Substrate-free integrated circuit structures

A computing device, comprising:

• a board;
• and
• a component coupled to the board, the component including a substrate-less integrated circuit structure, comprising:
• a fin;
• a plurality of gate structures over the fin;
• and
• a plurality of alternating P-type epitaxial structures and N-type epitaxial structures between adjacent ones of the plurality of gate structures.

A substrate-less integrated circuit structure, comprising:

• a first fin and a second fin on a sub-fin;
• first gate structures over the first fin, and second gate structures over the second fin;
• a P-type epitaxial structure within the first fin between adjacent ones of the first gate structures;
• an N-type epitaxial structure within the second between adjacent ones of the second gate structures;
• and
• a conductive layer on a side of the sub-fin opposite the first and second fins.
