Title: The Innovations of Jih-Chang Lien
Introduction
Jih-Chang Lien is a prominent inventor based in San Jose, California, known for his significant contributions to the field of nonvolatile memory technology. With a total of four patents to his name, Lien has made strides in enhancing memory device efficiency and density.
Latest Patents
Among his latest patents is a groundbreaking invention titled "Nonvolatile memory cell with vertical gate overlap and zero birds beaks." This innovative memory device, such as a flash EEPROM, features zero birds' beaks and vertically overlapping gates, which facilitate high cell density in the EEPROM's core. During the fabrication process, a layer of field oxide is formed over the core, and the active regions are exposed by etching through this layer to create vertically walled cavities around the active regions. The tunnel oxide, floating gate, interpoly dielectric, and control gate are formed within each cavity, allowing the floating gate to overlap the control gate along the vertical walls. This design maintains capacitive coupling between the gates while reducing the horizontal dimensions of the cell. The absence of birds' beaks further enhances cell density in the core.
