  • Publication number: 20070251815
    Abstract: A method for manufacturing diamond-like carbon (DLC) film is disclosed. The method mainly includes steps of: (a) fixing a substrate in a reaction chamber; (b) pumping the pressure of the reaction chamber below 10?6 torr; (c) introducing at least a carbon-containing gas into the reaction chamber; and (d) depositing a diamond-like carbon film on the substrate by sputtering a graphite target. The deposited DLC film is in a shape of flakes. The appearance of the deposited DLC film on the surface of the substrate is in a rose-like shape. Moreover, the height of the deposited DLC film is of micrometer level, and the thickness of the deposited DLC film is of nanometer level. Since the aspect ratio of the deposited flake-shaped DLC film is high, the deposited DLC film can enhance the field emission.

  • Patent number: 7015136
    Abstract: A method for preventing formation of photoresist scum. First, a substrate on which a dielectric layer is formed is provided. Next, a non-nitrogen anti-reflective layer is formed on the dielectric layer. Finally, a photoresist pattern layer is formed on the non-nitrogen anti-reflective layer. During the formation of the photoresist pattern layer, the non-nitrogen anti-reflective layer does not react with the photoresist pattern layer, thus not forming photoresist scum. This prevents undesired etching profile and critical dimension (CD) change due to presence of photoresist scum. The non-nitrogen anti-reflective layer can be silicon-rich oxide (SiOx) or hydrocarbon-containing silicon-rich oxide (SiOxCy:H).
