Title: Innovations of Wei D Z Zou in Giant Magnetoresistive Devices

Introduction

Wei D Z Zou is a notable inventor based in Minnetonka, MN (US). He has made significant contributions to the field of magnetoresistive devices, holding two patents that showcase his innovative methods. His work primarily focuses on the fabrication of giant magnetoresistive (GMR) devices, which are essential in various technological applications.

Latest Patents

Wei D Z Zou's latest patents include methods for fabricating giant magnetoresistive (GMR) devices. In these methods, a plurality of magnetoresistive device layers is deposited on a first silicon nitride layer formed on a silicon oxide layer. An etch stop is created on the magnetoresistive device layers, followed by the formation of a second layer of silicon nitride on the etch stop. The magnetoresistive device layers are then patterned to define multiple magnetic bits with sidewalls. The second silicon nitride layer is patterned to create electrical contact portions on the etch stop in each magnetic bit. The sidewalls of the magnetic bits are covered with a photoresist layer. A reactive ion etch (RIE) process is employed to etch into the first silicon nitride and silicon oxide layers to expose electrical contacts. The photoresist layer and silicon nitride layers protect the magnetoresistive layers from exposure to oxygen during the etching into the silicon oxide layer.
