Abstract: An electronic device can include a transistor structure, including a patterned semiconductor layer overlying a substrate and having a primary surface. The electronic device can further include first conductive structures within each of a first trench and a second trench, a gate electrode within the first trench and electrically insulated from the first conductive structure, a first insulating member disposed between the gate electrode and the first conductive structure within the first trench, and a second conductive structure within the second trench. The second conductive structure can be electrically connected to the first conductive structures and is electrically insulated from the gate electrode. The electronic device can further include a second insulating member disposed between the second conductive structure and the first conductive structure within the second trench. Processing sequences can be used that simplify formation of the features within the electronic device.

Abstract: In one embodiment, a method for forming a semiconductor device includes forming trench and a dielectric layer along surfaces of the trench. A shield electrode is formed in a lower portion of the trench and the dielectric layer is removed from upper sidewall surfaces of the trench. A gate dielectric layer is formed along the upper surfaces of the trench. Oxidation-resistant spacers are formed along the gate dielectric layer. Thereafter, an interpoly dielectric layer is formed above the shield electrode using localized oxidation. The oxidation step increases the thickness of lower portions of the gate dielectric layer. The oxidation-resistant spacers are removed before forming a gate electrode adjacent the gate dielectric layer.

Abstract: In an embodiment, a method of forming a semiconductor may include forming a plurality of active trenches and forming a termination trench substantially surrounding an outer periphery of the plurality of active trenches. The method may also include forming at least one active trench of the plurality of active trenches having corners linking trench ends to sides of active trenches wherein each active trench of the plurality of active trenches has a first profile along the first length and a second profile at or near the trench ends; and forming a termination trench substantially surrounding an outer periphery of the plurality of active trenches and having a second profile wherein one of the first profile or the second profile includes a non-linear shape.

Abstract: An electronic device can include a semiconductor layer having a primary surface, and a Schottky contact comprising a metal-containing member in contact with a horizontally-oriented lightly doped region within the semiconductor layer and lying adjacent to the primary surface. In an embodiment, the metal-containing member lies within a recess in the semiconductor layer and contacts the horizontally-oriented lightly doped region along a sidewall of the recess. In other embodiment, the Schottky contact may not be formed within a recess, and a doped region may be formed within the semiconductor layer under the horizontally-oriented lightly doped region and have a conductivity type opposite the horizontally-oriented lightly doped region. The Schottky contacts can be used in conjunction with power transistors in a switching circuit, such as a high-frequency voltage regulator.

Abstract: In one embodiment, a semiconductor device includes a multi-portion shield electrode structure formed in a drift region. The shield electrode includes a wide portion formed in proximity to a channel side of the drift region, and a narrow portion formed deeper in the drift region. The narrow portion is separated from the drift region by a thicker dielectric region, and the wide portion is separated from the drift region by a thinner dielectric region. That portion of the drift region in proximity to the wide portion can have a higher dopant concentration than other portions of the drift region.

Abstract: Traditional hand pump dispenser found in common household cannot dispense 100% of the product it contains in the container. This invention relates to devices, systems and methods for dispensing, distributing or delivering a substance from the dispensing container. More particularly, the invention relates to a device and method for dispensing a liquid (e.g., a cleaner, disinfectant, deodorizer, moisturizer, medication, etc.) more effectively. Furthermore, the invention allows users to access the dispensing material when the hand pump cannot be primed due to the level of the fluid in the container. This new dispensing bottle will eliminate waste to almost zero.
