Latest Patents

One of his latest patents is an electrostatic discharge (ESD) protection structure. This invention provides an ESD protection structure compatible with bipolar-CMOS-DMOS (BCD) processes, which enhances protection performance and improves heat dissipation. The design utilizes the bipolar punch characteristics of the parasitic bipolar structure to bypass ESD current, significantly reducing trigger voltage and increasing ESD protection levels. Additionally, the ESD protection circuit improves heat dissipation by avoiding current crowding near the surface. Another significant patent is for a multi-finger transistor, which includes multiple parallel transistors. Each transistor features a gate dielectric layer, a gate, a source/drain region, and a drift region in the peripheral substrate of the source/drain region. The width of the drift region increases stepwise from the edge sections of the multi-finger transistor toward the central section.
