Patent ID: 8500978

Claim:
A composite coating apparatus, comprising: a main body defining a first and a second chambers with a separating board intervening therebetween, the separating board defining a coating opening intercommunicating the first and second chambers; an evaporation source received in the first chamber and facing the coating opening and a sputter target; the sputter target received in the second chamber and facing the coating opening and the evaporation source; two carrying boards received within one of the first and second chambers and rotatably connected to the separating board, the carrying boards being positioned around the coating opening, each carrying board defining a receiving groove for holding a substrate; and two actuators configured for driving the carrying boards to rotate between a first coating position and a second coating position, respectively; wherein when a specific one of the carrying boards is at the first coating position, a surface of the substrate held by the specific carrying board faces and aligns with the coating opening; and wherein when the specific carrying board is at the second coating position, the surface of the substrate held by the specific carrying board faces away from the separating board; wherein each actuator comprises a connecting board and a first motor, each connecting board is connected to the separating board and extends two shaft plates upward from a surface thereof, each shaft plate defines a shaft hole, each carrying board extends a shaft at an end thereof distant from the receiving groove thereof, each of the carrying boards is received between the shaft plates of the respective actuator, the shaft of each of the carrying boards extends into the shaft holes of the connecting board of the respective actuator and is coupled to the first motor of the respective actuator, and each first motor is configured for driving the respective carrying board to rotate about the shaft between the first coating position and the second coating position.
