
本發明人研究發現,藉由使用包含一特定重複單元之聚醯胺酸、一特定雜環胺化合物以及丙烯酸甲酯基化合物之混合物,實現本發明中感光樹脂組成物之固化溫度可降至200℃或以下,以提供製程安全性、操作便利性與絕佳的發展性,並且提供樹脂具有彎曲性與感光性,由於改良樹脂的流性,此樹脂可填充不規則的圖案。
此雜環胺化合物可包含:吡啶(pyridine)、三唑(triazole)、咪唑(imidazole)、喹啉(quinoline)、以及三吖嗪(triazine),且雜環胺化合物係未經取代或由至少一官能基取代,此官能基係選自以下所組成之群組:一C1-C10的烷基(alkyl group)、一羥基(hydroxyl group)、以及一肟-衍生基團(oxime-derivative group)。當感光樹脂組成物使用雜環胺化合物時,其可加速固化製程並且使其於200℃或以下之溫度進行。較佳為,此雜環胺化合物可為未經取代或由下述官能基取代之雜環芳香胺化合物,如:吡啶(pyridine)、三唑(triazole)、咪唑(imidazole)、喹啉(quinoline)、以及三吖嗪(triazine)。
雜環胺化合物可與具有硫基(mercapto group)之化合物區隔,具有硫基取代的化合物應於相對高之溫度固化,且乾膜中的高分子樹脂會因為硫基的性質而提高其黏性。傳統領域中使用的硫基取代化合物,無法對聚醯胺酸的聚醯亞胺化(polyimidization)有大幅的影響,因此無法降低固化所需之溫度。相反地,上述之雜環胺化合物會加速聚醯胺酸的聚醯亞胺化,因而可簡化感光樹脂組成物的固化反應。

於化學式30中,X2
係如同化學式1所示。
特定的雙胺化合物之舉例,可為至少兩種選自以下所組成之群組:對苯二胺(p-phenylenediamine(p-PDA))、間苯二胺(m-phenylenediamine(m-PDA)、4-4’-氧基雙苯胺(4-4’-oxydianiline(4-4’-ODA))、3-4’-氧基雙苯胺(3-4’-oxydianiline(3-4’-ODA))、2,2-雙-(4-[4-胺苯氧基]苯基)丙烷(2,2-bis-(4-[4-aminophenoxy]-phenyl)propane(BAPP))、1,3-雙-(4-胺苯氧基)-苯(1,3-bis-(4-aminophenoxy)benzene(TPE-R))、1,4-雙-(4-胺苯氧基)苯(1,4-bis-(4-aminophenoxy)benzene(TPE-Q))、2,2-雙-(4-[3-胺苯氧基]苯基)碸(2,2-bis-(4-[3-aminophenoxy]phenyl)sulfone(m-BAPS))、及其相似化合物,但此例並非侷限於此。

舉例而言,此酸酐化合物包含至少一種化合物,其係選自以下所組成之群組:均苯四甲酸二酐(pyromelitic dianhydride)、3,3'-4,4'-聯苯四甲酸二酐(3,3'-4,4'-biphenyltetracarboxylic dianhydride)、3,3',4,4'-二苯基酮四甲酸二酐(3,3',4,4'-benzophenone tetracarboxylic dianhydride)、4,4'-氧基二酞酸酐(4,4'-oxydiphthalic anhydride)、4,4'-(4,4'-異丙基聯苯氧基)二酞酸酐(4,4'-(4,4'-isopropylbiphenoxy) biphthalic anhydride))、2,2'-雙-(3,4-二羧酸苯基)六氟丙烷二酐(2,2'-bis-(3,4-dicarboxylphenyl) hexafluoropropane di-anhydride)、乙二醇雙-(脫水-偏苯三酸酯)(ethylene glycol bis-(anhydro-trimellitate(TMEG))、及其相似化合物,但並非侷限於此。
聚醯胺酸之製備可由此領域中習知之有機合成方法製得。舉例來說,聚醯胺酸之製備可接續於溶劑中溶解一種或以上如化學式30之雙胺化合物,並加入一種或以上如化學式31或化學式32之二酸酐使其反應。較佳為,此雙胺化合物與二酸酐化合物係於0至5℃之溫度範圍開始反應,並且通常使其持續反應24小時,又或者於10至40℃之溫度範圍下直到反應完全為止。於此,較佳為將雙胺化合物與二酸酐化合物以莫耳比1: 0.9至1: 1.1相互混合,假如雙胺化合物與二酸酐化合物之莫耳比低於1: 0.9時,由於其分子量非常低,可能會使製造具有絕佳機械性質的聚醯亞胺(polyimide)變得困難。相反地,假如雙胺化合物與二酸酐化合物之莫耳比高於1: 1.1時,由於其黏度很高,可能會使所需之塗佈與操作之製程變得困難。
