Abstract
Methods and apparatus for control of the quality of films deposited via physical vapor deposition are provided herein. In some embodiments, a method of depositing a film using linear scan physical vapor deposition includes: determining a deposition rate of a material to be deposited on a substrate in a linear scan physical vapor deposition process; calculating a scan rate of the substrate to achieve deposition of the material to a desired thickness in a single pass when deposited at the deposition rate; and performing the linear scan physical vapor deposition process while moving the substrate at the calculated scan rate.
