Abstract: A method for growing a dielectric layer on a substrate, in accordance with the present invention, includes the steps of providing a substrate having at least two crystallographic planes which experience different dielectric layer growth rates due to the at least two crystallographic planes. A first dielectric layer is grown on the at least two crystallographic planes such that the first dielectric layer has a first thickness on a first crystallographic plane and a second thickness on a second crystallographic plane. The first thickness is thicker than the second thickness for the first dielectric layer. Dopants are implanted through the first dielectric layer. A greater number of dopants are implanted in the substrate through the second thickness than through the first thickness of the first dielectric layer. The first dielectric layer is then removed. A second dielectric layer is grown at a same location as the removed first dielectric layer.
