Description
本発明は、電気的に安定な相互接続を与えるために超小型電子デバイス又は半導体パッケージにおいて導電性材料として使用されるのに適した組成物に関する。
超小型電子デバイス及び半導体パッケージの作製及び組立において、導電性組成物が様々な目的に使用されている。例えば、導電性接着材は、集積回路チップを基板に接着するために(ダイ取り付け用接着材)又は回路アセンブリを印刷配線基板に接着するために(表面実装導電性接着材)使用される。
本発明は低応力、等方性、導電性のフィルム又はペースト接着材に関し、その接着材はa)1以上の官能性アクリルコポリマー又はターポリマー;b)エポキシ樹脂;及びc)導電性フィラーを含む。接着促進剤、硬化剤、導電性向上剤等の追加の成分も利用できる。本発明の導電性フィルム接着材は従来のフレキシブル導電性フィルム接着材よりも高い接着強度を与え、現存する高接着強度導電性フィルムよりも被接着部品間の低い応力を与える。
本発明の導電性接着材は、a)1以上の官能性アクリルコポリマー又はターポリマー;b)エポキシ樹脂;及びc)導電性フィラーを含む。好ましい態様において、1以上の接着促進剤、硬化剤及び導電率添加剤も含むことができる。ここで、官能性アクリルコポリマーに関して言及される場合、官能性アクリルコポリマーはターポリマーを含んでもよいと理解される。
本発明の官能性アクリルコポリマーは表1中の成分で配合処方された。
2 RSL-1462 DGEGA epoxy(Resolution Performance Productsから商業的に入手可能)
3 Dicyanex 1400B(Air Productsから)
4 導電性促進剤及び銀充填剤は専売材料(proprietary materials)である。
表1の配合物Aの性能は商業的に入手できる高接着強度エポキシ樹脂及び低応力エポキシ樹脂の性能と共に試験した。試験された高接着強度エポキシ樹脂(比較例A)はCF3350(Emerson & Cumingから商業的に入手可能)であり、試験された低応力エポキシ樹脂(比較例B)は845OWL(AI Technologiesから商業的に入手可能)であった。これら試験の結果を表2に示す。
