Abstract:
The present disclosure provides methods for forming a metal containing material onto a substrate with good film uniformity and stress profile across the substrate. In one embodiment, a method of sputter depositing a metal containing layer on a substrate includes supplying a gas mixture into a processing chamber, forming a first portion of a metal containing layer on a substrate, transferring the substrate from the processing chamber, rotating the substrate, transferring the substrate back to the processing chamber, and forming a second portion of the metal containing layer on the first portion of the metal containing layer.
