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 form second mandrel structures comprising the hardmask material and the gap fill material and the substrate is etched using the second mandrel structures as a mask to form fin structures.
Abstract:
A ring shaped body includes a top flat region, a ring inner side and a ring outer side. The ring inner side comprises an approximately vertical wall. A conformal protective layer comprising 40 mol % to less than 100 mol % of Y2O3 and above 0 mol % to less than 60 mol % of ZrO2 is disposed on at least the top flat region, the ring inner side and the ring outer side of the ring shaped body by ion assisted deposition. The protective layer has a first thickness of less than 300 μm on the top flat region and a second thickness on the vertical wall of the ring inner side, where the second thickness is 45-70% of the first thickness.

A method of manufacturing an article comprises providing a lid or nozzle for an etch reactor. Ion assisted deposition (IAD) is then performed to deposit a protective layer on at least one surface of the lid or nozzle, wherein the protective layer is a plasma resistant rare earth oxide film having a thickness of less than 300 μm and an average surface roughness of 10 micro-inches or less.
Abstract:
Embodiments of the present disclosure provide methods for forming nanowire structures with desired materials for three dimensional (3D) stacking of fin field effect transistor (FinFET) for semiconductor chips. In one example, a method of forming nanowire structures on a substrate includes in a suspended nanowire structure on a substrate, the suspended nanowire includes multiple material layers having a spaced apart relationship repeatedly formed in the suspended nanowire structure, wherein the material layer includes a coating layer coated on an outer surface of a main body formed in the material layer, selectively removing a first portion of the coating layer from the material layers to expose the underlying main body of the material layers while maintaining a second portion of the coating layer remaining on the material layers, laterally etching the main body of the material layers exposed by removal of the coating layer, and selectively growing film layers on the exposed main body of the material layer.
Abstract:
Embodiments may include a method of semiconductor patterning including forming a first trench bordered by a first spacer material. The method may involve forming a second trench bordered by a second spacer material formed conformally around the first spacer material. The method may include filling the second trench with a semiconductor material.
