Latest Patents

Ming Gao holds a patent titled "Methods for reducing surface defects in active film layers." This patent outlines a method for reducing surface defects in piezoelectric film layers. The process involves several key steps, including the deposition of a first seed layer on a substrate, followed by an intermediate film layer deposited at temperatures ranging from approximately 350 degrees Celsius to 700 degrees Celsius. A second seed layer is then applied, and finally, a piezoelectric film layer is deposited at a lower temperature of less than 200 degrees Celsius. This innovative method ensures that the piezoelectric film layer maintains a surface cone defect count of less than or equal to 2 per 100 microns of surface area. Notably, the process is designed to avoid vacuum breaks between the depositions, enhancing the overall quality of the film layers.
