Shih-Yu LIAO 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: 11355544
    Abstract: The present disclosure describes a method for the formation of mirror micro-structures on radiation-sensing regions of image sensor devices. The method includes forming an opening within a front side surface of a substrate; forming a conformal implant layer on bottom and sidewall surfaces of the opening; growing a first epitaxial layer on the bottom and the sidewall surfaces of the opening; depositing a second epitaxial layer on the first epitaxial layer to fill the opening, where the second epitaxial layer forms a radiation-sensing region. The method further includes depositing a stack on exposed surfaces of the second epitaxial layer, where the stack includes alternating pairs of a high-refractive index material layer and a low-refractive index material layer.
    Type: Grant

  • Patent number: 11131541
    Abstract: The present disclosure is directed to a method and system for monitoring a distance between a shutter and a reference point in a processing module. For example, the method includes moving a shutter relative to a substrate support in a wafer processing module and determining a distance between the shutter and a wall of the wafer processing module with a measurement device. In response to the distance being greater than a value, the method further includes transferring a substrate to the substrate support, and in response to the distance being equal to or less than the value, the method includes resetting the shutter.