於製備聚醯胺酸所使用之溶劑,可為至少一種選自以下所組成之群組:N-甲基-2-吡咯烷酮(N-methyl-2-pyrrolidone(NMP))、N,N-二甲基乙醯胺(N,N-dimethyl acetamide(DMAc))、四氫呋喃(tetrahydrofuran(THF))、N,N-二甲基甲醯胺(N,N-dimethylformamide(DMF))、二甲基亞碸(dimethyl sulfoxide(DMSO))、環己烷(cyclohexane)、乙腈(acetonitrile)、及其混合物,但並非侷限於此。
聚醯胺酸之數量平均分子量(Mn)較佳為介於2000至300,000之範圍,更佳為8000至20,000。假如聚醯胺酸之數量平均分子量(Mn)低於2000,由於製成的聚醯胺酸組成物之分子量與黏性變低,可能會使製成的聚醯亞胺樹脂之物理性質變弱;此外,假如聚醯胺酸之數量平均分子量(Mn)高於300,000,由於聚醯胺酸漆中過高的黏性,會使得聚醯胺酸難以進行處理。
一種聚醯亞胺(polyimide)係包含如化學式2所示之重複單元,此聚醯亞胺可由包含一重複單元(如化學式1所示)之之聚醯胺酸製得。於聚醯胺酸進行醯亞胺化之例子中,化學醯亞胺化係將聚醯胺酸與醋酸酐(acetic acid anhydride)及嘧啶(pyrimidine)加入,之後加熱到50至100℃;熱醯亞胺化係將聚醯胺酸溶液塗佈於一基板上,之後將其置於100至250℃之烘箱內或一熱板上。
於化學式2中,X1
及X2
係如化學1所定義之。

此肟(oxime)或醛雩(aldoxime)衍生群組係分別相關於衍生自肟或醛雩之官能基,其醛雩衍生群組可包含一官能基,如化學式33所示:
於化學式33中,R1
可為氫、一C1至C10之烷基、或一C7至C15之酚烷基。
以聚醯胺酸作為100重量份時,可包含0.5至30重量份之雜環胺化合物,較佳為5至15重量份之雜環胺化合物。假如雜環胺化合物之含量低於1重量份時,可能會使得無法達到預定之固化程度;假如雜環胺化合物之含量超過30重量份時,會導致固化後薄膜的強度減弱。
感光樹脂組成物可包含丙烯酸甲酯基化合物,其丙烯酸甲酯基化合物之碳原子間係包含一種或以上之雙鍵。此丙烯酸甲酯基化合物與聚醯胺酸具有高度相容性,並且使其準備於紫外光曝曬後形成一負片(negative pattern)。
於此,「丙烯酸甲酯((metha)acrylate)」之用詞係意指丙烯酸甲酯((metha)acrylate)與丙烯酸(acrylate)之化合物。
以聚醯胺酸作為100重量份時,可使用5至200重量份之丙烯酸甲酯基化合物。假如包含丙烯酸甲酯基化合物之含量低於5重量份時,會使得其發展性變低;假如包含丙烯酸甲酯基化合物之含量超過200重量份時,可能會破壞其機械性質(如耐熱性與彈性)。
舉例而言,丙烯酸甲酯基化合物係為2-羥基甲基丙烯酸乙酯(2-hydroxyethyl(metha)acrylate)、甲基丙烯酸苄酯(benzyl(metha)acrylate)、苯氧基聚乙烯丙烯酸甲酯(phenoxypolyethylene(metha)acrylate)、甲氧基聚甲基丙烯酸丙二酯(methoxylpolypropyleneglycol(metha)acrylate)、2-羥基甲基丙烯酸丙酯(2-hydroxypropyl(metha)acrylate)、甲基丙烯醯氧基酞氫酸乙酯((metha)acryloyloxyethyl-hydrogenphthalate)、二(甲基丙烯酸)-(1,6-己二)酯(1,6-hexandioldi(metha)acrylate)、二(甲基丙烯酸)-(乙二)酯(ethandioldi(metha)acrylate)、亞甲基雙-丙烯酸甲酯(methylenebis-(metha)acrylate)、二(甲基丙烯酸)-新戊二酯(neopentylglycoldi(metha)acrylate)、2-羥基二(甲基丙烯酸)-(丙二)酯(2-hydroxypropandioldi(metha)acrylate)、二(甲基丙烯酸)-(異丙二)酯(isopropyldioldi(metha)acrylate)、二(甲基丙烯酸)-異丙二酯(isopropyleneglycoldi(metha)acrylate)、2-羥基甲基丙烯酸乙酯(2-hydroxyethylmethacrylate(HEMA))、酚基丙烯酸縮水甘油酯(phenylglycidylester