Title: The Innovations of Wen-yaung Lee
Introduction
Wen-yaung Lee is a prominent inventor based in San Jose, CA, known for his significant contributions to the field of magnetoresistive sensors. With a total of 16 patents to his name, Lee has made remarkable advancements in sensor technology that have implications for various applications.
Latest Patents
One of his latest patents is titled "Magnetoresistive sensor with sub-layering of pinned layers." This invention provides methods and apparatus for magnetoresistance sensors. A tunneling magnetoresistance (TMR) sensor may include configurations arranged as a top TMR stack. One of the two antiparallel layers of pinned layers within the TMR stack may be subdivided by a spacer layer. Tantalum may form the spacer layer that is inserted in a reference layer, which is one of the pinned layers and is located between a barrier layer and an antiparallel coupling layer that enables antiparallel coupling between the reference layer and a keeper layer of the pinned layers. The barrier layer deposited on a free layer of the TMR stacks separates the pinned layers from the free layer, allowing TMR effects to be detectable with the sensors. Another notable patent is "Magnetoresistive sensor with novel pinned layer structure." This invention features a magnetoresistive sensor having an antiparallel coupled pinned layer structure, including an APlayer and another APlayer. The APlayer consists of two ferromagnetic layers, AP() and AP(), with a separation layer sandwiched in between. The AP() layer is significantly larger than the AP() layer, resulting in strong pinning, while the separation layer provides increased TMR and reduced RA.
