  • Patent number: 11626817
    Abstract: A vortex-induced vibration wind energy harvesting device, including an array consisting of a plurality of oscillators and a plurality of piezoelectric microelectromechanical systems (MEMSs), is provided. An oscillator is mounted on each of the piezoelectric MEMSs. When any one of the oscillators is oscillated by and resonant with vortex shedding due to an incoming airflow, its vortices in the wake will enhance the oscillation of the downstream oscillators, so that overall oscillation of the oscillators in the array is strengthened. The piezoelectric MEMSs are deformed by the vibration of these oscillators to generate voltage and current to output. In the present invention, the oscillators are arranged closely. When the airflow passes the array, even weak airflow can generate periodic force and cause significant oscillation due to resonance. The MEMS can convert mechanical energy into electrical energy and output it in order to achieve the purpose of wind energy harvesting.

    Abstract: A method for increasing an oxide thickness at trench corner of an UMOSFET is provided, comprising providing an N-type substrate, and forming an N-type drift region, N-type and P-type heavily doped regions and P-type body therein. A trench is defined through lithography, and a pad oxide is formed along the trench through oxidation or deposition process. An oxidation barrier is formed upon the pad oxide. A thermal oxidation process is employed, so a corner oxide is effectively formed at the trench corner. After removing the pad oxide and oxidation barrier, various back-end processes are carried out to complete the transistor structure. The invention is aimed to increase oxide thickness near the trench bottom, and can be applied to high voltage devices, such as SiC. The conventional electric field crowding effect occurring at the trench corner is greatly solved, thus increasing breakdown voltages thereof.
