An assembly and a device for vapor deposition are provided in this disclosure, an assembly includes a cell and a housing, the cell is accommodated in the housing, the gaseous materials to be vapor deposited eject from the housing and are vapor deposited onto the substrate. The housing is capable of rotating relative to the cell. The film layer structure can be obtained by controlling the angles of rotation of the housing. Single film layer as well as the composite film layer with various changes of doping ratio can be formed on the substrate of the assembly and the device for vapor deposition in this disclosure.

Assembly and apparatus for vapor deposition

The present disclosure relates to an apparatus for detecting a distance between a carrier and a plate, the apparatus comprising: a base provided on the carrier; a rotation mechanism rotatably provided on the base and configured to rotate when the carrier is in contact with the plate during movement of the carrier relative to the plate; a rotation angle measuring mechanism configured to measure a rotation angle of the rotation mechanism so as to obtain the distance according to the rotation angle. The distance between the carrier and the plate can be calculated based on the rotation angle of the rotation mechanism, so that accurate measurement of the distance between the carrier and the plate can be realized. Further, the operation performance of the gap detection apparatus would not be affected or damaged by the vacuum environment.

Apparatus for detecting distance between carrier and plate
