Abstract: A method for forming a semiconductor device including a GaN FET, an overvoltage clamping component, and a voltage dropping component. The GaN FET is formed by forming a low-defect layer comprising gallium nitride, a barrier layer comprising AlxGa1?xN, a gate, and source and drain contacts. The overvoltage clamping component is coupled to a drain node of the GaN FET. The overvoltage clamping component conducts insignificant current when a voltage at the drain node is less than a safe voltage limit and conducts significant current when the voltage rises above the safe voltage limit. The voltage dropping component is coupled to the overvoltage clamping component and to a terminal for a bias potential. The voltage dropping component provides a voltage drop which increases as current from the overvoltage clamping component increases. The GaN FET turns on when the voltage drop reaches a threshold value.

Abstract: A semiconductor device includes a medium voltage MOSFET having a vertical drain drift region between RESURF trenches containing field plates which are electrically coupled to a source electrode of the MOSFET. A split gate with a central opening is disposed above the drain drift region between the RESURF trenches. A two-level LDD region is disposed below the central opening in the split gate. A contact metal stack makes contact with a source region at lateral sides of the triple contact structure, and with a body contact region and the field plates in the RESURF trenches at a bottom surface of the triple contact structure. A perimeter RESURF trench surrounds the MOSFET. A field plate in the perimeter RESURF trench is electrically coupled to the source electrode of the MOSFET. An integrated snubber may be formed in trenches formed concurrently with the RESURF trenches.

Abstract: Electric Vehicle Service Equipment (EVSE) and Electric Vehicle (EV) are disclosed n. In an example embodiment, a modem is coupled to the pilot wire that couples the EVSE and the EV. The modem transmits both pulse width modulation (PWM) command signals and power line communication (PLC) signals to a remote device via the pilot wire. The modem interleaves the PWM and PLC signals on the pilot wire so that latency requirements for the PWM signals are maintained. The modem supports parallel protocol stacks in which PLC signals are processed in a first path and PWM signals are processed in a second path that bypasses the first path and provides the PWM signals directly to a MAC layer. The modem may create a modified frame for the PLC signals to maintain the latency requirements.

Abstract: User equipment (UE)-initiated accesses within a cellular network are optimized to account for cell size and to reduce signaling overhead. A fixed set of preamble parameter configurations for use across a complete range of cell sizes within the cellular network is established and stored within each UE. A UE located in a given cell receives a configuration number transmitted from a nodeB serving the cell, the configuration number being indicative of a size of the cell. The UE selects a preamble parameter configuration from the fixed set of preamble parameter configurations in response to the received configuration number and then transmits a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.

Leadframe pad has a portion recessed as pocket with a depth and an outline suitable for attaching the first chip with one terminal in the pocket and the opposite terminal co-planar with the un-recessed pad surface. The interposer comprises metal patterned in traces separated by gaps; the traces include metal of a first height and metal of a second height smaller than the first height, and insulating material filling the gaps and the height differences; one interposer side attached to the leadframe pad with the first chip, the opposite interposer side attached to the terminals of the second chip.
Abstract: A first depth map is generated in response to a stereoscopic image from a camera. The first depth map includes first pixels having valid depths and second pixels having invalid depths. In response to the first depth map, a second depth map is generated for replacing at least some of the second pixels with respective third pixels having valid depths. For generating the second depth map, a particular one of the third pixels is generated for replacing a particular one of the second pixels. For generating the particular third pixel, respective weight(s) is/are assigned to a selected one or more of the first pixels in response to value similarity and spatial proximity between the selected first pixel(s) and the particular second pixel. The particular third pixel is computed in response to the selected first pixel(s) and the weight(s).

Abstract: A system comprising a processor and a compression module coupled to the processor. The compression module is adapted to perform motion estimation on video data using an algorithm, the motion estimation performed at a rate. If the processor determines a difference between the rate and a target rate, the processor adjusts a precision level of the algorithm such that the difference is decreased.
Abstract: A semiconductor device is formed by forming a deep trench in a substrate and a dielectric liner on sidewalls of the deep trench. A first undoped polysilicon layer is formed on the semiconductor device, extending into the deep trench on the dielectric liner, but not filling the deep trench. Dopants are implanted into the first polysilicon layer. A second layer of polysilicon is formed on the first layer of polysilicon. A thermal drive anneal activates and diffuses the dopants. In one version, the dielectric liner is removed at the bottom of the deep trench before the first polysilicon layer is formed, so that the polysilicon in the deep trench provides a contact to the substrate. In another version, the polysilicon in the deep trench is isolated from the substrate by the dielectric liner.
