SEMICONDUCTOR DEVICE AND METHOD FOR FABRICATING THE SAME
First Claim
1. A method for fabricating semiconductor device, comprising:
- providing a substrate having a first fin-shaped structure on a first region and a second fin-shaped structure on a second region;
forming a plurality of first gate structures on the first fin-shaped structure, a plurality of second gate structures on the second fin-shaped structure, and an interlayer dielectric (ILD) layer around the first gate structures and the second gate structures;
forming a first patterned mask on the ILD layer and between the first region and the second region;
forming a second patterned mask on the second region; and
using the first patterned mask and the second patterned mask to remove all of the ILD layer from the first region and part of the ILD layer from the second region for forming a plurality of first contact holes in the first region and a plurality of second contact holes in the second region.
