Abstract: Described herein are apparatuses, systems, and methods associated with metal-assisted transistors. A single crystal semiconductor material may be seeded from a metal. The single crystal semiconductor material may form a channel region, a source, region, and/or a drain region of the transistor. The metal may form the source contact or drain contact, and the source region, channel region, and drain region may be stacked vertically on the source contact or drain contact. Alternatively, a metal-assisted semiconductor growth process may be used to form a single crystal semiconductor material on a dielectric material adjacent to the metal. The portion of the semiconductor material on the dielectric material may be used to form the transistor. Other embodiments may be described and claimed.

Abstract: Transistors suitable for high voltage and high frequency operation. A nanowire is disposed vertically or horizontally on a substrate. A longitudinal length of the nanowire is defined into a channel region of a first semiconductor material, a source region electrically coupled with a first end of the channel region, a drain region electrically coupled with a second end of the channel region, and an extrinsic drain region disposed between the channel region and drain region. The extrinsic drain region has a wider bandgap than that of the first semiconductor. A gate stack including a gate conductor and a gate insulator coaxially wraps completely around the channel region, drain and source contacts similarly coaxially wrap completely around the drain and source regions.

Abstract: A single fin or a pair of co-integrated n- and p-type single crystal electronic device fins are epitaxially grown from a substrate surface at a bottom of one or a pair of trenches formed between shallow trench isolation (STI) regions. The fin or fins are patterned and the STI regions are etched to form a height of the fin or fins extending above etched top surfaces of the STI regions. The fin heights may be at least 1.5 times their width. The exposed sidewall surfaces and a top surface of each fin is epitaxially clad with one or more conformal epitaxial materials to form device layers on the fin. Prior to growing the fins, a blanket buffer epitaxial material may be grown from the substrate surface; and the fins grown in STI trenches formed above the blanket layer. Such formation of fins reduces defects from material interface lattice mismatches.
