Description
図1乃至図10は、本発明の実施の形態の半導体デバイスおよび半導体デバイスの製造方法を示している。
図1に示すように、半導体デバイス10は、第1基体11と第2基体12と導体フィルム13とを有している。
半導体デバイス10は、柱状の導体から成る複数の接続柱24の両端部24aを、それぞれ第1電極21cおよび第2電極22cに接合することにより、第1電極21cと第2電極22cとを電気的に接続することができる。半導体デバイス10は、第1基体11と第2基体12とを面同士で接合しないため、第1基体11および第2基体12の互いの対向面の平坦性を、面同士で接合する場合ほど精密に制御する必要がない。また、第1基体11および第2基体12の互いの対向面の間に粒子等が入り込んだとしても、その粒子等から外れた位置の接続柱24により、第1電極21cと第2電極22cとの電気的な接続が確保されるため、面同士で接合する場合ほど粒子等の侵入を厳密に制御する必要もない。このように、半導体デバイス10は、制御に関するコストを抑制することができる。また、面同士で接合する場合と比較して、電気的な接続を容易に確保することができ、歩留まりを高めることができる。
