Abstract
Methods form epitaxial materials by forming at least two gate stacks on a silicon substrate and forming sidewall spacers on sides of the gate stacks. Such methods pattern a recess in the silicon substrate between adjacent ones of the gate stacks. The methods also provide a liner in a bottom of the recess, and epitaxially grow epitaxial material from sidewalls of the recess to fill the recess with the epitaxial material.
