Various embodiments for improved power devices as well as their methods of manufacture, packaging and circuitry incorporating the same for use in a wide variety of power electronic applications are disclosed. One aspect of the invention combines a number of charge balancing techniques and other techniques for reducing parasitic capacitance to arrive at different embodiments for power devices with improved voltage performance, higher switching speed, and lower on-resistance. Another aspect of the invention provides improved termination structures for low, medium and high voltage devices. Improved methods of fabrication for power devices are provided according to other aspects of the invention. Improvements to specific processing steps, such as formation of trenches, formation of dielectric layers inside trenches, formation of mesa structures and processes for reducing substrate thickness, among others, are presented. According to another aspect of the invention, charge balanced power devices incorporate temperature and current sensing elements such as diodes on the same die. Other aspects of the invention improve equivalent series resistance (ESR) for power devices, incorporate additional circuitry on the same chip as the power device and provide improvements to the packaging of charge balanced power devices.

A dielectric antenna with an electromagnetic feed element (2) and with a lens (3) made of a dielectric material, the feed element (2) emitting electromagnetic radiation (4) and the lens (3) being supplied with electromagnetic radiation (4) in the feed region (5), the lens (3) relaying the electromagnetic radiation (4) and radiating it with the transmission region (6). To configure these dielectric antennas such that the disadvantages of the dielectric antennas known from the prior art are at least partially avoided, first of all, the lens (3) is shaped essentially ellipsoidally at least in the transmission region (6) and the lens (3) is arranged relative to the feed element (2) such that the electromagnetic radiation (4) emitted by the lens (3) in the direction of maximum radiation (7) of the antenna has an essentially planar phase front.

A rearview mirror display system for a vehicle including a rearview mirror assembly, a reflective element and a projection display. The rearview mirror assembly comprises a mirror casing. The reflective element is included at the casing and has a front and a back. The front is directed toward and viewable by a driver of the vehicle when the assembly is mounted in the vehicle. The projection display is positioned in the casing to the rear of the back of the reflective element. The reflective element comprises a transflective reflective element. An image projected by the projection display is viewable by a driver of the vehicle from the front of the transflective reflective element.

An apparatus and method for distracting, in a given direction, and supporting two tissue surfaces. A plurality of wafers are consecutively inserted between the two tissue surfaces to create a column of wafers. The column of wafers is oriented between the tissue surfaces so as to expand in the given direction as the wafers are consecutively added to the column.

The invention provides a method for obtaining local anesthetics encapsulated in liposomes, such as multivesicular liposomes, with high encapsulation efficiency and slow release in vivo. When the encapsulated anesthetic is administered as a single intracutaneous dose, the duration of anesthesia and half-life of the drug at the local injection site is increased as compared to injection of unencapsulated anesthetic. The maximum tolerated dose of the encapsulated anesthetic is also markedly increased in the liposomal formulation over injection of unencapsulated anesthetic. These results show that the liposomal formulation of local anesthetic is useful for sustained local infiltration and nerve block anesthesia.

A semiconductor power device includes a drift region of a first conductivity type, a well region extending above the drift region and having a second conductivity type opposite the first conductivity type, an active trench extending through the well region and into the drift region, source regions having the first conductivity type formed in the well region adjacent the active trench, and a first termination trench extending below the well region and disposed at an outer edge of an active region of the device. The sidewalls and bottom of the active trench are lined with dielectric material, and substantially filled with a first conductive layer forming an upper electrode and a second conductive layer forming a lower electrode, the upper electrode being disposed above the lower electrode and separated therefrom by inter-electrode dielectric material. The first termination trench can be lined with a layer of dielectric material that is thicker than the dielectric material lining the sidewalls of the active trench, and is substantially filled with conductive material.
