Abstract: A method for generating a layout pattern is provided. First, a layout pattern is provided to a computer system and is classified into two sub-patterns and a blank pattern. Each of the sub-patterns has pitches in simple integer ratios and the blank pattern is between the two sub-patterns. Then, a plurality of first stripe patterns and at least two second stripe patterns are generated. The edges of the first stripe patterns are aligned with the edges of the sub-patterns and the first stripe patterns have equal spacings and widths. The spacings or widths of the second stripe patterns are different from that of the first stripe patterns.

Abstract: A method for manufacturing a semiconductor device is provided. A first stack structure and a second stack structure are formed to respectively cover a portion of a first fin structure and a second fin structure. Subsequently, a spacer is respectively formed on the sidewalls of the fin structures through an atomic layer deposition process and the composition of the spacers includes silicon carbon nitride. Afterwards, a interlayer dielectric is formed and etched so as to expose the hard mask layers. A mask layer is formed to cover the second stack structure and a portion of the dielectric layer. Later, the hard mask layer in the first stack structure is removed under the coverage of the mask layer. Then, a dummy layer in the first stack structure is replaced with a conductive layer.

Abstract: A method of forming a semiconductor device includes the following steps. First of all, a substrate is provided, and a dielectric layer is formed on the substrate. Then, at least one trench is formed in the dielectric layer, to partially expose a top surface of the substrate. The trench includes a discontinuous sidewall having a turning portion. Next, a first deposition process is performed, to deposit a first semiconductor layer to fill up the trench and to further cover on the top surface of the dielectric layer. Following these, the first semiconductor layer is laterally etched, to partially remove the first semiconductor layer till exposing the turning portion of the trench. Finally, a second deposition is performed, to deposit a second semiconductor layer to fill up the trench.

Abstract: A method of fabricating a contact hole includes the steps of providing a conductive line, a mask layer covering and contacting the conductive line, a high-k dielectric layer covering and contacting the mask layer, and a first silicon oxide layer covering and contacting the high-k dielectric layer, wherein the high-k dielectric layer includes a first metal oxide layer, a second metal oxide layer and a third metal oxide layer stacked from bottom to top. A dry etching process is performed to etch the first silicon oxide layer, the high-k dielectric layer, and the mask layer to expose the conductive line and form a contact hole.
