1. A method comprising:
- performing multiple cycles of an atomic layer deposition (ALD) process, wherein the performing of one cycle includes;
supplying a gas comprising SiH3N(C3H7)2 and O3 to a deposition chamber having a substrate to deposit a dielectric material over the substrate; and
supplying an O2 plasma to the deposition chamber after the supplying of the gas;
curing the deposited dielectric material using an ultra violet (UV) light; and
annealing the deposited dielectric material after the curing.
