Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 半導体素子配線のファインピッチ化や高密度 実装化、薄型化に充分に対応でき、しかも半導体素子の 封止に用いる絶縁性樹脂とフィルムキャリアとの間の密 着性に優れ、信頼性の高い半導体装置を提供する。 【構成】 導電回路5は、絶縁体層6の両面6a,6b に露出しないように埋設されており、導電回路5の両面 5a,5bから導通路7,8が、導電回路5の面方向に ずれて対をなして形成されている。各導通路7,8はバ ンプ9,10にそれぞれ接続しており、導電回路5と各 バンプ9,10とは、各導通路7,8を介して導通して いる。フィルムキャリア2の一方の導通路7の片端部に 形成されたバンプ9は、半導体素子3の電極12に接触 して、電気的に接続され、フィルムキャリア2は半導体 素子3を搭載している。この半導体素子3を被覆するよ うに、絶縁体層6の片面6aに接して、絶縁性樹脂層4 が形成されている。 (57) [Abstract] [Purpose] Adhesion between the insulating resin used to seal the semiconductor element and the film carrier, which can sufficiently support fine pitch, high-density mounting and thinning of semiconductor element wiring. An excellent semiconductor device with high reliability is provided. [Structure] The conductive circuit 5 includes both surfaces 6a and 6b of an insulator layer 6. The conductive paths 7 and 8 are formed so as not to be exposed to the outside, and the conductive paths 7 and 8 are formed from the both surfaces 5a and 5b of the conductive circuit 5 so as to be displaced in the surface direction of the conductive circuit 5. The conductive paths 7 and 8 are connected to the bumps 9 and 10, respectively, and the conductive circuit 5 and the bumps 9 and 10 are conductive via the conductive paths 7 and 8. The bump 9 formed on one end of the one conduction path 7 of the film carrier 2 is in contact with the electrode 12 of the semiconductor element 3 and electrically connected thereto, and the film carrier 2 has the semiconductor element 3 mounted thereon. The insulating resin layer 4 is in contact with the one surface 6a of the insulator layer 6 so as to cover the semiconductor element 3. Are formed.
