Title: Innovations of Ching-Song Yang

Introduction

Ching-Song Yang is a prominent inventor based in Chang-Hua Hsien, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of seven patents. His work focuses on non-volatile memory structures, which are crucial for modern electronic devices.

Latest Patents

One of his latest patents is a non-volatile semiconductor memory structure. This invention includes a method of manufacturing a non-volatile semiconductor memory cell structure. The method involves forming a shallow first-type well layer, a second-type well layer, and a deep first-type well layer over a substrate. Stack gates are formed over the shallow first-type well layer, followed by the formation of source and drain terminals. The source terminals penetrate through the shallow first-type well layer and connect with the second-type well layer, while the drain terminals are positioned close to the surface of the shallow first-type well layer. Both types of terminals contain second-type dopants.

Another notable patent is for a non-volatile semiconductor memory device that features divided bit lines. In this design, a main bit line is controlled by at least one bit line selection device, allowing it to transfer its potential to a selected sub bit line. This innovation ensures that memory cells in a selected sector operate effectively while preventing overloads caused by parasitic capacitance. The arrangement of memory cells and the bit line selection device in parallel within a P-well and an N-well, respectively, helps to avoid disturbances during programming or erasing the bit line.
