Latest Patents

One of his latest patents is titled "CMOS sensor with shallow and deep regions." This invention describes a CMOS sensor that includes a substrate, a gate electrode, a source/drain region, and a sensor region. The source/drain region is formed on one side of the gate electrode, while the sensor region is located on the opposite side. The impurity in the source/drain region is arsenic, and it also features a lightly doped drain region. The sensor region consists of a first and a second doped region, both of which have a dentoid profile, with phosphorus as the impurity.

Another significant patent is "Method of forming a CMOS sensor." This method involves creating shallow first doped regions in a substrate adjacent to a gate electrode. One of these regions is designated as a source/drain area, while another serves as a sensor area. A spacer is formed on the sidewall of the gate electrode, and a second doped region is implanted within the sensor area, which is deeper than the first doped region. This innovative approach enhances the performance of the sensor region.
