Latest Patents

Among his latest patents is a groundbreaking invention related to NAND flash memory devices and methods of manufacturing the same. This patent discloses a NAND flash memory device where the source and drain select transistor gates are recessed lower than the active region of a semiconductor substrate. This design allows for a longer valid channel length of the source and drain select transistor gates compared to the memory cell gates. As a result, the electric field between the source region and the drain region of the select transistor is reduced, effectively preventing program disturbance in edge memory cells adjacent to the select transistors in non-selected cell strings.

Another notable patent involves a method of manufacturing a NAND flash memory device. In this invention, a semiconductor substrate is selectively or entirely recessed to a predetermined depth in the area where the source select line (SSL) and drain select line (DSL) will be formed. This innovation increases the channel length of the gate, thereby reducing disturbance and improving the reliability and yield of the devices.
