Abstract:
An integrated circuit formed on a substrate having integrated isolation regions and active regions, the integrated circuit comprising:a plurality of isolation regions formed upon the substrate from a first dielectric layer residing upon the substrate and a second dielectric layer that resides upon the first dielectric layer;epitaxially grown active regions that have been grown upon the substrate and that are defined by voids that were etched from the first dielectric layer and the second dielectric layer and that also define the plurality of isolation regions, the sidewalls of the epitaxially grown active regions oriented substantially perpendicular to the surface of the substrate;an ion implant layer residing at the junction between the epitaxially grown active regions and the substrate, the ion implant layer preventing dopant diffusion from the substrate to the epitaxially grown active regions; anda plurality of transistors formed in and on the epitaxially grown active regions.
