Description
また、第一電極と第二電極との間隔を狭いものとして、第一電極と第二電極とで形成される静電容量を大きなものとなり、絶縁板の変動が小さなものであっても、外部の圧力を感度良く検出することができる。
1b・・・・・・・・・・搭載部
2・・・・・・・・・・・絶縁板
3・・・・・・・・・・・半導体素子
5、5a、5b・・・・・配線導体
7・・・・・・・・・・・第一電極
9・・・・・・・・・・・第二電極
Claims (2)
- 一方の主面に半導体素子が搭載される搭載部を有する絶縁基体と、該絶縁基体の表面および内部に配設され、前記半導体素子の各電極が電気的に接続される複数の配線導体と、前記絶縁基体の他方の主面との間に密閉空間を形成するように可撓な状態で前記絶縁基体に接合された絶縁板と、前記密閉空間内の前記絶縁基体の前記他方の主面に被着され、前記配線導体の一つに電気的に接続された静電容量形成用の第一電極と、前記絶縁板の内側の主面に前記第一電極と対向するように被着され、前記配線導体の他の一つに電気的に接続された静電容量形成用の第二電極と、を具備している圧力検出装置用パッケージであって、前記絶縁板は、前記絶縁基体との接合部の内側に位置する部位の両主面がそれぞれ前記絶縁板の中央部の厚みが前記絶縁板の外周部から中央部に向かうにともなって漸次厚くなるような凸形の曲面であって、平面視において外側主面側の凸形の曲面とされている部位の外周が、内側主面側の凸形の曲面とされている部位の外周よりも大きくなるように形成されていることを特徴とする圧力検出装置用パッケージ。
- 請求項1記載の圧力検出装置用パッケージと、前記搭載部に搭載されるとともに前記電極が前記配線導体に電気的に接続された前記半導体素子と、前記絶縁基体の前記一方の主面の前記搭載部の周囲に前記半導体素子を覆うように取着された蓋体または前記絶縁基体の前記一方の主面に前記半導体素子を覆うように被着された封止樹脂とを具備していることを特徴とする圧力検出装置。