acrylate(Kayarad R-128H))、環氧基丙烯酸-(1,6-己二)酯(1,6-hexanediol epoxy acrylate(Kayarad R-167))、Ebecyl 9695(以二甘醇乙醚醋酸(carbitol acetate)稀釋環氧丙烯酸酯寡聚物(epoxy acrylate oligomer))、或甲基丙烯酸縮水甘油酯(glycidyl(metha)acrylate),但並非侷限於此。此丙烯酸甲酯基化合物可獨立使用,或結合上述兩種以上之化合物一起使用。
此感光樹脂組成物係包含光起始劑,其光起始劑為一苯乙酮基化合物(acetophenone-based compound),例如:2-羥基-2-甲基-1-苯基-1-丙酮(2-hydroxy-2-methyl-1-phenyl propane-1-on)、1-(4-異丙基苯基)-2-羥基-2-甲基-1-丙酮(1-(4-isopropylphenyl)-2-hydroxy-2-methylpropane-1-on)、4-(2-羥基乙氧基)-苯基-(2-羥基-2-丙基)酮(4-(2-hydroxyethoxy)-phenyl-(2-hydroxy-2-propyl)ketone)、1-羥基環己烷基苯基酮(1-hydroxycyclohexyl phenylketone)、安息香甲醚(benzoin methyl ether)、安息香乙醚(benzoin ethyl ether)、安息香異丁醚(benzoin isobutyl ether)、安息香丁醚(benzoin butyl ether)、2,2-二甲氧基-2-苯基苯乙酮(2,2-dimethoxy-2-phenylacetophenone)、2-甲基-(4-甲硫基)苯基-2-嗎啉基-1-丙酮(2-methy1-(4-methylthio)phenyl-2-morpholino-1-propane-1-on)、2-苯基-2二甲基胺-1-(4-嗎啉基苯基)-1-丁酮(2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butane-1-on)、2-甲基-1-[4-(嗎啉基)苯基]-2-嗎啉基-1-丙酮(2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropane-1-on)、及其相似化合物;一雙咪唑基化合物(biimidazole-based compound),例如:2,2-雙-(2-氯苯基)-4,4’,5,5’-四苯基雙咪唑(2,2-bis-(2-chlorophenyl)-4,4',5,5'-tetraphenyl biimidazole)、2,2-雙-(鄰-氯苯基)-4,4’,5,5’-四(3,4,5-三甲氧基苯基)1,2’-雙咪唑((2,2'-bis-(o-chlorophenyl)-4,4',5,5'-tetrakis(3,4,5-trimethoxyphenyl)-1,2'-biimidazole)、2,2’-雙-(2,3-二氯苯基)-4,4',5,5'-四苯基-2,2’-雙-(鄰-氯苯基)-4,4’,5,5’-四苯基-1,2’-雙咪唑(2,2'-bis-(2,3-dichloro phenyl)-4,4',5,5'-tetraphenyl 2,2'-bis-(o-chlorophenyl)-4,4',5,5'-tetraphenyl-1,2'-biimidazole)、及其相似化合物;一三吖嗪基化合物(triazine-based compound),例如:3-{4-[2,4-雙-(三氯甲基)-s-三吖嗪-6-基]苯硫基}丙酸(3-{4-[2,4-bis-(trichloromethyl)-s-triazine-6-yl]phenylthio}propionic acid)、1,1,1,3,3,3-六氟異丙基-3-{4-[2,4-bis-(三氯甲基)-s-三吖嗪-6-基]苯硫基}丙酸(1,1,1,3,3,3-hexafluoro isopropyl-3-{4-[2,4-bis-(trichloromethyl)-s-triazine-6-yl]phenylthio}propionate)、乙基-2-{4-[2,4-雙-(三氯甲基)-s-三吖嗪-6-基]苯硫基}醋酸酯(ethyl-2-{4-[2,4-bis-(trichloro