    摘要: In a method for forming FinFETs, a photo resist is formed to cover a first semiconductor fin in a wafer, wherein a second semiconductor fin adjacent to the first semiconductor fin is not covered by the photo resist. An edge of the photo resist between and parallel to the first and the second semiconductor fins is closer to the first semiconductor fin than to the second semiconductor fin. A tilt implantation is performed to form a lightly-doped source/drain region in the second semiconductor fin, wherein the first tilt implantation is tilted from the second semiconductor fin toward the first semiconductor fin.

The method further includes forming a material layer on the semiconductor substrate and the patterned mask layer, wherein the material layer substantially fills in the second opening; performing a first etching process self-aligned to remove the material layer within the first opening such that the semiconductor substrate within the first opening is exposed; performing a second etching process to etch the semiconductor substrate within the first opening, forming a first trench in the inter-device region; and thereafter performing a third etching process to remove the material layer in the second opening.
