Latest Patents

Bing Yu's latest patents include groundbreaking methods for forming MEMS diaphragms that incorporate corrugations. One of his notable inventions describes a method of forming an acoustic transducer by providing a substrate and depositing a first structural layer on it. This layer is selectively etched to create an enclosed trench or pillar. A second structural layer is then deposited, featuring a depression or bump that corresponds to the trench or pillar. By heating the second structural layer above its glass transition temperature, it reflows, allowing for the creation of a diaphragm layer that includes corrugations. This innovative approach results in a diaphragm that is suspended over the substrate, enhancing the acoustic performance of the transducer.

Another significant patent involves a MEMS device with perimeter barometric relief pierce. This invention features a MEMS die that includes two diaphragms bounding a sealed chamber, with a stationary electrode positioned between them. A tunnel passes through both diaphragms, providing fluid communication while remaining sealed from the chamber. This design improves the functionality and efficiency of MEMS devices, showcasing Bing Yu's expertise in the field.
