Abstract:
Methods for forming fin structure with desired materials formed on different locations of the fin structure using a selective deposition process for three dimensional (3D) stacking of fin field effect transistor (FinFET) for semiconductor chips are provided. In one embodiment, a method of forming a structure with desired materials on a substrate includes forming a patterned self-assembled monolayer on a circumference of a structure formed on a substrate, wherein the patterned self-assembled monolayer includes a treated layer formed among a self-assembled monolayer, and performing an atomic layer deposition process to form a material layer predominantly on the self-assembled monolayer from the patterned self-assembled monolayer.
Abstract:
Methods are described for forming and treating a flowable silicon-carbon-and-nitrogen-containing layer on a semiconductor substrate. The silicon and carbon constituents may come from a silicon-and-carbon-containing precursor while the nitrogen may come from a nitrogen-containing precursor that has been activated to speed the reaction of the nitrogen with the silicon-and-carbon-containing precursor at lower deposition temperatures. The initially-flowable silicon-carbon-and-nitrogen-containing layer is ion implanted to increase etch tolerance, prevent shrinkage, adjust film tension and/or adjust electrical characteristics. Ion implantation may also remove components which enabled the flowability, but are no longer needed after deposition. Some treatments using ion implantation have been found to decrease the evolution of properties of the film upon exposure to atmosphere.
Abstract:
A method of forming shallow trench isolation on a substrate (152, 252, 1102, 1202, 1302) using a gas cluster ion beam (GCIB) (128, 1101, 1201, 1301) is described. The method comprises generating a GCIB (128, 1101, 1201, 1301), and irradiating the substrate (152, 252, 1102, 1202, 1302) with the GCIB (128, 1101, 1201, 1301) to form a shallow trench isolation structure (1100, 1200, 1300) by growing a dielectric layer (1114, 1204, 1312) in at least one region on the substrate (152, 252, 1102, 1202, 1302).

Species are supplied to a flowable layer over a substrate. A property of the flowable layer is modified by implanting the species to the flowable layer. The property comprises a density, a stress, a film shrinkage, an etch selectivity, or any combination thereof.
Abstract:
Methods for repairing low-k dielectrics using a plasma immersion carbon doping process are provided herein. In some embodiments, a method of repairing a low-k dielectric material disposed on a substrate having one or more features disposed through the low-k dielectric material may include depositing a conformal oxide layer on the low-k dielectric material and within the one or more features; and doping the conformal oxide layer with carbon using a plasma doping process.
