Title: Innovations of Won Sic Woo

Introduction

Won Sic Woo is a prominent inventor based in Guri-si, South Korea. He has made significant contributions to the field of semiconductor technology, holding a total of nine patents. His work primarily focuses on methods for fabricating advanced memory devices.

Latest Patents

Among his latest patents is a method for forming a NAND typed memory device. This innovative approach includes defining a select transistor region and a memory cell region in a semiconductor substrate. It involves forming a tunnel insulating layer, a floating gate conductive layer, and a dielectric layer over the substrate. The process also includes etching the dielectric layer to create an opening that exposes the floating gate conductive layer. Additionally, a low resistance layer is formed in the opening, followed by the creation of a control gate conductive layer. The final steps involve etching various layers to form gate stacks of memory cells and source/drain select transistors.

Another notable patent is the method of forming conductive lines of a semiconductor memory device. This method comprises forming a first polysilicon layer over an underlying layer and patterning it to create first polysilicon patterns. The process continues with filling the spaces between these patterns with an insulating layer and etching the top portion to form recess regions. Spacers are then formed on the sidewalls of these regions, followed by filling the recesses with a second polysilicon layer to create second polysilicon patterns. The final step involves a metal silicidation process to convert these patterns into metal silicide patterns.
