Latest Patents

One of Lei Zhong's latest patents is focused on ion implantation to form trench-bottom oxide of MOSFET. This patent discloses methods for forming MOSFETs, which include providing a device structure with multiple trenches and forming a mask over the structure. The method involves removing the mask from within the trenches while retaining it on the top surface, followed by implanting the device structure to create a treated layer at the bottom of the trenches. Additionally, the method includes forming a gate oxide layer along the sidewalls and bottom of the trenches, ensuring that the oxide thickness at the bottom is greater than that along the sidewalls.

Another notable patent is a method for increasing photoresist etch selectivity to enable high energy hot implant in SiC devices. This process involves providing a hardmask layer on a substrate, followed by a photoresist layer that defines a pattern. The method includes performing a room temperature ion implantation process to enhance the exposed portion of the hardmask layer, followed by an etching process to reveal the underlying substrate. Finally, a high energy, hot ion implantation process is conducted on the exposed substrate.
