Abstract:
A method for forming FinFETs comprises forming a plurality of first fins and a plurality of second fins over a substrate and embedded in isolation regions, depositing a first photoresist layer over the substrate, removing the first photoresist layer over an n-type region, applying a first ion implantation process to the first isolation regions, wherein dopants with a first polarity type are implanted in the first isolation regions, depositing a second photoresist layer over the substrate, removing the second photoresist layer over a p-type region, applying a second ion implantation process to the second isolation regions, wherein dopants with a second polarity type are implanted in the second isolation regions, applying an annealing process to the isolation regions and recessing the first isolation regions and the second isolation regions through an etching process.

Claim (Index 1):
A semiconductor device comprising:\n a first fin and a second fin over a substrate; a first isolation region between the first fin and the second fin, the first isolation region comprising:\n a first concentration of a first type of dopants; \n a second concentration of a second type of dopants different from the first type of dopants; and \n an interface between the first concentration of the first type of dopants and the second concentration of the second type of dopants; \n a step on a top surface of the first isolation region, a sidewall of the step being located directly over the interface, wherein an upper portion of the first fin is of a first height, and wherein an upper portion of the second fin is of a second height, and wherein the first height is greater than the second height, wherein the second height is measured from a top surface of the second fin to a top surface of the first isolation region.
