Title: Innovations by Yunxiao Gao
Introduction
Yunxiao Gao is a prominent inventor based in Sunnyvale, CA, known for his contributions to the field of magnetic recording technologies. With a total of 5 patents to his name, he has made significant advancements that enhance the efficiency and effectiveness of various technologies.
Latest Patents
One of his latest patents is an in-situ method to reduce particle contamination in a vacuum plasma processing tool. This innovative method and apparatus allow for particle decontamination while a wafer is in a vacuum tool or deposition chamber, eliminating the need for additional devices. The technique is particularly effective for addressing particle contamination caused by tool resident mechanical components. Furthermore, this in-situ decontamination occurs in the presence of plasma, which helps maximize a 'self bias' voltage under RF conditions, integrating seamlessly into the vacuum process.
Another notable patent involves laminated high moment magnetic films with antiferromagnetic coupling as the write pole of a perpendicular magnetic recording head. This design features a main pole comprising high moment magnetic layers laminated with both soft magnetic layers and non-magnetic layers for antiferromagnetic coupling. The perpendicular write head includes a return pole connected to the main pole by a back gap closure at a distal end, separated from the main pole by a gap at the air bearing surface (ABS). A write coil is strategically positioned between the main pole and the return pole, with the surface area of the return pole at the ABS being substantially larger than that of the main pole.
