ABSTRACT:
A semiconductor device (10) coupled to ball grid array substrate (11) and encapsulated by an optically transmissive material (29, 31). The ball grid array substrate (11) has conductive interconnects (14) and a semiconductor receiving area (17) on a top surface and solder pads (13) on a bottom surface. An optoelectronic component (24) is mounted on the semiconductor receiving area (17) and encapsulated with the optically transmissive material (29, 31). Solder balls (18) are formed on the solder pads (13).
