Abstract:
Lateral and vertical microstructure enhanced photodetectors and avalanche photodetectors are monolithically integrated with CMOS/BiCMOS ASICs and can also be integrated with laser devices using fluidic assembly techniques. Photodetectors can be configured in a vertical PIN arrangement or lateral metal-semiconductor-metal arrangement where electrodes are in an inter-digitated pattern. Microstructures, such as holes and protrusions, can improve quantum efficiency in silicon, germanium and III-V materials and can also reduce avalanche voltages for avalanche photodiodes. Applications include optical communications within and between datacenters, telecommunications, LIDAR, and free space data communication.

Claim (Index 46):
A method of manufacturing a microstructure-enhanced photodetector comprising:\n providing one or more laterally extending, non-doped or low-doped I-layers of semiconductor material, plural electrodes electrically coupled with said one or more I-layers and configured to produce an electrical field therein, and a microstructure comprising a laterally extending multiplicity of deliberately formed holes in said photodetector; said providing step further comprising:\n forming said one or more I-layers as continuous layers except for any penetration thereof by said holes; \n configuring said photodetector to respond to illumination with spatially continuous light at each of one or more regions each encompassing a multiplicity of said holes, in a direction transverse to said one or more I-layers, by producing an electrical output that depends on said illumination; \n configuring said holes to enhance a desirable electrical response of said photodetector to said light in one or more selected wavelength ranges compared to an electrical response of an otherwise same photodetector without said holes; and \n monolithically integrating said photoconductor on or in a single chip with one or more active electronic circuits and electrically connecting said photodetector and said active electronic circuits for transfer of said electrical output to said circuits for processing thereby.
