  • Publication number: 20100007251
    Abstract: A supporting device of the invention comprises a main body, a shaft, and a rotating component. The main body comprises a sliding path and an opening. The shaft and the rotating component can slide along the sliding path. The rotating component is connected to the shaft. The shaft and at least a part of the rotating component can then be extended beyond the main body through the opening. Through the aforementioned configuration, the shaft can rotate with respect to the main body when the shaft and at least a part of the rotating component are extended beyond the main body.

  • Publication number: 20070166936
    Abstract: A salicide process is described, wherein a substrate with an NMOS transistor and a PMOS transistor thereon is provided. A mask layer is formed over the substrate covering the PMOS transistor but exposing the NMOS transistor, and then a pre-amorphization implantation (PAI) step is conducted to the substrate using the mask layer as a mask. After the mask layer is removed, a salicide layer is formed on the NMOS transistor and the PMOS transistor.

  • Publication number: 20020111005
    Abstract: A method of forming a contact pad on a semiconductor wafer is achieved. A first photoresist layer is formed on the surface of a substrate, expect in a region where the contact pad will be formed. A nitrogen ion implantation is performed on the substrate uncovered by the first photoresist layer, followed by the complete removal of the first photoresist layer. Next, a silicon oxide layer is grown on the substrate, except in the region for the formation of the contact pad. Two adjacent MOS transistors are formed on the silicon oxide layer. A conductive layer is formed on the surface of the substrate to cover the two MOS transistors as well as to fill in the gap between the two MOS transistors. A patterned second photoresist layer is subsequently formed on the surface of the conductive layer to define the patterns of the contact pad.

  • Patent number: 6368964
    Abstract: The present invention provides a method of reducing resistance in an Al-containing conductor. An Al oxide layer is first formed on the surface of an Al-containing conductor followed by the formation of a Ti layer and a barrier layer above the Al oxide layer, respectively. Finally, a W contact plug is formed within the barrier layer. The Al oxide layer functions in preventing a reaction between the Ti layer and the conductor during high temperature formation of the W contact plugs to avoid the influence of resistance in the Al-containing conductor.
