Definitions
- the present invention relates to a liquid epoxy resin composition for semiconductor encapsulation, a semiconductor device sealed with a cured product of the resin composition, and a method for manufacturing a resin-encapsulated semiconductor device.
- sealing molding can be performed without any major problem even at present, but if the diameter is 12 inches or more, the shrinkage stress of epoxy resin or the like after sealing is large, so that the semiconductor element is made of metal or the like. Problems such as peeling from the substrate occur, and mass production cannot be achieved.
- thermosetting resin when entirely sealed on the silicon interposer, a large warp is generated due to the difference in thermal expansion coefficient between silicon and the thermosetting resin. If the warpage is large, it cannot be applied to the subsequent polishing process or individualization process, which is a major technical problem.

Description
スマートフォン、タブレットなど携帯情報、通信端末は大容量の情報を高速で処理できるよう、TSV(スルー-シリコン-ビア)技術を用いて半導体素子を多層接続し、8インチ乃至12インチのシリコンインターポーザーにフリップチップ接続した後、熱硬化樹脂により、多層接続された半導体素子が複数個搭載されたインターポーザーごと封止する。半導体素子上の不要な硬化樹脂を研磨した後、個片化し、薄型で小型、多機能かつ高速処理可能な半導体装置を得ることができる。
