Latest Patents
One of his latest patents is titled "Method for evaluating non-uniform stress." This method evaluates thin film non-uniform stress using high order wafer warpage. The process includes measuring the net wafer warpage across a wafer area due to thin film deposition, fitting a two-dimensional low-order polynomial to the wafer warpage measurements, and subtracting the low-order polynomial from the net wafer warpage across the wafer area. Another significant patent is "Alignment mark for MRAM device and method." This patent provides structures and formation methods of a semiconductor structure that includes an insulating layer covering a device region and an alignment mark region of a semiconductor substrate. A conductive feature is formed in the insulating layer and corresponds to the device region. The alignment mark structure includes a first conductive layer, a second conductive layer covering the first conductive layer, and a first magnetic tunnel junction (MTJ) stack layer covering the second conductive layer. The first conductive layer and the conductive feature are made of the same material.
