  • Publication number: 20120241863
    Abstract: A fin field-effect transistor structure includes a substrate, a fin channel and a high-k metal gate. The high-k metal gate is formed on the substrate and the fin channel. A process of manufacturing the fin field-effect transistor structure includes the following steps. Firstly, a polysilicon pseudo gate structure is formed on the substrate and a surface of the fin channel. By using the polysilicon pseudo gate structure as a mask, a source/drain region is formed in the fin channel. After the polysilicon pseudo gate structure is removed, a high-k dielectric layer and a metal gate layer are successively formed. Afterwards, a planarization process is performed on the substrate having the metal gate layer until the first dielectric layer is exposed, so that a high-k metal gate is produced.

    Abstract: A method for fast resuming a computer system from a shutdown state is provided. The computer system comprises a basic input output system (BIOS), a system memory and a storage device storing a system memory data of the system memory and a used system memory block address table before the computer system enters the shutdown state. The method comprises receiving a starting signal for power supplying the computer system and starting the storage device. A fast boot built-in program of the BIOS is started and, according to the used system memory block address table, the fast boot built-in program sequentially reads the stored system memory data from the storage device and writes the read system memory data into the system memory with a use of an optimized read-and-write block size as a read-and-write unit. The computer system enters a suspended state and is resumed from the suspended state.

  • Publication number: 20120213272
    Abstract: In a method for adjusting video or audio quality of a video stream, a video stream request for requesting an original target video stream from a client is received. Then, information about a connection bandwidth of the client is obtained, and a step is performed for determining if the connection bandwidth of the client is sufficient for receiving the target video stream. When it is determined that the connection bandwidth of the client is insufficient, at least one video or audio parameter is selected according to the information about the connection bandwidth of the client to adjust and reduce the video or audio quality of the target video stream, and the quality-reduced target video stream is transmitted to the client. Information about connection bandwidth of the client is continually obtained for transmitting all of the target video stream to the client.

  • Patent number: 7675178
    Abstract: A method of fabricating a stacked structure for forming a damascene process is described. A doped dielectric layer is formed on a substrate. A surface treatment is performed to the dielectric layer to make the dopant concentration in an upper surface layer of the dielectric layer lower than that in the other portions of the dielectric layer. A metal hard mask is then formed on the dielectric layer. Since the dopant conc. in the upper surface layer of the dielectric layer is lowered, the reaction between the metal hard mask and the dopant in the dielectric layer can be inhibited.
