Abstract
Integrated circuits and methods for fabricating integrated circuits are provided. In one example, a method for fabricating an integrated circuit includes etching an enhanced high-aspect-ratio process (eHARP) oxide fill that is disposed in an STI trench between two adjacent fins to form a recessed eHARP oxide fill. The two adjacent fins extend from a bulk semiconductor substrate. A silicon layer is formed overlying the recessed eHARP oxide fill. The silicon layer is converted to a thermal oxide layer to further fill the STI trench with oxide material.
