Abstract:
A semiconductor substrate has a trench extending from a front surface and including a lower part and an upper part. A first insulation layer lines the lower part of the trench, and a first conductive material in the lower part is insulated from the semiconductor substrate by the first insulating layer to form a field plate electrode of a transistor. A second insulating layer lines sidewalls of the upper part of said trench. A third insulating layer lines a top surface of the first conductive material at a bottom of the upper part of the trench. A second conductive material fills the upper part of the trench. The second conductive material forms a gate electrode of the transistor that is insulated from the semiconductor substrate by the second insulating layer and further insulated from the first conductive material by the third insulating layer.
Abstract:
A micro-sensor device that includes a passivation-protected ASIC module and a micro-sensor module bonded to a patterned cap provides protection for signal conditioning circuitry while allowing one or more sensing elements in the micro-sensor module to be exposed to an ambient environment. According to a method of fabricating the micro-sensor device, the patterned cap can be bonded to the micro-sensor module using a planarizing adhesive that is chemically compatible with the sensing elements. In one embodiment, the adhesive material is the same material used for the dielectric active elements, for example, a photo-sensitive polyimide film.

Abstract:
An integrated circuit transistor device includes a semiconductor substrate providing a drain, a first doped region buried in the semiconductor substrate providing a body and a second doped region in the semiconductor substrate providing a source. A trench extends into the semiconductor substrate and passes through the first and second doped regions. An insulated polygate region within the trench surrounds a polyoxide region that may have void inclusion. The polygate region is formed by a first gate lobe and second gate lobe on opposite sides of the polyoxide region. A pair of gate contacts are provided at each trench. The pair of gate contacts includes: a first gate contact extending into the first gate lobe at a location laterally offset from the void and a second gate contact extending into the second gate lobe at a location laterally offset from the void.
Abstract:
A photoresist delivery system includes a photoresist pump, a photoresist reservoir coupled to the photoresist pump, and a photoresist container. A control valve is between the photoresist reservoir and the photoresist container and is movable from a closed position to an open position upon engagement of the photoresist container with the photoresist reservoir to replenish photoresist therein.
