  • Publication number: 20240144430
    Abstract: A computing system performs artificial-intelligence (AI) super-resolution (SR). The computing system includes multiple processors, which further includes a graphics processing unit (GPU) and an AI processing unit (APU). The computing system also includes a memory to store AI models. When detecting an indication that the loading of the GPU exceeds a threshold, the processors reduce the resolution of a video output from the GPU in response to the indication. One of the AI models is selected based on graphics scenes in the video and the respective power consumption estimates of the AI models. The processors then perform AI SR operations on the video using the selected AI model to restore the resolution of the video for display.

  • Publication number: 20230411193
    Abstract: When there is an interruption in power to an area of an integrated circuit manufacturing facility, product may be stranded in a vehicle mounted to an automated material handling system. An automated rescue vehicle can be deployed to retrieve the stranded vehicle so that a payload carried by that vehicle can be recovered and processing can resume. The rescue vehicle can carry a battery payload. The battery payload provides backup power while the rescue operation is performed. With such an automated system, no human intervention is needed to recover product during a power outage. In addition to improving wafer throughput during the power outage, such a rescue operation may prevent quality degradation for time-critical sequences of processing operations.

  • Publication number: 20230066085
    Abstract: A photodetector including a substrate having a semiconductor material layer, such as a silicon-containing layer, and a germanium-based well embedded in the semiconductor material layer, where a gap is located between a lateral side surface of the germanium-based well and the surrounding semiconductor material layer. The gap between the lateral side surface of the germanium-based well and the surrounding semiconductor material layer may reduce the surface contact area between the germanium-containing material of the well and the surrounding semiconductor material, which may be a silicon-based material. The formation of the gap located between a lateral side surface of the germanium-based well and the surrounding semiconductor material layer may help minimize the formation of crystal defects, such as slips, in the germanium-based well, and thereby reduce the dark current and improve photodetector performance.
