HEAT-DISSIPATING MEMBER AND MANUFACTURING METHOD THEREOF
To improve manufacturing stability (such as the yield) in manufacturing, e.g., a power module by connecting a component to one surface of a curved heat-dissipating member.SOLUTION: There is provided a substantially rectangular plate-shaped heat-dissipating member provided with a metal-silicon carbide composite comprising Al or Mg. One of the main surfaces of the heat-dissipating member curves in a convex manner toward the exterior of the heat-dissipating member, and the other main surface curves in a convex manner toward the interior of the heat-dissipating member. In a curved line C formed by the other main surface when the heat-dissipating member is viewed in a cross-sectional view at a cross-section that is roughly perpendicular to the heat-dissipating member and passes through both central points of the two short edges of the other main surface, (2h/L)/(H/L) is at least 1.1, where: a straight line passing through two end points Pand Pof the curved line C is l, the point on the curved line C where the distance from lis the greatest is P, an intersection of land a perpendicular line coming down from Pto lis P, the central point of the line segment PPis P, an intersection of the curved line C and a straight line that passes through Pand is perpendicular to lis P, the length of the line segment PPis L, the length of the line segment PPis H, and the length of the line segment PPis h.SELECTED DRAWING: Figure 1
【課題】湾曲した放熱部材の片面に部品を接続しパワーモジュール等を製造する際の製造安定性（歩留まり等）を改善する。【解決手段】Ａｌ又はＭｇを含む金属−炭化珪素複合体を備えた実質的に矩形で板状の放熱部材。放熱部材の一方の主面は放熱部材の外側方向に、他方の主面は放熱部材の内側方向に凸に湾曲している。この放熱部材を、放熱部材に略垂直で、かつ、他方の主面の２つの短辺の中点の両方を通る断面で断面視したときの、他方の主面が成す曲線Ｃにおいて、曲線Ｃの両端点Ｐ１およびＰ２を通る直線をｌ１、曲線Ｃ上でのｌ１との距離が最大となる点をＰｍａｘ、Ｐｍａｘからｌ１に下ろした垂線とｌ１との交点をＰ３、線分Ｐ１Ｐ３の中点をＰ４、Ｐ４を通りｌ１に垂直である直線と曲線Ｃとの交点をＰｍｉｄ、線分Ｐ１Ｐ３の長さをＬ、線分Ｐ３Ｐｍａｘの長さをＨ、線分Ｐ４Ｐｍｉｄの長さをｈとしたとき、（２ｈ／Ｌ）／（Ｈ／Ｌ）は１．１以上である。【選択図】図１
