Abstract
【解決手段】プローブを用いたICテストを行った後のパッド部は第2のパッシベーション膜158で被覆されている。そのため、ICテストの後に施されるバリアメタルの除去工程において使用されるウェットエッチング用の薬液から、ICテストの実施によって部分的に薄くなったパッド部を保護することができる。したがって、パッド部を介した、ICチップ内への薬液の侵入を抑制することができる。また、半導体装置100においては、プローブを用いたICテストを行うパッド部と、金属バンプ電極162を形成するための開口部とが分離されている。そのため、ICテストによって生じたプローブ痕164の影響が金属バンプ電極162の形状に及ぶことを抑制することができる。
