Explain how asymmetric depositions can occur on a wafer in a sputter deposition system.

Asymmetric deposition means that thicker deposition occurs on one side of a feature (a step or side of a trench, for example) than the other.

Also suggest a way to decrease the asymmetry. Use schematic diagrams in your explanations.
