20100025742TRANSISTOR HAVING A STRAINED CHANNEL REGION CAUSED BY HYDROGEN-INDUCED LATTICE DEFORMATION - A lattice distortion may be achieved by incorporating a hydrogen species into a semiconductor material, such as silicon, without destroying the lattice structure. For example, by incorporating the hydrogen species on the basis of an electron shower, a tensile strain component may be obtained in the channel of N-channel transistors.02-04-2010
20110049585MAINTAINING INTEGRITY OF A HIGH-K GATE STACK BY PASSIVATION USING AN OXYGEN PLASMA - In semiconductor devices, integrity of a titanium nitride material may be increased by exposing the material to an oxygen plasma after forming a thin silicon nitride-based material. The oxygen plasma may result in an additional passivation of any minute surface portions which may not be appropriately covered by the silicon nitride-based material. Consequently, efficient cleaning recipes, such as cleaning processes based on SPM, may be performed after the additional passivation without undue material loss of the titanium nitride material. In this manner, sophisticated high-k metal gate stacks may be formed with a very thin protective liner material on the basis of efficient cleaning processes without unduly contributing to a pronounced yield loss in an early manufacturing stage.03-03-2011

20110271595DRIVE ARRANGEMENT FOR MOTOR-OPERATED ADJUSTMENT OF A CLOSURE ELEMENT IN A MOTOR VEHICLE - Disclosed herein is a drive arrangement for motor-operated adjustment of a closure element in a motor vehicle having at least one drive with a drive motor, and a drive controller. The closure element can be driven in the motor-operated adjustment mode by the drive motor in the closing direction and in the opening direction between a closed and an open position. The drive is non-self-locking and has a sensor, in particular a Hall sensor, for sensing the drive movement. The drive controller monitors the sensor signals for a fault state, and when a fault state is sensed initiates an emergency braking and/or stop mode. The drive arrangement comprises two drives each with a sensor for determining the respective drive movement. To detect fault-induced slamming shut of the closure element, the drive controller correlates the sensor signals of the two sensors, in particular compares said sensor signals.11-10-2011
