Abstract: A method for fabricating a semiconductor device includes the following steps. First, a first interlayer dielectric is formed on a substrate. Then, a gate electrode is formed on the substrate so that the periphery of the gate electrode is surrounded by the first interlayer dielectric. Afterwards, a patterned mask layer is formed on the gate electrode, and a bottom surface of the patterned mask layer is level with a top surface of the first interlayer dielectric. A spacer is then formed on each sidewall of the gate electrode. Subsequently, a second interlayer dielectric is formed to cover a top surface and each side surface of the patterned mask layer. Finally, a self-aligned contact structure is formed in the first interlayer dielectric and the second interlayer dielectric.

Abstract: A method of generating a layout pattern including a FinFET structure layout includes the following processes. First, a layout pattern, which includes a sub-pattern having pitches in simple integer ratios, is provided to a computer system. The sub-pattern is then classified into a first sub-pattern and a second sub-pattern. Afterwards, first stripe patterns and at least one second stripe pattern are generated. The longitudinal edges of the first stripe patterns are aligned with the longitudinal edges of the first sub-pattern and the first stripe patterns have equal spacings and widths. The positions of the second stripe patterns correspond to the positions of the blank pattern, and spacings or widths of the second stripe patterns are different from the spacings or widths of the first stripe patterns. Finally, the first stripe patterns and the second stripe pattern are outputted to a photomask.
