Description
図1は本発明の実施の形態1に係る半導体装置を示す裏面図である。図2〜図4は本発明の実施の形態1に係る半導体装置を示す側面図である。図5は図1のI−IIに沿った断面図である。図6は図5の制御用半導体素子の固着部分を拡大した上面図である。
図12は、本発明の実施の形態2に係る半導体装置の製造方法を示す断面図である。保護部材14は、キャビティ19の天井に対して斜め向きに設けられている。これによりトランスファーモールド時に上金型17を閉じた際に保護部材14が弾性域の変形で上金型17に追従して、保護部材14にかかる応力を保護部材14が一部吸収するため、上金型17の磨耗を減らすことができる。
図13は、本発明の実施の形態3に係る半導体装置の製造方法を示す断面図である。保護部材14は、制御用リード5との固着部分から先端に向かって細くなる。これにより、保護部材14が更に応力を緩和するため、上金型17の磨耗を更に減らすことができる。
図14は、本発明の実施の形態4に係る半導体装置の製造方法を示す断面図である。保護部材14に切欠き22が設けられている。これにより、保護部材14が更に応力を緩和するため、上金型17の磨耗を更に減らすことができる。
図15は、本発明の実施の形態5に係る半導体装置の製造方法を示す断面図である。保護部材14はスプリング状である。これにより、保護部材14が更に応力を緩和するため、上金型17の磨耗を更に減らすことができる。
