Abstract: An electronic circuit includes a plurality of fin lines on a substrate and a plurality of gate lines with a first line width, crossing over the fin lines. The gate lines are parallel and have a plurality of discontinuous regions forming as a plurality of slots. A region of any one of the gate lines adjacent to an unbalance of the slots has a second line width smaller than the first line width.

Abstract: A fin-shaped structure forming process includes the following step. A first mandrel and a second mandrel are formed on a substrate. A first spacer material is formed to entirely cover the first mandrel, the second mandrel and the substrate. The exposed first spacer material is etched to form a first spacer on the substrate beside the first mandrel. A second spacer material is formed to entirely cover the first mandrel, the second mandrel and the substrate. The second spacer material and the first spacer material are etched to form a second spacer on the substrate beside the second mandrel and a third spacer including the first spacer on the substrate beside the first mandrel. The layout of the second spacer and the third spacer is transferred to the substrate, so a second fin-shaped structure and a first fin-shaped structure having different widths are formed respectively.

Abstract: A replacement gate process is disclosed. A substrate and a dummy gate structure formed on the substrate is provided, wherein the dummy gate structure comprises a dummy layer on the substrate, a hard mask layer on the dummy layer, spacers at two sides of the dummy layer and the hard mask layer, and a contact etch stop layer (CESL) covering the substrate, the spacers and the hard mask layer. The spacers and the CESL are made of the same material. Then, a top portion of the CESL is removed to expose the hard mask layer. Next, the hard mask layer is removed. Afterward, the dummy layer is removed to form a trench.
