    Abstract: Embodiments described herein relate to substrate processing methods. The methods include forming a patterned hardmask material on a substrate, forming first mandrel structures on exposed regions of the substrate, and depositing a gap fill material on the substrate over the hardmask material and the first mandrel structures. The first mandrel structures are removed to expose second regions of the substrate and form second mandrel structures comprising the hardmask material and the gap fill material. Fin structures are deposited on the substrate using the second mandrel structures as a mask.

    Abstract: Methods for forming semiconductor devices, such as FinFETs, are provided. In an embodiment, a fin structure processing method includes removing a portion of a first fin of a plurality of fins formed on a substrate to expose a surface of a remaining portion of the first fin, wherein the fins are adjacent to dielectric material structures formed on the substrate; performing a deposition operation to form features on the surface of the remaining portion of the first fin by depositing a Group III-V semiconductor material in a substrate processing environment; and performing an etching operation to etch the features with an etching gas to form a plurality of openings between adjacent dielectric material structures, wherein the etching operation is performed in the same chamber as the deposition operation.

    Abstract: A method for etching a dielectric layer disposed on a substrate is provided. The method includes de-chucking the substrate from an electrostatic chuck in an etching processing chamber, and cyclically etching the dielectric layer while the substrate is de-chucked from the electrostatic chuck. The cyclical etching includes remotely generating a plasma in an etching gas mixture supplied into the etching processing chamber to etch the dielectric layer disposed on the substrate at a first temperature. Etching the dielectric layer generates etch byproducts. The cyclical etching also includes vertically moving the substrate towards a gas distribution plate in the etching processing chamber, and flowing a sublimation gas from the gas distribution plate towards the substrate to sublimate the etch byproducts. The sublimation is performed at a second temperature, wherein the second temperature is greater than the first temperature.
