Latest Patents
One of his latest patents is titled "Method and apparatus for verifying stitching accuracy of stitched chips on a wafer." This invention discloses a method for verifying the stitching accuracy of a stitched chip on a wafer. Initially, a set of test structures are inserted within a reticle layout. An exposure program is executed to control photolithography equipment, specifically a stepper, to perform multiple exposures of the reticle on a wafer, generating a stitched chip. Electrical measurements are then performed on the test structures at actual stitch boundaries to evaluate the stitching accuracy of the stitched chip.
Another significant patent is the "Method for fabricating resistors within semiconductor integrated circuit devices." This patent describes a process for fabricating resistors within a semiconductor integrated circuit device. The method begins with depositing a passivation layer on a semiconductor substrate that has multiple transistors formed thereon. Subsequently, contact windows are created, filled with metal, and planarized to form bottom contacts. A resistive film is then deposited, followed by the formation of a second passivation layer and top contacts to connect the resistive film.
