Description
また、前記基板が基板コア材の上面に無機材料を貼ったもので、前記無機材料をパターニングすることによってダイボンド用パッドの主部と導電パターンが同一材料で形成されているので、基板コア材の上面に無機材料を貼った基板、たとえばプリント基板の導電パターンを利用してダイボンド用パッドを作製することができ、電子部品のコストを抑えることができる。
図4は本発明の実施形態1による電子部品の構造を示す断面図、図5は図4のX部拡大図である。また、図6は基板の上面図である。ここに示す電子部品51は、基板52の上面に半導体素子53を実装し、基板52と導電性キャップ54からなるパッケージ(ファラデーケージ)内に半導体素子53を納めたものである。
図12は本発明の実施形態1による電子部品の変形例を示す断面図であって、図5に対応する箇所の断面を表している。この変形例では、ダイボンド用パッド55の上にソルダーレジスト67を設けていない。すなわち、導電パターン部61aの上面全体をAuメッキ等の無機材料61bで覆い、この上にダイボンド樹脂68によって半導体素子53の下面を接合固定したものである。このような構造であっても、ダイボンド時にダイボンド樹脂68がダイボンド用パッド55の内周側にも外周側にも流れ出る恐れがない。また、ダイボンド樹脂68が流れ出る恐れがないので、半導体素子53の下面とダイボンド用パッド55との間のダイボンド樹脂68の厚みのばらつきを小さくでき、電子部品の特性を安定させることができる。
