The invention is a semiconductor avalanche photodetector including an essentially undoped multiplication layer; a thin, undoped light absorbing layer; and a doped waveguide layer which is separate from the light absorbing layer and is capable of coupling incident light into the light absorbing layer.

High speed semiconductor photodetector

A bond pad having reduced capacitance is disclosed which is useful in fabricating integrated circuit and communications devices. The bond pad is disposed within a select bond pad area and comprises a ribbon of conductive material within the select pad area and a two-phased region of air and conductive material. Also, at least one interconnect area is disposed within the bond pad area. The ribbon is coupled to the two-phased region, and the interconnect is coupled to the ribbon and to the device. Inclusion of air within the bond pad structure reduces the capacitance of the device, while the surface area of the bonding pad is maintained to at least substantially retain the adhesive properties of the pad.
