  • Patent number: 12243948
    Abstract: Techniques for enhancing the absorption of photons in semiconductors with the use of microstructures are described. The microstructures, such as pillars and/or holes, effectively increase the effective absorption length resulting in a greater absorption of the photons. Using microstructures for absorption enhancement for silicon photodiodes and silicon avalanche photodiodes can result in bandwidths in excess of 10 Gb/s at photons with wavelengths of 850 nm, and with quantum efficiencies of approximately 90% or more.

  • Patent number: 12094903
    Abstract: Microstructure enhanced photodector arrangements uses a CMOS image sensor (CIS) wafer of crystalline Si and a CMOS Logic Processor (CLP) wafer stacked on each other for electrical interaction. The wafers can be fabricated separately and stacked or can be regions of the same monolithic chip. The image can be a time-of-flight image. Bayer arrays are enhanced with microstructure holes. Avalanche photodiodes, single photon avalanche photodiodes and phototransistors can be laterally and/or vertically doped. Photodetectors/photosensors can have slanted sidewalls for improved optical confinement and reduced crosstalk.

  • Publication number: 20230354620
    Abstract: Resistive RAM (RRAM) devices having increased reliability and related manufacturing methods are described in combination with stacked technology with CMOS ASIC wafters. Greater reliability of RRAM cells over time can be achieved by avoiding direct contact of metal electrodes with the device switching layer. Stacking technology can be used to address incompatibility of ReRAM processing and CMOS ASICs processing.

  • Patent number: 11791432
    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.
