ABSTRACT:
A semiconductor device having a substrate support (22) and a method of forming the semiconductor device. A substrate (11) has conductive traces (12) and a bonding pad (13) on a bottom surface and conductive traces (14) and a semiconductor chip attach pad (17) on a top surface. The substrate support (22) has an aperture (23) and is coupled to the substrate (11). A semiconductor chip (31) is coupled to the semiconductor chip attach pad (17). The semiconductor chip (31) is covered by an encapsulating material (38) or a cap (41, 51) which provide protection for the semiconductor chip (31).
