Description
図1は、本実施の形態に係る電力用半導体装置の構造を示す縦断面図であり、又、図2は、図1中の線I―Iに関する縦断面構造の一部を拡大して示す図である。
本変形例は、実施の形態1の半導体装置を改良するものであり、その特徴点は、1)導電性パイプ7は、その内表面7IS上に全面的に形成された絶縁膜10を更に備えており、しかも、2)モールド樹脂4は導電性パイプ7の全体を被覆すると共に、3)モールド樹脂4は、導電性パイプ7の一端部に繋がった冷媒液導入口6ENと、導電性パイプ7の他端部に繋がった冷媒液出口6EXとを備える点にある。以下、この点を、図面を基に具体的に記載する。
図4は、本実施の形態に係る電力用半導体装置の構造を示す縦断面図である。本装置が実施の形態1に係る図1の装置と構造上相違する特徴点の一つは、A)導電性パイプ7の使用に代えて、冷却用冷媒液8(絶縁性の物でも良いし、あるいは、安価な水の様な導電性の物でも良い)の通路を成す内空間を形成する内表面9ISと、その一部が平面領域9OSFRを成す外表面9OSとを備える絶縁性パイプ9を用いている点にある。尚、平面部9OSFRは、中央部9CPのみならず、両端部9E1,9E2の一方あるいは双方にも形成されていても良い。この構造のため、B)第1外部接続端子6Aは、絶縁性パイプ9の平面9OSFR上に接合されたパッド部6APPを備えるインナーリード部6AILと、インナーリード部6AILに繋がったアウターリード部6AOLとを備える。そして、C)電力用半導体素子1は、溶接ろう材(接着層)2を介して、第1外部接続端子6Aのパッド部6APP上に固着されている。この様に、電力用半導体素子1は、パッド部6APPを介在して、冷媒経路を成すパイプ9によって間接的に冷却される。その他の構成要素3,5は図1の対応する要素と同一である。そして、D)トランスファーモールド成形によって、電力用半導体素子1の全面と、溶接ろう材2の全面と、第1及び第2外部接続端子6,5の各インナーリード部6AIL,5ILの全体と、ワイヤ3の全体と、絶縁性パイプ9の外表面9OSの全体とは、モールド樹脂4によって完全に被覆されている。
図4の絶縁性パイプ9として、その断面形状が当初より矩形型のパイプを用いても良い。この様なパイプの採用により、パイプの外表面の一部に平面形状を形成するための作業(プレス作業等)が不要となり、本半導体装置の製造が容易となる。
以上、本発明の実施の形態を詳細に開示し記述したが、以上の記述は本発明の適用可能な局面を例示したものであって、本発明はこれに限定されるものではない。即ち、記述した局面に対する様々な修正や変形例を、この発明の範囲から逸脱することの無い範囲内で考えることが可能である。
