Title: Inventor Ru-Yin Tong: Pioneering Innovations in Magnetic Tunneling Junctions

Introduction

Ru-Yin Tong, based in San Jose, California, is a notable inventor with a robust portfolio of three patents. His innovative contributions primarily focus on enhancing magnetic tunneling junction (MTJ) technology, which has significant implications for memory storage solutions such as magnetic random-access memory (MRAM).

Latest Patents

One of Ru-Yin Tong's latest patents introduces a sophisticated underlayer design for high-performance magnetic tunneling junction MRAM. This MRAM structure features a bottom electrode with an amorphous TaN capping layer. This design enables the consistent and dense growth of antiferromagnetic (AFM), pinned, tunnel barrier, and free layers within the MTJ. Unlike traditional Ta capping layers, TaN offers oxidation resistance and boasts a high resistivity, effectively preventing shunting of the sense current due to redeposition on the sidewalls of the tunnel barrier layer. Additionally, the α-TaN layer may function as a seed layer in the MTJ, with potential composite layers comprised of NiCr, NiFe, or NiFeCr on the α-TaN. The inclusion of an α-TaN capping or seed layer is also applicable in a TMR read head, and MTJs utilizing the α-TaN capping layer have shown impressive results, featuring a high MR ratio, higher voltage bias (Vb), and resistance area (RA) outcomes comparable to those derived from MTJs with an optimized Ta capping layer.
