  • Publication number: 20090023258
    Abstract: A method for manufacturing CMOS transistors includes an etching back process alternatively performed after the gate structure formation, the lightly doped drain formation, source/drain implantation, or SEG process to etch a hard mask layer covering and protecting a first type gate structure, and to reduce thickness deviation between the hard masks covering the first type gate structure and a second type gate structure. Therefore the damage to spacers, STIs, and the profile of the gate structures due to the thickness deviation is prevented.

  • Publication number: 20080283503
    Abstract: A method of processing nature pattern on expitaxial substrate, unlike the conventional method of processing regular pattern on expitaxial substrate (such as sapphire substrate) by lithography, wet etches a sapphire substrate directly to obtain a nature pattern, so as to simplify the fabrication process. Compared with the conventional way of processing pattern sapphire, the nature pattern sapphire substrate produced by the method can avoid voids between the interface of sapphire and GaN and apply this technology to a wired bond LED structure to increase the sidewall light extraction and improve the texture of the sapphire surface of a flip chip LED structure. In addition, this method also can be applied to a thin-GaN LED for achieving the surface texture after the sapphire is removed by laser.

  • Patent number: 6700932
    Abstract: A system and method for editing a bitstream is provided. A first segment is cut from a first bitstream and a second segment is cut from a second bitstream. In cutting the segments from the bitstreams, first and last GOPs in the segments can be cut between frames in the GOP. The number of frames of the broken GOP is then compared to a pre-determined threshold value. If the number of frames of the broken GOP is less than or equal to the threshold value, the broken GOP is combined with a neighboring GOP. Therefore, the newly created GOP is longer than the standard size regular GOP. However, if the number of frames in the broken GOP is greater than the threshold value, a new GOP is created with the frames of the broken GOP. Therefore, the newly created GOP is shorter than the standard size regular GOP.

  • Patent number: 6544849
    Abstract: A method of fabricating the semiconductor device for preventing polysilicon line from being damaged during removal of a photoresist layer. The method begins by forming polysilicon lines on a core device region and an electrostatic discharge protection device region of a substrate. A plurality of offset spacers is formed on sidewalls of the polysilicon lines. After the offset spacers are formed, a photoresist layer is formed over the substrate to cover the core device region, while exposing the electrostatic discharge protection device region. With the photoresist layer serving as a mask, a punch-through ion implantation is performed on the electrostatic discharge protection device region before the photoresist layer is removed. Next, a plurality of lightly doped source/drain regions is formed in the core device region. A spacer is further formed on the edge of the offset spacer, followed by forming source/drain regions in the core device region and the electrostatic discharge protection device.

  • Patent number: 6127212
    Abstract: The present invention provides a method for forming a CMOS transistor on a semiconductor wafer. The semiconductor wafer comprises a substrate, a first gate positioned on the substrate being used to form a PMOS transistor of the CMOS transistor, and a second gate positioned on the substrate being used to form an NMOS transistor of the CMOS transistor. First spacers are formed on both lateral surfaces of the first gate and of the second gate. A first ion implantation process is performed to form a pair of first doped regions in the substrate, oppositely adjacent to the first gate, the pair of first doped regions to serve as heavy doped drain (HDD) of the PMOS transistor. Then the thickness of the first spacers is reduced. A second ion implantation process is performed to form a pair of second doped regions in the substrate, oppositely adjacent to the second gate, the pair of second doped regions to serve as the HDD of the NMOS transistor. Second spacers are then formed covering each first spacer.
