Abstract:
A high-k metal gate electrode is formed with reduced gate voids. An embodiment includes forming a replaceable gate electrode, for example of amorphous silicon, having a top surface and a bottom surface, the top surface being larger than the bottom surface, removing the replaceable gate electrode, forming a cavity having a top opening larger than a bottom opening, and filling the cavity with metal. The larger top surface may be formed by etching the bottom portion of the amorphous silicon at greater temperature than the top portion, or by doping the top and bottom portions of the amorphous silicon differently such that the bottom has a greater lateral etch rate than the top.
Abstract:
Disclosed is a method for printing an image, comprising a step of rasterizing an image to be printed in view of a first resolution to generate a first data bitmap; a step of splitting the first data bitmap according to a ratio of the first resolution to a second resolution to generate second data bitmaps; and a step of outputting the second data bitmaps to a printer with the second resolution for printing. Disclosed is also a device for printing images. The method and device for printing an image may solve the problem in the prior art that the definition of an image printed from a printer is too low and improve the definition of an image printed from a printer.

Abstract:
The disclosure provides a match-rule based service message transfer method and system in the IPTV, to address the problems in the IPTV message system of message storing and backlog, low push efficiency and poor usability. In the disclosure, match fields are arranged in a set-top box and a service message to be sent, the service message is sent by means of broadcast or multicast, the set-top box performs matching for the match fields based on the match rule, and filters the message. The disclosure avoids sending a service message by means of unicast, increases the push efficiency and can greatly reduce the storage load of offline messages in a message system. The formed message may be sent according to a single or combined policy which depends on a specific service attribute, thereby greatly facilitating the service operation.
Abstract:
The gate and active regions of a device are formed and alternating steps of applying and removing nitride and oxide layers allows exposing silicon in different areas while keeping silicon or polysilicon in other area covered with nitride. Metal layers are deposited over the exposed silicon or polysilicon and annealing forms a silicide layer in the selected exposed areas. The oxide and/or nitride layers are removed from the covered areas and another metal layer is deposited. The anneal process is repeated with silicide of one thickness formed over the second exposed areas with additional thickness of silicide formed over the previous silicide thickness.
Abstract:
A method of fabricating a Schottky field effect transistor is provided that includes providing a substrate having at least a first semiconductor layer overlying a dielectric layer, wherein the first semiconductor layer has a thickness of less than 10.0 nm. A gate structure is formed directly on the first semiconductor layer. A raised semiconductor material is selectively formed on the first semiconductor layer adjacent to the gate structure. The raised semiconductor material is converted into Schottky source and drain regions composed of a metal semiconductor alloy. A non-reacted semiconductor material is present between the Schottky source and drain regions and the dielectric layer.
Abstract:
A semiconductor is formed on an SOI substrate, such as an extremely thin SOI (ETSOI) substrate, with increased extension thickness. Embodiments include semiconductor devices having an epitaxially formed silicon-containing layer, such as embedded silicon germanium (eSiGe), on the SOI substrate. An embodiment includes forming an SOI substrate, epitaxially forming a silicon-containing layer on the SOI substrate, and forming a gate electrode on the epitaxially formed silicon-containing layer. After gate spacers and source/drain regions are formed, the gate electrode and underlying silicon-containing layer are removed and replaced with a high-k metal gate. The use of an epitaxially formed silicon-containing layer reduces SOI thickness loss due to fabrication process erosion, thereby increasing extension thickness and lowering extension resistance.

Abstract:
A method for fabricating a nitrogen-containing dielectric layer and semiconductor device including the dielectric layer in which a silicon oxide layer is formed on a substrate, such that an interface region resides adjacent to substrate and a surface region resides opposite the interface region. Nitrogen is introduced into the silicon oxide layer by applying a nitrogen plasma. After applying nitrogen plasma, the silicon oxide layer is annealed. The processes of introducing nitrogen into the silicon oxide layer and annealing the silicon oxide layer are repeated to create a bi-modal nitrogen concentration profile in the silicon oxide layer. In the silicon oxide layer, the peak nitrogen concentrations are situated away from the interface region and at least one of the peak nitrogen concentrations is situated in proximity to the surface region. A method for fabricating a semiconductor device is incorporating the nitrogen-containing silicon oxide layers also disclosed.
