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.

Abstract: Implementations described herein provide a pedestal lift assembly for a plasma processing chamber and a method for using the same. The pedestal lift assembly has a platen configured to couple a shaft of a pedestal disposed in the plasma processing chamber. An absolute linear encoder is coupled to a fixed frame wherein the absolute linear encoder is configured to detect incremental movement of the platen. A lift rod is attached to the platen. A motor rotor encoder brake module (MRBEM) is coupled to the fixed frame and moveably coupled to the lift rod, the motor encoder brake module configured to move the lift rod in a first direction and a second direction, wherein the movement of the lift rod results in the platen traveling vertically relative to the fixed frame.
