  • Publication number: 20230137108
    Abstract: Techniques described herein include performing a first anneal operation on a first portion of the interconnect, filling the remaining portion of the interconnect, and then performing a second anneal operation on the interconnect. The two-step anneal techniques described herein enable the removal of defects in an interconnect structure, particularly for high aspect ratio interconnect structures. Accordingly, the two-step anneal techniques described herein may be used to fabricate defect free or near defect free interconnect structures in a semiconductor device. This reduces contact resistance for the interconnect structures, reduces premature device failure for the semiconductor device, increases manufacturing yield, and increases tolerance of the interconnect structures to subsequent processing operations, among other examples.

  • Patent number: 11630362
    Abstract: A one-way glass with switching modes includes an absorbing layer located on a weak light side, a reflecting layer located on an intense light side, and a converting layer stacked between the absorbing layer and the reflecting layer. The absorbing layer absorbs first polarized light and allows second polarized light to pass through. The reflecting layer reflects the first polarized light and allows the second polarized light to pass through. Unpolarized light incident from the weak light side or from the intense light side is respectively converted into the polarized light. During the process of gradually adjusting the converting layer from a twisted state to a vertical state, rotated angles of polarization directions of the first polarized light and the second polarized light gradually decrease.

  • Publication number: 20230092969
    Abstract: An embodiment of the present invention is directed toward machine learning to produce results encompassing a new output. A machine learning model is trained to determine a candidate output from among a plurality of candidate outputs. First embeddings associated with the plurality of candidate outputs are generated from a first set of training data by an intermediate layer of the trained machine learning model. Second embeddings associated with a new candidate output are generated from a second set of training data by the intermediate layer of the trained machine learning model. A third embedding is determined for input data by the intermediate layer of the trained machine learning model. A resulting candidate output for the input data is predicted from a group of the plurality of candidate outputs and the new candidate output based on distances for the third embedding to the first and second embeddings.

  • Publication number: 20230087097
    Abstract: A booster engine enhances the quality of a frame sequence. The booster engine receives, from a first stage circuit, the frame sequence with quality degradation in at least a frame. The the quality degradation includes at least one of uneven resolution and uneven frame per second (FPS). The booster engine queries an information repository for reference information on the frame, using a query input based on at least a region of the frame to obtain a query output. The booster engine then applies a neural network to the query input and the query output to generate an optimized frame, and sends an enhanced frame sequence including the optimized frame to a second stage circuit.
