Description
ダメージを防止することができる。このため、パワートランジスタが形成されているパワートランジスタ形成領域の真上にパッド25を形成しても、クリップ28で接続する際、ダメージをパワートランジスタに与えることはない。したがって、パワートランジスタ形成領域にパッド25を配置することができる。このため、パワートランジスタ形成領域の外部にパッド25を配置する場合に比べて、半導体チップ20のサイズを縮小化することができる。このように、本実施の形態によれば、パワートランジスタに接続するパッド25とリード27aとをクリップ28で接続する構成をとることにより、パワートランジスタのオン抵抗を低減することができるだけでなく、同時に半導体チップの縮小化も実現することができる。
