  • Patent number: 7625800
    Abstract: A method for fabricating a MOS transistor is suitable for modifying the configuration of a gate electrode. The method includes coating a first oxide layer on a semiconductor substrate and removing a predetermined width of the first oxide layer; forming an LDD region in the substrate; forming a gate spacer on the substrate; forming a channel in the LDD region, forming a gate oxide layer; forming a polysilicon gate electrode; and forming source/drain diffusion regions. Accordingly, a line width of the gate electrode can be reduced without employing lithography of high precision, and an area reserved for salicide can be maximally secured on the gate and source/drain regions.

  • Publication number: 20090044164
    Abstract: Disclosed is a method for placing dummy patterns in a semiconductor device layout. More specifically, the method places the dummy patterns densely between main patterns in accordance with a sequence and configuration. The method includes placing vertical dummies having a greater length than width in a region other than main patterns to form a first layout, removing the vertical dummies within a first distance from the main patterns to form a second layout, placing horizontal dummies having a greater length than width in a vacant space of the second layout to form a third layout, and removing the horizontal dummies within a second distance from the main patterns in the third layout. The method prevents and/or inhibits pattern deformation.

  • Publication number: 20090026624
    Abstract: A method for manufacturing a metal line of a semiconductor device includes forming an interlayer dielectric layer over the whole surface of a semiconductor substrate including a first metal line. A plurality of trenches are formed in trench areas each having a predetermined depth from a surface thereof by selectively removing portions of the interlayer dielectric layer. A first metal film is formed in the plurality of trenches. A first photoresist pattern is formed over the interlayer dielectric layer exposing contact areas and the first metal line. Via holes are formed in the contact areas by etching the interlayer dielectric layer using the first photoresist pattern and the first metal film as masks. A second metal film is formed in the via holes. Accordingly, misalignment of masks caused during formation of the metal line can be restrained, thereby minimizing the defect rate and improving yield.
