Abstract:
1. A method of forming a layer comprising epitaxial silicon, comprising: providing an opening within a first material received over a monocrystalline material; lining opposing sidewalls of the opening with a second material which is different in composition from the first material, monocrystalline material being exposed at a base of the opening between laterally spaced portions of the second material received within the opening; within a chamber, epitaxially growing a silicon-comprising layer from the exposed monocrystalline material within the second material-lined opening; within the same chamber in which the epitaxially growing occurs, in situ etching away at least a portion of the laterally spaced portions of the second material from the opening; and removing all of the first material within which the opening was provided from being received over the monocrystalline material and incorporating the epitaxially grown silicon-comprising layer into a channel region of a vertically oriented field effect transistor having one source/drain region received elevationally inward of the channel region and another source/drain region received elevationally outward of the channel region.
