【発明の詳細な説明】 (技術分野) 本発明は混成集積回路に関し、とくにその回路保護材料

重要な問題となっている。
(発明の目的) 本発明の目的は上記の不都合を解決する構成を提供する
ことにある。
(発明の構成) 本発明の構成は、従来、一般的に用いられていたシリコ

、混成集積回路全体としての機械的強度が保たれるよう
密清することが必要である。また半導体チップ5はシリ

(発明の効果) 本発明のポリウレタン系樹脂によると樹脂材料の性質か

、搭載部品として使用される高集積度IC素子に対して
も十分な不純物対策がなされたものである。

コン系の樹脂が一般的であったが、信頼性品質の要求が
高まるにつれて湿度的、熱的な限界があることが判明し
た〇本発明によって、上記の欠陥に対して一応の対等が
行われるので、混成集積回路の利用範囲の拡大、信頼性
品質の向上が期待出来る。
