Patents by Inventor Guo-Xin Hu

Guo-Xin Hu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11927887
    Abstract: An optical proximity correction (OPC) operation method and an OPC operation device are provided. The OPC operation method includes the following steps. A mask layout is obtained. If the mask layout contains at least one defect hotspot, at least one partial area pattern is extracted from the mask layout according to the at least defect hotspot. A machine learning model is used to analyze the local area pattern to obtain at least one OPC strategy. The OPC strategy is implemented to correct the mask layout.

  • Publication number: 20230358605
    Abstract: A matching method of light source parameters includes the following. First light source parameter data of a first exposure machine and second light source parameter data of a second exposure machine corresponding to the first light source parameter data are collected. Whether a second light intensity distribution included in the second light source parameter data meets a first light intensity distribution included in the first light source parameter data is determined. If the second light intensity distribution meets the first light intensity distribution, a simulated exposure process is performed by using the first light source parameter data and the second light source parameter data. Second simulated exposure data obtained by using the second light source parameter data is compared with first simulated exposure data obtained by using the first light source parameter data to determine whether the second simulated exposure data meets the first simulated exposure data.

  • Patent number: 8765495
    Abstract: A method of forming a pattern of doped region includes the following steps. At first, a device layout pattern including a gate layout pattern and a doped region layout pattern is provided to a computer system. Subsequently, the device layout pattern is split into a plurality of sub regions, and the sub regions have different pattern densities of the gate layout pattern. Then, at least an optical proximity correction (OPC) calculation is respectively performed on the doped region layout pattern in each of the sub regions to respectively form a corrected sub doped region layout pattern in each of the sub regions. Afterwards, the corrected sub doped region layout patterns are combined to form a corrected doped region layout pattern, and the corrected doped region layout pattern is outputted onto a mask through the computer system.
