Patent ID: 7323374

Claim:
A method, comprising: providing a substrate having an insulating layer formed on a top surface of a bulk substrate and a single-crystal semiconductor layer formed on a top surface of said insulating layer; aligning a second fin pattern on a second photomask to a first fin pattern on a first photomask, said first fin pattern having first and second distal ends, said second fin pattern having first and second distal ends; overlapping said first end of said second fin pattern with said second end of said first fin pattern; forming a first fin of a first finFET in said semiconductor layer, said first fin of said first finFET defined by said first fin pattern; and forming a second fin of a second finFET in said semiconductor layer, said second fin of said second finFET defined by said second fin pattern, said forming said first fin and said forming said second fin include a same single etching of said semiconductor layer, said etching including forming a block from said semiconductor layer, said block integral with said first and second fins, said block defined by a block pattern on a third photomask, said block pattern aligned overlapping said first end of said second fin pattern and said second end of said first fin pattern.
