Abstract: A powered vanity system with a power outlet positioned on the bottom of a drawer box adjacent a face plate with a pressure switch the prevents the flow of electricity to the power outlet when the drawer box is in a closed position and allows the flow of electricity to the power outlet when the drawer box is in an open position. A cable manager controls the power cord as the drawer box moves between open and closed positions. The drawer box is easily removable from the cabinet carcass and provides for a novel convenience lighting system.

Abstract: A lateral DMOS device with peak electric field moved below a top surface of the device along a body-drain junction is introduced. The LDMOS has a deep body and a drift region formed by a series of P-type and N-type implants, respectively. The implant doses and depths are tuned so that the highest concentration gradient of the body-drift junction is formed below the surface, which suppresses the injection and trapping of hot holes in the device drain-gate oxide region vicinity, and the associated device performance changes, during operation in breakdown.

Abstract: A method of forming and planarizing a deep isolation trench in a silicon-on-insulator (SOI) structure begins with a base semiconductor substrate, a buried insulator layer formed on the base semiconductor substrate, and an active silicon layer formed on the buried insulator layer. First, an ONO layer is formed on the active silicon layer. The ONO layer includes a layer of field oxide, a first layer of silicon nitride and a layer of deposited hardmask oxide. A trench having sidewalls that extend to the buried oxide layer is formed. A layer of trench lining oxide is then formed on the exposed sidewalls of the trench. Then, a second layer of silicon nitride is conformally formed on the substrate.
