Semiconductor device and manufacturing method thereof
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 機械的強度や耐湿性といった半導体装置とし ての信頼性が高く、しかも多層板表面全体に配線パター ンを形成して集積度を向上させることのできる半導体装 置及びその製造方法を提供する。 【解決手段】 2層板52の配線パッド41b,41b 上に導体バンプ60,60,…を形成し、バリアメタル 層61とAu層62を形成し、その上に半導体素子70 を実装する。更にその上に開口部31aを設けたプリプ レグ31と、もう一つの2層板54を位置合わせし、ヒ ートプレスする。得られた半導体装置1の表面には半導 体素子70の周囲に充填した絶縁性樹脂と2層板54と の境界面は現れない。 PROBLEM TO BE SOLVED: To provide a semiconductor device having high reliability as a semiconductor device, such as mechanical strength and moisture resistance, capable of improving a degree of integration by forming a wiring pattern on the entire surface of a multilayer board, and manufacturing thereof. Provide a method. SOLUTION: Wiring pads 41b of a two-layer board 52 Are formed thereon, a barrier metal layer 61 and an Au layer 62 are formed, and a semiconductor element 70 is formed thereon. Implement Further, the prepreg 31 having the opening 31a provided thereon and another two-layer plate 54 are aligned and heat-pressed. No boundary surface between the insulating resin filled around the semiconductor element 70 and the two-layer plate 54 appears on the surface of the obtained semiconductor device 1.
