Abstract: A method for fabricating a semiconductor device includes forming a gate electrode structure over a first region of a semiconductor substrate, and selectively forming an oxide layer overlying the gate electrode structure by reacting a halide compound with oxygen to increase a height of the gate electrode structure. The halide compound may be silicon tetrachloride, and the oxide layer may be silicon dioxide. The gate electrode structure may be a dummy gate electrode, which is subsequently removed, and replaced with another gate electrode structure.

Abstract: A resistance type touch panel includes a first substrate, a second substrate and a detection module. The first substrate further includes a touch module at a bottom surface thereof facing the second substrate, in which the touch module has a plurality of conductive blocks having individual signal lines. The second substrate includes a bias-layer module at an upper surface thereof opposing to the touch module by a predetermined spacing. The bias-layer module further includes at least four bias points accounted for at least two voltage biases along two directions. The detection module is electrically coupled with the signal lines of the touch module for realizing all the voltage changes among the conductive blocks.

Abstract: An automatic opening/closing mechanism is disclosed. It includes a coil spring, a pushing member, a driven member and a contact board which are disposed in a cylinder under a decorative article. A shaft is disposed at a center of the coil spring. One end of the shaft is connected with one end face of the pushing member. The pushing member has a disc-like shape. The other end face of the pushing member is disposed with several slope teeth which are slidably engaged with several slope recesses of one end of the driven member. The other end of the driven member abuts against the contact board. Two electric contacts are disposed beside the contact board. The power of coil spring is gradually released to rotate the pushing member so as to upward push the driven member for lifting the contact board to contact with the electric contacts and close the circuit. At this time, a bulb or a music box is turned on to emit light or music.
