Abstract

The invention discloses a magnetron sputtering source and magnetron sputtering equipment with the magnetron sputtering source. The magnetron sputtering source comprises a target material, a magnetron located above the target material, and a scanning mechanism which is connected to the magnetron and is used for controlling the magnetron to move above the target material. The scanning mechanism comprises a driver, a driving shaft, a driving gear, a connection rod, a driven shaft, a driven gear, a cam, a guide rail, a roller and an elastic component. Through adjustment of a distance between the driving shaft and the driven shaft, when the magnetron moves around the cam, a scanning speed of the magnetron at the periphery and the center of the target material is adjusted so that the etching depth of the outer ring of the target material is increased and particles produced in film deposition are reduced and film uniformity and a target material utilization rate are improved. The magnetron sputtering source has the advantages of stable structure, smooth transmission, simple operation and good practicality.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a magnetron source and a magnetron sputtering device with the magnetron source.
