Abstract:
1. A method of making a semiconductor package device, comprising: attaching a semiconductor chip to a metallic structure using an insulative adhesive, wherein the chip includes a conductive pad, the metallic structure includes first and second opposing surfaces and a lead, the adhesive is disposed between the first surface and the chip, the lead includes a recessed portion, a non-recessed portion and opposing outer edges between the first and second surfaces that extend across the recessed and non-recessed portions, and the recessed portion is recessed relative to the non-recessed portion at the second surface; forming an encapsulant that contacts the chip, the first surface, the outer edges and the recessed portion, wherein the encapsulant covers the chip, the outer edges and the recessed portion, and the non-recessed portion extends outside the encapsulant; and forming a connection joint that electrically connects the lead and the pad.
