Latest Patents

Among Liu's latest patented inventions in the area of lateral MOSFET technology are two notable methods. The first patent describes a process that involves forming a first isolation region in a substrate, where the top surface of this region is lower than that of the substrate. This method includes depositing a gate electrode layer and patterning it to create first and second gate electrode regions, the latter vertically aligned with the first isolation region and adjacent to the first gate electrode region.

The second patent outlines a different method for forming a lateral MOSFET. In this approach, the first isolation region's top surface is level with the substrate's top surface initially. Subsequently, an upper portion of this isolation region is removed to create a recess. A gate dielectric layer is then deposited, followed by a gate electrode layer, which is patterned to form a gate electrode region. The first part of this region aligns with the first isolation region, while a second part is formed over the substrate, ensuring that the top surface of the first portion is lower than that of the second portion.
