  • Publication number: 20230306300
    Abstract: An electronic device manufacturing system configured to obtain sensor data associated with a deposition process performed in a process chamber to deposit a film stack on a surface of a substrate. The film stack can include a known film pattern and an unknown film pattern. The manufacturing system is further configured to input the sensor data into a first trained machine-learning model to obtain a first output value of the first trained machine-learning model. The first output value can be associated with the known film pattern. The manufacturing system is further configured to input the first output value into a second trained machine-learning model to obtain a second output value of the second trained machine-learning model. The second output value can be indicative of metrology data of the known film pattern.

  • Publication number: 20210357758
    Abstract: A method for deep neural network compression is provided. The method includes: using at least one weight of a deep neural network (DNN), setting a value of a P parameter, and combining every P weights in groups, and perform branch pruning and retraining, so that only one of each group has a non-zero weight, and the remaining weights are 0, wherein the remaining weights are evenly divided into branches to adjust a compression rate of the DNN and to adjust a reduction rate of the DNN.

  • Patent number: 10241540
    Abstract: A portable electronic device includes a host module having a housing with an accommodation space, a display module and a lift structure. The display module is pivotally connected to the housing by a shaft. The lift structure includes a bottom cover covering the accommodation space, a swing member and a follower member. The bottom cover includes an abutment portion including an abutment surface and located on an end surface of the bottom cover adjacent to the accommodation space. The swing member is in the accommodation space and connected to the shaft. The swing member moves with the display module. The follower member connects to the swing member and contacts the abutment surface. The follower member moves in a first direction according to swinging of the swing member, therefore the follower member abuts against the abutment surface and the bottom cover moves in a second direction to lift up the housing.
