Introduction

Kou-Cheng Wu is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on enhancing the performance and efficiency of semiconductor devices.

Latest Patents

Wu's latest patents include a semiconductor structure with a dielectric-sealed doped region. This innovation allows for a substantial reduction in leakage current by replacing the conventional junction between source/drain regions and the substrate material with a seal dielectric. The process involves forming trenches in the substrate, lining them with a seal dielectric, and filling the trenches with semiconductor material. The trenches are preferably overfilled, and a chemical mechanical polishing (CMP) process is used to planarize the overfill material. Additionally, an epitaxial layer can be grown atop the trenches after planarization if desired.

Another significant patent is related to a memory device. This invention features a floating gate positioned over a substrate, with a tunneling dielectric layer interposed between the floating gate and the substrate. An inter poly dielectric layer is placed over the floating gate and the substrate. The design includes a word line extending over the floating gate in a row direction and a bit line in the substrate extending in a column direction, partially overlapping with both the floating gate and the word line.
