Abstract
【解決手段】複数の半導体チップ2を備え、各半導体チップ2の電極層に接続されるコレクタ電極端子3及びエミッタ電極端子7を半導体チップ2方向に押圧して設ける。半導体チップ2とエミッタ電極端子7との間に熱応力緩和部材5を介在させる。この熱応力緩和部材5とエミッタ電極端子7は、複数の接合部6でもって接合される。接合部6,6間に設けられる熱応力緩和部材5の長さは、接合部6,6間の距離よりも長くする。熱応力緩和部材5は、厚さ0.1mm以下の箔状に形成される。また、コレクタ電極端子3の半導体チップ2と対向する面に形成された嵌合溝3aにコンタクト電極4を嵌合し、コレクタ電極端子3とコンタクト電極4を一体形成する。
【選択図】図1
