Latest Patents

One of her latest patents is titled "Embedded permeable polysilicon layer in MEMS device for multiple cavity pressure control." This invention discloses a process flow for forming a MEMS inertial measurement unit (IMU) that includes an accelerometer and a gyroscope, each located in separate sealed cavities maintained at different pressures. The formation of the MEMS IMU involves using a first very high-frequency (vHF) release to etch a sacrificial layer underneath a structural layer containing the accelerometer and gyroscope. The device is capped to set both cavities at a first pressure, and one of the cavity floors includes a gas permeable layer. The process further includes forming a chimney underneath the gas permeable layer and performing a second vHF release to etch through the gas permeable layer, allowing for different pressure settings in the cavities.

Another notable patent is for a thermoelectric generator. This device includes a substrate and one or more thermoelectric elements configured to convert a thermal drop across the elements into an electric potential via the Seebeck effect. The thermoelectric generator features a cavity between the substrate and the thermoelectric elements, along with a support structure that has lower thermal conductivity than the substrate, enhancing its efficiency.
