Classification: CPC H | IPC H

Claim 7:
8. A method of manufacturing a semiconductor device, the method comprising:
forming a first semiconductor fin and a second semiconductor fin over a semiconductor substrate;
forming a first liner adjacent to both the first semiconductor fin and the second semiconductor fin;
forming a second liner over the first liner;
forming a third liner over the second liner, the third liner comprising nitrogen at a percentage of less than about 10%;
forming a fourth liner over the third liner;
forming a capping layer over the fourth liner, the capping layer comprising carbon at a percentage of less than about 10%; and
depositing a dielectric cap over the capping layer, wherein the first semiconductor fin extends further away from the semiconductor substrate than the dielectric cap.
