    Abstract: Methods and apparatus for deposition processes are provided herein. In some embodiments, an apparatus may include a substrate support including a susceptor plate having a pocket disposed in an upper surface of the susceptor plate and having a lip formed in the upper surface and circumscribing the pocket, the lip configured to support a substrate on the lip; and a plurality of vents extending from the pocket to the upper surface of the susceptor plate to exhaust gases trapped between the backside of the substrate and the pocket when a substrate is disposed on the lip. Methods of utilizing the inventive apparatus for depositing a layer on a substrate are also disclosed.

    Abstract: A method of forming a semiconductor device includes: forming a superlattice structure atop the top surface of a substrate, wherein the superlattice structure comprises a plurality of first layers and a corresponding plurality of second layers alternatingly arranged in a plurality of stacked pairs; forming a lateral etch stop layer by epitaxial deposition of a material of the first layer or the second layer of the superlattice structure atop a sidewall of the superlattice structure, or by selectively oxidizing edges of the first layers and second layers of the superlattice structure; subsequently forming a source region adjacent a first end of the superlattice structure and a drain region adjacent a second opposing end of the superlattice structure; and selectively etching the superlattice structure to remove each of the first layers or each of the second layers to form a plurality of voids in the superlattice structure.
