Latest Patents
One of Tsuei's latest patents is for an LDMOS transistor structure designed to improve hot carrier reliability. This innovative structure reduces hot carrier effects by increasing the size of the drain region relative to the source region. By doing so, the concentration of electrons entering the drain region is minimized, which leads to fewer impact ionizations and enhances the overall performance of the LDMOS.
Another significant patent involves a method of using trenching techniques to create a transistor with a floating gate. This method allows for the development of electrically programmable and erasable memory cells. It utilizes shallow trench isolation techniques to form a floating gate with sharply defined tip characteristics. The process includes forming a first insulating layer over a substrate, followed by the creation of a trench filled with oxide to define the edges of the floating gate during etching.
