Abstract: Methods of reducing the SC GH on a FinFET device while protecting the LC devices and the resulting devices are provided. Embodiments include forming an ILD over a substrate of a FinFET device, the ILD having a SC region and a LC region; forming a SC gate and a LC gate within the SC and LC regions, respectively, an upper surface of the SC and LC gates being substantially coplanar with an upper surface of the ILD; forming a lithography stack over the LC region; recessing the SC gate; stripping the lithography stack; forming a SiN cap layer over the SC and LC regions; forming a TEOS layer over the SiN cap layer; and planarizing the TEOS layer.

Abstract: Disclosed is a method of forming a semiconductor structure that includes one or more fin-type field effect transistors (FINFETs) and single-diffusion break (SDB) type isolation regions that are within a semiconductor fin and that define the active device region(s) for the FINFET(s). The isolation regions are formed so that they include a semiconductor liner. The semiconductor liner ensures that, when a source/drain recess is formed immediately adjacent to the isolation region, the bottom and opposing sides of the source/drain recess will have semiconductor surfaces onto which epitaxial semiconductor material for a source/drain region is grown. As a result, the angle of the top surface of the source/drain region relative to the top surface of the semiconductor fin is minimized. Thus, the risk that a subsequently formed source/drain contact will not reach the source/drain region is also minimized. Also disclosed is a semiconductor structure formed according to the method.

Abstract: Methods for fabricating integrated circuits are provided. In one example, a method for fabricating an integrated circuit includes forming an isolation trench between two fin structures on an integrated circuit substrate, forming a flowable film in the isolation trench using a flowable chemical vapor deposition process, and annealing the flowable film to form a silicon oxide dielectric layer in the isolation trench. The annealing is performed at a temperature of less than about 200° C. with a process gas including N2 and H2O2.
