Abstract

Memory cell structures, including PSOIs, NANDs, NORs, FinFETs, etc., and methods of fabrication have been described that include a method of epitaxial silicon growth. The method includes providing a silicon layer on a substrate. A dielectric layer is provided on the silicon layer. A trench is formed in the dielectric layer to expose the silicon layer, the trench having trench walls in the <100> direction. The method includes epitaxially growing silicon between trench walls formed in the dielectric layer.
