Claim Text:
1. A high-reliability semiconductor package structure, comprising: a lower heat sink made of a thermally conductive material and having an upper surface and a bottom surface, wherein an annular recess is formed on the upper surface to enclose an adhesion region of the upper surface; a die having a first surface fixedly coupled to the adhesion region and having a second surface opposing the first surface; an upper heat sink made of an electrically and thermally conductive material and having a connection portion and a first bending unit, the connection portion being adhered tightly to the second surface of the die, wherein an area of the connection portion is not less than an area of the second surface of the die; a lead frame made of an electrically conductive material and having a second bending unit and a bent pin, the second bending unit being adhered tightly to the first bending unit, wherein a portion of the bent pin and the bottom surface are coplanar; and a package body for enclosing the die, the upper heat sink, a portion of the lead frame, and a portion of the lower heat sink, wherein the bent pin and the bottom surface are exposed from the package body.
