  • Patent number: 7875511
    Abstract: A CMOS structure includes an n-FET device comprising an n-FET channel region and a p-FET device comprising a p-FET channel region. The n-FET channel region includes a first silicon material layer located upon a silicon-germanium alloy material layer. The p-FET channel includes a second silicon material layer located upon a silicon-germanium-carbon alloy material layer. The silicon-germanium alloy material layer induces a desirable tensile strain within the n-FET channel. The silicon-germanium-carbon alloy material layer suppresses an undesirable tensile strain within the p-FET channel region. A silicon-germanium-carbon alloy material from which is comprised the silicon-germanium-carbon alloy material layer may be formed by selectively incorporating carbon into a silicon-germanium alloy material from which is formed the silicon-germanium alloy material layer.

  • Patent number: 7220991
    Abstract: A black matrix having an opening at pixels of a matrix array in a display area, a common wire including common pads and common signal lines, and gate pads in a peripheral area, and an alignment key in outer area to align interlayer thin films are formed on an insulating substrate. Red, blue and green color filters the edge of which overlap the black matrix are formed at the pixels on the insulating substrate, and an organic insulating layer covering the black matrix and the color filters and having a contact hole exposing the gate pad is formed thereon. A gate wire including a gate line connected to the gate pad through the contact hole and a gate electrode connected to the gate line is formed on the organic insulating layer, and a gate insulating layer covering the gate wire is formed on the organic insulating layer. A semiconductor pattern and ohmic contact layers are sequentially formed on the gate insulating layer of the gate electrode.
