DE500CL double electron gun co-evaporation coating system

DE500CL dual electron gun co-evaporation coating system is equipped with two electron beam evaporation sources, which can co-evaporate and deposit metal, semiconductor or dielectric materials on the substrate. It is an ideal platform for preparing lift-off process films and low-micro materials.



Open the door before the rubber ring of the evaporation cavity is sealed to facilitate the operation inside the cavity.

The opening of the substrate baffle is controlled by the film thickness meter closed loop.
