Patents by Inventor Guangdian Chen

Guangdian 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: 11333614
    Abstract: An inspection system of semiconductor device includes a light source for producing a light beam, a lens module including at least one metalens, a receiver, and a processor. During an inspection process, the light beam emitted from the light source is focused on a target object by the metalens of the lens module and is reflected to form a reflected light by the target object. The receiver is used for receiving the reflected light. The processor is used for receiving an electric signal corresponding to the reflected light and generating an inspection result.
    Type: Grant

  • Patent number: 11112482
    Abstract: The present invention provides a method for calibrating verticality of a particle beam. The method includes: providing a baseplate having a first sensor and a second sensor; emitting the particle beam to the first sensor of the baseplate from an emitter, such that a first datum is collected when the first sensor receives the particle beam; emitting the particle beam to the second sensor of the baseplate from the emitter, such that a second datum is collected when the second sensor receives the particle beam; calculating a first calibrating datum based on the first datum and the second datum; and adjusting the baseplate or the emitter based on the first calibrating datum if the first calibrating datum is out of a first predetermined range.
