Latest Patents

Hyang-ja Yang's latest patents include innovative designs that enhance the performance of semiconductor memory devices. One of her patents, titled "Electrostatic discharge protection circuit," describes a semiconductor memory device that conserves chip area by jointly connecting transistors adjacent to each other. This device features first and second electrostatic discharge protection MOSFET transistors, which have drains connected to adjacent pads, defining a first active area. A common source is arranged between the two transistor areas, creating a second active area shared by both transistors. The design allows for connection to a single power supply at the gates and sources, while also sharing common active ground lines.

Another significant patent is the "Electrostatic discharge structure of semiconductor device." This structure includes a semiconductor substrate doped with P-type impurities, an N-type well, and a P-type pocket well. It also features an N-type active guardline and a P-type active guardline, both doped to higher concentrations. The design ensures that even if a negative voltage due to electrostatic charge is temporarily applied to the drain region of the NMOS transistor, it prevents malfunctions in the internal circuitry of the P-type semiconductor substrate.
