  • Patent number: 12140974
    Abstract: The present disclosure relates to a method for stochastic inspections on power grid lines based on unmanned aerial vehicle-assisted edge computing. According to the method, a stochastic distributed inspection unmanned aerial vehicle is adopted to acquire video images on a target power grid area, which can reduce funds and time costs of inspections. With assistance of superior unmanned aerial vehicle, a goal is to minimize energy consumption of an unmanned aerial vehicle system and extend operation time of the unmanned aerial vehicles under same payload conditions, while processing video image data collected from the inspection unmanned aerial vehicles. The near-far effect generated by communications between mobile unmanned aerial vehicles is eliminated by introducing a NOMA, and position coordinates, system resource allocations and task offload decision schemes are solved by using a method of combining a DDPG algorithm in a Deep reinforcement learning with a genetic algorithm.

  • Patent number: 10566441
    Abstract: Methods of forming integrated circuits are provided herein. In an embodiment, a method of forming an integrated circuit includes providing a semiconductor substrate. The semiconductor substrate includes a plurality of gate structures that have sidewalls spacers disposed adjacent to the gate structures. A gap is defined between sidewall spacers of adjacent gate structures. The method proceeds with decreasing an aspect ratio between a width of the gap at an opening thereto and a depth of the gap, wherein an aspect ratio between a width of the gap at a base of the sidewall spacers and the depth of the gap remains substantially unchanged after decreasing the aspect ratio between the width of the gap at the opening thereto.

  • Patent number: 10410854
    Abstract: The present disclosure generally relates to methods for cleaning the backside of a wafer. A wet cleaning method may be used by stripping off the uppermost spacer layers on the backside of the wafer using a cleaning solution. In one embodiment, hydrogen fluoride (HF) solution may be employed to remove the nitride/oxide spacer layer. In another embodiment, a dry cleaning method may be employed to etch the wafer at the bevel region. Residues are completely removed from the wafer backside. This method improves the yield and storage life of the semiconductor wafers.
