YI-HANN 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: 9982338
    Abstract: A system includes an implantation chamber; a warming chamber, wherein the warming chamber is outside of the implantation chamber and has a sidewall shared with the implantation chamber; a first robotic arm configured to move a first wafer from the implantation chamber into the warming chamber; and a second robotic arm configured to move a second wafer into the implantation chamber.
    Type: Grant
    Filed: May 17, 2017
    Date of Patent: May 29, 2018
    Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.

  • Patent number: 9663854
    Abstract: A high throughput system for warming a wafer to a desired temperature after undergoing a low-temperature implantation process includes an implantation chamber, a wafer warming chamber configured to uniformly warm a single wafer, and a plurality of robotic arms to transfer wafers throughout the system. At each stage in the fabrication process, the robotic arms simultaneously work with multiple wafers and, therefore, the system provides a high throughput process. Also, the warming chamber may be a vacuum environment, thus eliminating the mist-condensation problem that results in wafer spotting.

  • Patent number: 9378990
    Abstract: Among other things, a system and method for adjusting the intensity of a laser beam applied to a semiconductor device are provided for herein. A sensor is configured to measure the intensity of a laser beam reflected from the semiconductor device. Based upon the reflection intensity, an intensity of the laser beam that is applied to the semiconductor device is adjusted, such as to alter an annealing operation performed on the semiconductor device, for example.

  • Publication number: 20140273533
    Abstract: A semiconductor annealing method and system uses a vacuum pump to produce a vacuum environment in the annealing chamber to thereby remove undesired gas element influences. A control system obtains pressure and temperature measurements from the annealing chamber to control operation of the heating elements and vacuum pump to thereby maintain process integrity.
