Abstract
【解決手段】 絶縁層15およびベース板1の側面には平面ほぼ半円形状の溝26が設けられている。溝26内には、グラウンド層2と上層配線19の一部とを接続するための上下導通部27が設けられている。したがって、例えば、絶縁層15およびベース板1に設けられたスルーホール内に上下導通部を設ける場合と比較して、上下導通部27の外側には絶縁層15およびベース板1が存在しないため、その分、小型化を図ることができる。なお、ベース板1の下面に通常の下層配線を設ける場合も同様である。
【選択図】 図1
Description
図1はこの発明の第1実施形態としての半導体装置の断面図を示す。この半導体装置は、ガラス布基材エポキシ樹脂等からなる平面方形状のベース板1を備えている。ベース板1の上面全体には銅箔からなるべたパターンのグラウンド層2が設けられている。グラウンド層2の上面全体には導電性接着層3が設けられている。
図20はこの発明の第2実施形態としての半導体装置の断面図を示す。この半導体装置において、図1に示す場合と異なる点は、下層下地金属層23を含む下層配線24をパターニングして通常の配線とし、下層配線24の接続パッド部に対応する部分における下層オーバーコート膜25に開口部51を設け、下層オーバーコート膜25下にコンデンサや抵抗等からなるチップ部品52を下層配線24の接続パッド部に半田等からなる導電材53を介して接続させて搭載した点である。この場合、下層配線24は通常の配線であるので、下層配線24の少なくとも一部と上層配線19の少なくとも一部とを接続するための上下導通部27の本数はそれに応じた本数である。
図21はこの発明の第3実施形態としての半導体装置の断面図を示す。この半導体装置において、図20に示す場合と異なる点は、グラウンド層2および導電性接着層3を有せず、半導体構成体4のシリコン基板5の下面をダイボンド材からなる接着層54を介してベース板1の上面に接着した点である。
例えば、図20では、上層絶縁膜16上に設ける上層配線を1層とし、下層絶縁膜37下に設ける下層配線を1層としているが、これに限らず、上層絶縁膜16上に設ける上層配線を2層以上とし、また、下層絶縁膜37下に設ける下層配線を2層以上としてもよい。また、下層オーバーコート膜25下に搭載される電子部品は、チップ部品53に限らず、例えば、ベアチップ、CSP等であってもよい。
