Title: Innovations by Chaopeng Chen
Introduction
Chaopeng Chen is a notable inventor based in Fremont, CA, with a focus on advancements in technology. He holds a total of 6 patents, showcasing his contributions to the field of engineering and materials science.
Latest Patents
One of his latest patents is a method of using xenon ion beams to improve track width definition. This innovative process involves using a beam of xenon ions along with a suitable mask to ion mill a stack until a thin layer, no more than about 0.1 microns thick, is removed. This results in the formation of a pedestal with sidewalls that include a vertical section and a shortened taper portion. The process is followed by the formation of conductive lead layers as needed. The use of xenon as the sputtering gas allows for more precise control over the milling termination point.
Another significant patent is the process to manufacture a magnetic tunnel junction (MTJ) read head. Similar to the previous method, this process utilizes a beam of xenon ions and a suitable mask to ion mill an MTJ stack. The milling removes a thin layer to create a pedestal with sidewalls that include all of the free layer. This is also followed by the formation of longitudinal bias and conductive lead layers. Again, the use of xenon as the sputtering gas enhances the precision of the milling process.
