摘要： A vacuum evaporation apparatus comprises a housing, in which a main vacuum cavity, a side vacuum cavity and a switch assembly are disposed. The main vacuum cavity is configured for vacuum evaporation. A tomography detection module for scanning a crucible to be measured and a manipulator for accessing a crucible in main vacuum cavity are disposed in the side vacuum cavity. A switch assembly is disposed between the main vacuum cavity and the side vacuum cavity. Where the switch assembly is opened, the main vacuum cavity and the side vacuum cavity are communicated with each other to enable accessing the crucible. Where the switch assembly is closed, the main vacuum cavity and the side vacuum cavity are separated from each other.

摘要： The present disclosure provides a phase shifter and a manufacturing method thereof, and an antenna. The phase shifter includes a first substrate including a reference electrode, and a second substrate including a delay line and a bias line. An orthographic projection of the bias line on the first substrate and that of the delay line, at least partially overlap with that of the reference electrode respectively. The orthographic projection of the bias line on the first substrate does not overlap with that of the delay line. The delay line is used for transmitting a microwave signal and defining a microwave transmission region. When electrical signals are applied to the reference electrode, the delay line and the bias line, electric field areas formed respectively between the reference electrode and the delay line, and between the reference electrode and the bias line, cover the microwave transmission region.
