Abstract
Semiconductor devices and methods for making semiconductor devices. The present invention allows a flip chip assembly to be used with an optical semiconductor device. The optical semiconductor flip chip is positioned over a hole in a PCB such that the imaging area of the optical semiconductor flip chip faces the hole. The hole allows the imaging area to be unobstructed by the PCB. Underfill material can be prevented from going into the hole by erecting a barrier on top of the PCB that surrounds the hole.
