Latest Patents

Liou's latest patents include a "Dummy structure for multiple gate dielectric interface and methods." This invention discloses dummy structures positioned between high voltage (HV) and low voltage (LV) regions of a substrate. The design features a HV gate dielectric over the HV region and a LV gate dielectric over the LV region, with a dummy structure placed on the sidewall of the HV gate dielectric. The thickness of the LV gate dielectric is intentionally less than that of the HV gate dielectric, optimizing the device's functionality.

Another significant patent is the "Semiconductor seal ring." This invention provides a semiconductor seal ring and outlines methods for its formation. The seal ring consists of multiple dielectric layers over a semiconductor substrate, with conductive layers arranged among these dielectric layers. An upper conductive layer is formed over the dielectric layers, and a passivation layer is added to protect it from conductive debris during the die saw process. This design helps prevent undesired short circuits, particularly in regions close to die saw cut lines.
