Abstract

Analyzing the influence of the magnetic field on magnetron sputtering process

the principles of the magnetic field design for the working region of the rectangular planar DC magnetron sputtering apparatus are summarized

and two feasible magnet configurations are proposed. The magnetic field distribution of one apparatus is evaluated by finite element method to well coincide with the measurements. Simultaneously

the influence of the magnetic field distribution on the target erosion is investigated

and detailed measures for improving the magnetic field are proposed. The magnetic field is improved by shimming method with the shunt bar

and the horizontal magnetic field component with saddle distribution enables to enhance the target utilization. The inclined pole shoe has little benefit to the magnetic field. In addition

staggering the joint gap between the magnets and precisely magnetizing the permanent magnet facilitate enhancing the uniformity of the magnetic field in the working region.
