    Abstract: A method for forming the semiconductor device structure is provided. The method includes forming a first metal layer over a substrate and forming a dielectric layer over the first metal layer. The method includes forming an antireflection layer over the dielectric layer, forming a hard mask layer over the antireflection layer and forming a patterned photoresist layer over the hard mask layer. The method includes etching a portion of the antireflection layer by performing a first etching process and etching through the antireflection layer and etching a portion of the dielectric layer by performing a second etching process. The method includes etching through the dielectric layer by performing a third etching process to form a via portion on the first metal layer. The via portion includes a first sidewall and a second sidewall, and the slope of the first sidewall is different from that of the second sidewall.

    Abstract: A semiconductor device includes a substrate, a first gate, a second gate, and an insulating structure. The substrate includes a first fin and a second fin. The first gate is disposed over the first fin. The second gate is disposed over the second fin. A gap is formed between the first gate and the second gate, and the gap gets wider toward the substrate. The insulating structure is disposed in the gap. The insulating structure has a top surface and a bottom surface opposite to each other. The bottom surface faces the substrate. An edge of the top surface facing the first gate is curved inward the top surface.