methyl)-s-triazine-6-yl]phenylthio}acetate)、2-環氧乙基ethyl-2-{4-[2,4-雙-(三氯甲基)-s-三吖嗪-6-基]苯硫基}醋酸酯(2-epoxyethyl-2-{4-[2,4-bis-(trichloromethyl)-s-tri-azine-6-yl]phenylthio}acetate)、環己烷基-2-{4-[2,4-雙-(三氯甲基)-s-三吖嗪-6-基]苯硫基}醋酸酯(cyclohexyl-2-{4-[2,4-bis-(trichloromethyl)-s-triazine-6-yl]phenylthi-o}acetate)、芐基-2-{4-[2,4-雙-(三氯甲基)-s-三吖嗪-6-基]苯硫基}醋酸酯(benzyl-2-{4-[2,4-bis-(trichloromethyl)-s-triazine-6-yl]phenylthi-o}acetate)、3-{氯-4-[2,4-雙-(三氯甲基-s-三吖嗪-6-基)苯硫基]丙酸}(3-{chloro-4-[2,4-bis-(trichloro methyl-s-triazine-6-yl)phenylthio-]propionic acid})、3-{4-[2,4-雙-(三氯甲基-s-三吖嗪-6-基)苯硫基]丙醯胺}(3-{4-[2,4-bis-(trichloromethyl-s-triazine-6-yl)phenylthio]propionamide})、2,4-雙-(三氯甲基)-6-對-甲氧基苯乙烯基styryl-s-三吖嗪(2,4-bis-(trichloromethyl)-6-p-methoxy styryl-s-triazine)、2,4-雙-(三氯甲基)-6-(1-對-二甲基胺苯基)-1,3-丁二烯基-s-三-吖嗪(2,4-bis-(trichloromethyl)-6-(1-p-dimethylaminophenyl)-1,3-butadienyl-s-tri-azine)、2-三氯甲基1-4-胺-6-對-甲氧基苯乙烯基-s-三吖嗪(2-trichloromethyl-4-amino-6-p-methoxystyryl-s-triazine)、及其相似化合物;以及一肟基化合物(oxime-based compound),例如日本的Chiba有限公司(Chiba,Co.,Ltd.)製造的CGI-242與CGI-124。然而,光起始劑不可侷限於上述之例子中。
以感光樹脂組成物中聚醯胺酸作為100重量份時,可使用0.3至10重量份之光起始劑。假如包含光起始劑之含量低於0.3重量份時,會降低碳原子間包含一個或以上雙鍵的丙烯酸甲酯化合物參與光固化反應;假如包含光起始劑之含量超過50重量份時,自由基將不參與固化反應,可能會降低感光樹脂製成的膜之物理性質。

實驗例1:膜變色
此乾膜之變色將使用裸眼評估。
實驗例2:聚醯亞胺之固化程度
使用鑽石衰減全反射式傅立葉紅外光譜儀(ATR FT-IR)探討聚醯亞胺之聚醯亞胺化速率,並且將聚醯胺酸之減少速率與標準固化條件之聚醯胺酸樣本相比較,以得到一數值。
實驗例3:顯影性質
將製得之乾膜在銅箔上以真空層積,並於350 mJ/cm2-
曝光,並且使用35℃之1wt%的碳酸鈉水溶液噴灑顯影,而製得的乾膜是否可進行顯影係使用L/S=50μm/50μm之高度檢查。

由實施例與比較例中獲得之乾膜的介電常數,係使用HP 4194A IMPEDENCE/GAIN-PHASE分析儀以ASTM D150方法進行測量。
如表1所示,由實施例獲得之乾膜固化程度皆為100%。然而,由比較例獲得之乾膜固化程度為95%或更低,由此證實於180℃下不易進行固化反應。此外,熱固化後的實施例之乾膜並不會變色,而比較例3的乾膜會變成咖啡色,並且在比較例5中顯示其乾膜的顯影性質並不好。
此外,由實施例中獲得的乾膜具有絕佳的黏性,因此難以將其分離。另一方面,由比較例中獲得的乾膜由於其固化程度較低,使其黏性較小。
另外,由實施例中獲得的乾膜由於其絕佳的焊接耐熱性,使其飄浮於288±5℃的焊接鍋持續1分鐘後都不會變形。然而,由比較例中獲得之乾膜,由於分離的現象導致其焊接耐熱性低。
本發明之較佳實施例以如上詳盡描述,但並不表示本發明之範圍僅侷限於此,本發明可由熟知此領域之技術者,可依本發明申請專利範圍中涵蓋之範圍內的基本觀念進行各種修改或改良。
