Latest Patents

One of Kuk Hyun Sunwoo's latest patents is for a film bulk acoustic resonator and method of forming the same. This innovative FBAR design includes an insulation layer on a substrate to prevent signal transmission to the substrate. The resonator features a membrane layer that is partially etched to adjust the resonance frequency band and improve transmission gain. The method of forming the FBAR involves creating a sacrificing layer made of polysilicon, utilizing a dry etching process to form an air gap, and establishing a via hole. This approach addresses structural issues found in conventional air gap forming processes and allows for controlled locations and numbers of via holes.

Another notable patent involves a film bulk acoustic resonator device that includes a membrane supporting layer situated between a substrate and a membrane layer, surrounding an air gap region. This supporting layer enhances the robustness of the structure. The substrate is designed with a first area and a second area, with the membrane supporting layer formed on the second area to create an air gap on the first area. The device also incorporates electrodes and a piezoelectric layer to facilitate its function.
