Abstract: A magnetic sensor device formed using SOI CMOS techniques includes a substrate, a silicon oxide layer and in some cases a plurality of gated regions. A first terminal is located between two innermost gated regions and supplies a supply voltage. A second and a third terminal, each of which is located between two adjacent gated regions other than the two innermost gated regions, output positive and negative Hall voltages. By appropriately controlling a bias voltage to the gated regions, small changes in a magnetic field induces larger currents in channel regions under the gated regions, which, in turn, results in detectable Hall voltages.

Abstract: A varactor has a plurality of alternating P− wells and N+ regions formed in a silicon layer. Each of the P− wells forms a first N+/P− junction with the N+ region on one of its side and a second N+/P− junction with the N+ region on the other of its sides. A gate oxide is provided over each of the P− wells, and a gate silicon is provided over each of the gate oxides. The potential across the gate silicons and the N+ regions controls the capacitance of the varactor.

Abstract: A browser-enabled system of software and services that focuses on connecting people across spatial, temporal, and organizational barriers to achieve specific objectives. The system includes a client server system that provides a virtual meeting place for a learning community and a structure through which that community can achieve its goals.

Abstract: A method is provided to form a LOCOS isolation in a CMOS SOI device. The SOI has a top silicon layer, a bottom silicon layer, and an insulation layer between the top and bottom silicon layers. An oxide layer is formed over the top silicon layer, and an LPCVD layer is deposited over the oxide layer. A photoresist is provided over the LPCVD layer that exposes a localized area of the LPCVD layer. The LPCVD layer and the oxide layer are etched away through the localized area to expose the top silicon layer. The silicon in the top silicon layer is etched so as to form a recess in the top silicon layer. The photoresist is removed and an isolation oxide is grown over the silicon in the recess so that the silicon in the recess is fully oxidized.

Abstract: A transistor has a gate, a source, and a drain. A spacer around the gate is etched so as to expose a top wall and at least a portion of a sidewall of the gate. Silicide layers contact the top wall and the exposed portion of the sidewall of the gate, the source, and the drain of the transistor.
