US10418415B2 Interconnect capping process for integration of MRAM devices and the resulting structures
Approaches for an interconnect cladding process for integrating magnetic random access memory (MRAM) devices, and the resulting structures, are described. In an example, a memory structure includes an interconnect disposed in a trench of a dielectric layer above a substrate, the interconnect including a diffusion barrier layer disposed at a bottom of and along sidewalls of the trench to an uppermost surface of the dielectric layer, a conductive fill layer disposed on the diffusion barrier layer and recessed below the uppermost surface of the dielectric layer and an uppermost surface of the diffusion barrier layer, and a conductive capping layer disposed on the conductive fill layer and between sidewall portions of the diffusion barrier layer. A memory element is disposed on the conductive capping layer of the interconnect.
US10418410B2 Optoelectronic modules operable to collect spectral data and distance data
Optoelectronic modules operable to collect distance data and spectral data include demodulation pixels operable to collect spectral data and distance data via a time-of flight approach. The demodulation pixels include regions with varying charge-carrier mobilities. Multi-wavelength electromagnetic radiation incident on the demodulation pixels are separated into different portions wherein the respective portions are used to determine the composition of the incident multi-wavelength electromagnetic radiation. Accordingly, the optoelectronic module is used, for example, to collect colour images and 3D images, and/or ambient light levels and distance data. The demodulation pixels comprise contact nodes that generate potential regions that vary in magnitude with the lateral dimension of the semiconductor substrate. The potential regions conduct the photo-generated charges from the photo-sensitive detection region to a charge-collection region. The photo-generated charges are conducted to the charge-collection region with respective drift velocities that vary in magnitude with the thickness of the semiconductor substrate.
US10418409B2 Image sensor based on avalanche photodiodes
Disclosed herein is an apparatus comprising: an array of avalanche photodiodes (APDs), each of the APDs comprising an absorption region and an amplification region; wherein the absorption region is configured to generate charge carriers from a photon absorbed by the absorption region; wherein the amplification region comprises a junction with an electric field in the junction; wherein the electric field is at a value sufficient to cause an avalanche of charge carriers entering the amplification region, but not sufficient to make the avalanche self-sustaining; wherein the junctions of the APDs are discrete.
US10418405B2 Sensor chip and electronic apparatus
A sensor chip includes: a pixel array unit that has a rectangular-shaped area in which a plurality of sensor elements are arranged in an array pattern; and a global control circuit, in which driving elements simultaneously driving the sensor elements are arranged in one direction, and each of the driving elements is connected to a control line disposed for each one column of the sensor elements, that is arranged to have a longitudinal direction to be along a long side of the pixel array unit. For example, the present technology can be applied to ToF sensor.
