Description
まず、半導体装置の電気的特性の評価を行う半導体評価装置の構成について説明する。
本発明の実施の形態2では、図1の各コンタクトプローブ7に対応して、複数の開口部および導電層を形成することを特徴している。その他の構成は、実施の形態1(図4参照)と同様であるため、ここでは説明を省略する。
本発明の実施の形態3では、保護膜を複数の層を積層して形成することを特徴としている。その他の構成は、実施の形態1(図4参照)または実施の形態2(図6参照)と同様であるため、ここでは説明を省略する。
半導体装置では、コンタクトプローブが接触する中央部の素子領域だけでなく、外周部である終端領域の近傍(例えば、半導体装置の側面と導電層との間)においても部分放電が頻繁に発生することが知られている。そのため、終端領域の近傍における部分放電の発生を抑制することが望まれる。
