Abstract:
A metal gate structure is disclosed. The metal gate structure includes: a semiconductor substrate having an active region and an isolation region; an isolation structure disposed in the isolation region; a first gate structure disposed on the active region; and a second gate structure disposed on the isolation structure, wherein the height of the second gate structure is different from the height of the first gate structure.
Abstract:
A method for forming a semiconductor element structure is provided. First, a substrate including a first MOS and a second MOS is provided. The gate electrode of the first MOS is connected to the gate electrode of the second MOS, wherein the first MOS includes a first high-K material and a first metal for use in a first gate, and a second MOS includes a second high-K material and a second metal for use in a second gate. Then the first gate and the second gate are partially removed to form a connecting recess. Afterwards, the connecting recess is filled with a conductive material to form a bridge channel for electrically connecting the first metal and the second metal.
Abstract:
A semiconductor device and a method of fabricating the same are described. A substrate having a PMOS area and an NMOS area is provided. A high-k layer is formed on the substrate. A first cap layer is formed on the high-k layer in the PMOS area, and a second cap layer is formed on the high-k layer in the NMOS area, wherein the first cap layer is different from the second cap layer. A metal layer and a polysilicon layer are sequentially formed on the first and second cap layers. The polysilicon layer, the metal layer, the first cap layer, the second cap layer and the high-k layer are patterned to form first and second gate structures respectively in the PMOS and NMOS areas. First source/drain regions are formed in the substrate beside the first gate structure. Second source/drain regions are formed in the substrate beside the second gate structure.
Abstract:
A wafer has a trench, a STI layer formed in the trench, an HfO2-containing gate dielectric covering the wafer and the STI layer, a gate electrode formed on the HfO2-containing gate dielectric, and at least a spacer formed beside the gate electrode. The wafer is preheated and a bromine-rich gas plasma is provided to remove portions of the HfO2-containing gate dielectric.
Abstract:
The present invention provides a curable polyphenylene ether (PPE) resin, a composition made therefrom, and a process for preparing the resin. The process involves introducing a vinyl group-containing functional group to the terminal end of PPE by modifying the hydroxy and ester groups on the terminal end. Thus, a curable thermosetting PPE resin including a vinyl group on the terminal end can be obtained. Since the dehydrogenation of side chain methyl using n-BuLi is not conducted in the process of the present invention, the process is much easier, and the cost can be decreased.
Abstract:
A method of ultrasonic welding of plastic members to form a high strength interconnection between the members in the form of a low profile, illuminated electrical plug. High-frequency (ultrasonic) energy is transmitted by the ultrasonic welding apparatus to compatible plastic parts of the low profile electrical plug. At the intersection of the two parts, a combination of applied force and surface and/or intermolecular friction increases the temperature until the melting point of the thermoplastic is reached. Upon removal of the ultrasonic energy, a bond is produced between the plastic parts, effectively affixing them together in the desired fashion.
Abstract:
A one-piece tape cutting device is provided, comprising: a tape shaft, a tape pressing part, a cutting part, a tape supporting part, a side plate, and a pressing plate, and all are integrally formed without being connected by any fasteners. the tape is sleeved on the outside of the tape shaft from the opposite side of the side plate, the pressing plate is stretched by the tape and away from the tape shaft, so that the tape is pressed by the pressing plate and does not rotate, the tape is restricted by the anti-dislodging piece and does not disengage, and the end of the tape is pulled through the gap between the tape supporting part and the tape pressing part, and non-adhesive surface of the tape faces the tape pressing part, and the cutting part can cut through the tape.
