    摘要: Provided is a contents providing system. The system includes a storing unit, a plurality of server nodes, a dispatcher node, and a storing/deleting management node. The storing unit stores synchronization data according to a service state of each contents data that can be provided. The plurality of server nodes change synchronization data of contents, and provides the contents service in response to a contents service request input via a network. The dispatcher node checks a service state of contents to select a server node that is to provide the corresponding contents service, and changes synchronization data to transmit address data of the selected server node and a corresponding contents file data to a client that has requested the contents service. The storing/deleting management node manages storing and deleting of contents data stored in a contents storing unit with reference to the synchronization data stored in the storing unit.

    摘要: A rapid thermal nitridation (RTN) process produces a nitrogen concentration gradient in an oxynitride layer to compensate for transistor threshold voltage effects from a thickness gradient in the oxynitride layer. The nitrogen concentration gradient is selected to allow greater dopant penetration through thicker gate dielectrics in PMOS transistors formed using the oxynitride layer. Any increases in threshold voltage due to thicker gate dielectrics are counteracted by corresponding decreases in threshold voltage due to dopant penetration, allowing consistent threshold voltage values to be maintained for all PMOS transistors on a single wafer. The nitrogen concentration gradient can be introduced by regulating the flow of nitrous oxide during RTN processing to cause an accumulation of atomic oxygen to develop within the process chamber. The atomic oxygen forms a concentration distribution that increases in the direction of nitrous oxide flow, and therefore removes incorporated nitrogen from the oxynitride layer in corresponding proportions.
