Patents by Inventor Miao-Pei Chen

Miao-Pei Chen 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: 11971365
    Abstract: A wafer processing system and a rework method thereof are provided. An image capture device captures an image of a wafer to generate a captured image. A control device detects a defect pattern in the captured image, calculates a target removal thickness according to distribution of contrast values of the defect pattern, and controls a processing device to perform processing on the wafer according to the target removal thickness.
    Type: Grant

  • Patent number: 11852465
    Abstract: The disclosure provides a wafer inspection method and wafer inspection apparatus. The method includes: receive scanning information of at least one wafer, wherein the scanning information includes a plurality of haze values; the scanning information is divided into a plurality of information blocks according to the unit block, and the feature value of each of the plurality of information blocks is calculated according to the plurality of haze values included in each of the plurality of information blocks; and converting the feature value into a color value according to the haze upper threshold and the haze lower threshold, generating the color value corresponding to the at least one wafer according to the converted color value according to the feature value, whereby the color graph displays the texture content of the at least one wafer.

  • Publication number: 20220307991
    Abstract: A wafer surface defect inspection method and a wafer surface defect inspection apparatus are provided. The method includes the following steps. Scanning information of a wafer is received, and the scanning information includes multiple scanning parameters. At least one reference point of the scanning information is determined, and path information is generated according to the at least one reference point and a reference value. Multiple first scanning parameters corresponding to the path information in the scanning parameters are obtained according to the path information to generate a curve chart. According to the curve chart, it is determined whether the wafer has a defect, and a defect type of the defect is determined.
