  • Patent number: 7514014
    Abstract: A method for depositing dielectric material into gaps between wiring lines in the formation of a semiconductor device includes the formation of a cap layer and the formation of gaps into which high density plasma chemical vapor deposition (HDPCVD) dielectric material is deposited. First and second antireflective coatings may be formed on the wiring line layer, the first and second antireflective coatings being made from different materials. Both antireflective coatings and the wiring line layer are etched through to form wiring lines separated by gaps. The gaps between wiring lines may be filled using high density plasma chemical vapor deposition.

  • Patent number: 7418609
    Abstract: A method for instant on multimedia playing is provided, which enables a computer to selectively enter an operation mode of an IOMP (Instant On Multimedia Player) program when it enters a power conservation mode. First, a computer system stays in the power conservation mode, until an IOMP activating signal has been received. Next, the computer system saves the hardware information of the computer into a memory. And then a processor of the computer reads an IOMP program from another memory and executes the IOMP program to produce and display a human-computer interface menu, which is provided for users to select files for playing. Next, the processor executes the IOMP program to play the files selected previously. Finally, upon the receipt of a recovery instruction, the computer system saves the hardware information back into the computer to recover the computer to the power conservation mode.

  • Publication number: 20060286794
    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.

  • Publication number: 20060281299
    Abstract: A dielectric layer overlying a substrate is prepared. A damascene opening is etched into the dielectric layer. The damascene opening is filled with copper or copper alloy. A surface of the copper or copper alloy is treated with hydrogen-containing plasma such as H2 or NH3 plasma. The treated surface of the copper or copper alloy then reacts with trimethylsilane or tertramethylsilane under plasma enhanced chemical vapor deposition (PECVD) conditions. Subsequently, by PECVD, a silicon carbide layer is in-situ deposited on the copper or copper alloy.
