Abstract
The application discloses a magnetic control deformation self-cleaning mechanism and a thin film deposition device thereof. The magnetic control deformation self-cleaning mechanism comprises a telescopic pipe, an alternating magnetic field generating module and a ferromagnetic shape memory alloy piece. The ferromagnetic shape memory alloy piece is attached to the inner wall of the lumen of the telescopic pipe. The alternating magnetic field generating module generates an alternating magnetic field to produce a magnetic force on the ferromagnetic shape memory alloy piece, so that the ferromagnetic shape memory alloy piece is deformed due to phase change, and the particles deposited on the surface of the ferromagnetic shape memory alloy piece are removed. The magnetic control deformation self-cleaning mechanism does not need to frequently replace the bellows, reduces the use cost, can obviously reduce the process particle adhesion, can more thoroughly perform internal air extraction and purging, and finally improves the process quality and efficiency.
