Patent ID: 7227267

Claim:
A semiconductor package using flip-chip mounting technique, comprising: a semiconductor device provided with a plurality of first pads extending from the semiconductor device; a substrate provided with a plurality of second pads extending from the substrate at positions in registry with the location of the first pads of the semiconductor device; and an anisotropic conductive material interposed between the plurality of first pads and the plurality of second pads to electrically connect the first pads to associated second pads, the anisotropic conductive material positioned at discrete locations around the semiconductor device, thereby providing unobstructed clearance at desired locations between the semiconductor device and the substrate; and wherein the semiconductor device comprises an optical modulating device and the substrate is transparent to light, so that light is transmitted through the transparent substrate and is incident on the optical modulating device, and is reflected from the optical modulating device to be output through the transparent substrate.
