摘要：An improved power miconductor device and manufacturing method are described wherein the external, thermally conducting, heat transfer face (68a) of the device (94) is electrically insulated by a glassy dielectric (68) which is intimately bonded
急救法directly to the conductive heat spreader (61) supporting the miconductor die (84). By forming the expod corners of the heat spreader (61) to be substantially smooth curved surfaces (61 d) having a predetermined minimum radius of curvature (61e) greater than the thickness (67) of the glassy dielectric (68), formation of a ridge of glass at the corners (80) and edges (61c) of the heat spreader is avoided. For ea of asmbly the piece parts (82) are initially substantially flat and parallel. A molding compound (90) of controlled shrinkage is ud to avoid distorting the substantially flat smooth insulated heat transfer face (68a) which remains expod in the encapsulated device (94).
