Abstract:
A semiconductor device comprising:a multilayer laminate that includes a thermally stable, flexible polymer film, the laminate having a top surface and a bottom surface; a semiconductor die having a top surface and a bottom surface, the die's bottom surface contacting the laminate's top surface, and having substantially vertical sides oriented substantially perpendicular to the die's top and bottom surfaces; a molding compound contacting both the laminate's top surface and the sides of the die, but not the die's top or bottom surfaces, the molding compound having a first surface that contacts the laminate and a second surface and having sides oriented substantially perpendicular to the molding compound's first and second surfaces, a first portion of those sides contacting the die and a second portion of those sides not contacting the die; and a heat dissipation member that comprises: a heat conductor having a thickness approximately equal to the thickness of the second portion of the sides of the molding compound, comprising a material selected from the group consisting of silicon, molybdenum, and aluminum silicon carbide, and contacting substantially all of the die's top surface, and a heat spreader, having a surface area exceeding the molding compound's surface area, that contacts the heat conductor and the second surface of the molding compound and that comprises a material selected from the group consisting of copper and aluminum.
