  • Publication number: 20130183804
    Abstract: A method for fabricating a MOS device is described. A first hard mask layer is formed over a substrate. The first hard mask layer is patterned and a portion of the substrate removed to form a first patterned hard mask, and a fin structure surrounded by a trench and extending in a first direction. An insulating layer is formed at the trench bottom. A gate conductive layer is formed on the insulating layer, extending in a second direction. A first implant process is performed using the first patterned hard mask as a mask to form first S/D extension regions in the sidewalls of the fin structure. The first patterned hard mask is removed to expose the top of the fin structure, and then a second implant process is performed to form second S/D extension region therein.

  • Publication number: 20130105867
    Abstract: A method of fabricating a field effect transistor with a fin structure is described. At least a fin structure is formed on a substrate. A planar insulation layer covering the fin structure is formed. A trench is formed in the insulation layer and intersects the fin structure both lengthwise, and thereby an upper portion of the fin structure is exposed to the trench. The exposed upper portion of the fin structure will serve as a gate channel region. A gate structure covering the upper portion is formed within the trench. The upper portion of the fin structure may be further trimmed. Accordingly, the present invention also relates to a field effect transistor with a fin structure, in which, the channel width is less than the source/drain width, and a gate structure has two sidewalls contacting two opposite sidewalls of a source region and a drain region, respectively.

  • Publication number: 20120132869
    Abstract: In an electric contact material of silver matrix capable of resisting arc erosion and containing no cadmium-composite, an Ag—(SnO2+In2O3) composite containing 9˜11% of (SnO2+In2O3) or an Ag—Cu oxide, composite containing 15˜25% of Cu oxide is used. The electrical contact material has a contact resistance of 5˜60 milliohms (mohm) and an arc erosion resistance capability up to 2*103˜10*103 times provided that the Vickers hardness (Hv) of the material is 100˜150, the measured current is 1˜5 amperes, and the measured voltage is 10˜20 volts. Two electrical contacts maintain an arc erosion resisting capability at the condition of a low contact resistance when the electrical contact material is formed on a surface of a metal substrate of an electric connector.

A second BARC layer is formed to fill the first trench structure and to cover the surface of the dielectric hard mask layer. A second photoresist layer is formed over the second BARC layer. The patterned second photoresist layer is used as a mask during an etch process to form a first via structure. The first trench structure and the first via structure are etched to obtain a second trench structure and a second via structure.

  • Publication number: 20090003226
    Abstract: A network intermediary device which determines the connection status with remote network intermediary devices by means of generating continuously connection test packets at same or different time intervals. When one remote network intermediary device does not receive the connection test packets within a predetermined timeout interval or has received fragged or damaged packets, the connection between the local network intermediary device and the remote network intermediary device is determined to be abnormal.

  • Patent number: 6124200
    Abstract: A method of fabricating an unlanded via. A substrate has a metal layer formed thereon and an ARC layer is formed on the metal layer. A liner dielectric layer is formed on the ARC layer and the sidewall of the metal layer, and an insulating material layer is formed on the insulating dielectric layer. The insulating material layer is then etched back, so a surface of the insulating material layer lower than the ARC layer surface is formed. Thereafter, a protective layer is formed on the insulating material layer and the metal layer, in which the protective layer is different from the liner dielectric layer. An IMD layer is formed on the protective layer. Using the liner dielectric layer as an etching stop layer, the IMD layer and the protective layer are patterned, and then the liner dielectric layer on the metal layer is removed, such that an unlanded via opening is formed.
