Abstract
A method for making an improved semiconductor device package is provided. A semiconductor die (16) is attached to a supportive substrate (10, 12). A protective lid (20) is attached to the supportive substrate (10, 12), over the semiconductor die (16). The protective lid (20) is partially encapsulated with molding compound (28). The protective lid (20) prevents the molding compound (30) from contacting the semiconductor die (16), and associated wirebonded wires (18). A portion (30) of the protective lid (20) remains exposed. Thus, a molded package compatible with current product designs and assembly processes is provided, yet disadvantages caused by molding compound contacting the die (16) and wires (18) are avoided. Furthermore, the exposed protective lid (30) provides superior heat dissipation for the package.
