Abstract
Description
図1は、本発明の実施の形態1にかかる半導体装置である電力用半導体装置100の側面図である。図2は、本発明の実施の形態1にかかる電力用半導体装置100の電力用半導体モジュール110に第1放熱グリス31と第2放熱グリス32とが配置された状態を放熱面側から見た図である。図3は、本発明の実施の形態1にかかる電力用半導体装置100の電力用半導体モジュール110の断面図であり、図2におけるIII−III線に沿った断面図である。なお、図3においては、理解の容易のため2つの電力用半導体素子2を示しているが、実際には、より多くの電力用半導体素子2が実装される。
図7は、本発明の実施の形態2にかかる半導体装置である電力用半導体装置130の側面図である。図8は、本発明の実施の形態2にかかる電力用半導体装置130の電力用半導体モジュール140に第1放熱グリス31と第2放熱グリス32とが配置された状態を放熱面側から見た図である。本実施の形態2にかかる電力用半導体装置130は、第1放熱グリス31および第2放熱グリス32の配置パターンが実施の形態1にかかる電力用半導体装置100と異なる。図7および図8においては、実施の形態1にかかる電力用半導体装置100と同様の構成については、実施の形態1にかかる電力用半導体装置100と同じ符号を付している。
