Abstract

A coating assembly for coating a plurality of substrates. The coating assembly includes a chamber. At least one target is disposed in the chamber and includes a coating material. At least one power supply is connected to the target. At least one support fixture is disposed in the chamber. The at least one support fixture includes a base having a plurality of recesses formed in an upper surface of the base. A first mounting component has a plurality of slots. The first mounting component is positioned on the upper surface of the base wherein at least some of the plurality of recesses are in registry with corresponding ones of the plurality of slots to define a plurality of cavities, each of the plurality of cavities configured to hold at least one of the plurality of substrates to be coated.

First claim

What is claimed is:

1. A coating assembly for coating a plurality of substrates, the coating assembly comprising:
a chamber;
at least one target disposed in the chamber and comprising a coating material;
at least one power supply connected to the target; and
at least one support fixture disposed in the chamber, the at least one support fixture comprising:
a base having a plurality of recesses formed in an upper surface of the base wherein at least one of the plurality of recesses opens to a surrounding environment at an outer peripheral edge of the base; and
a first mounting component having a plurality of slots,
the first mounting component positioned on the upper surface of the base wherein at least some of the plurality of recesses are in registry with corresponding ones of the plurality of slots to define a plurality of cavities, each of the plurality of cavities configured to hold at least one of the plurality of substrates to be coated.

2. The coating assembly according to claim 1 , wherein the base and the first mounting component are configured such that the plurality of substrates extends a predetermined distance above an upper surface of the first mounting component.

3. The coating assembly according to claim 1 , further comprising a second mounting component, the second mounting component positioned on the upper surface of the base and having an outer peripheral edge abutting an inner peripheral edge of the first mounting component to close an open end of at least one of the plurality of slots.

4. The coating assembly according to claim 3 , wherein at least one of the base, the first mounting component and the second mounting component is made from low-carbon steel.

5. The coating assembly according to claim 4 , wherein each of the base, the first mounting component and the second mounting component is made from low-carbon steel.

6. The coating assembly according to claim 3 , wherein at least one of the base, the first mounting component and the second mounting component is made from 12L14 low-carbon steel.

7. The coating assembly according to claim 6 , wherein each of the base, the first mounting component and the second mounting component is made from 12L14 low-carbon steel.

8. The coating assembly according to claim 1 , wherein the base is circular and the plurality of recesses extend radially about an outer periphery of the base.

9. The coating assembly according to claim 8 , wherein the first mounting component is a ring and open ends of the plurality of slots are in registry with an inner opening of the first mounting component.

10. The coating assembly according to claim 1 , wherein the at least one support fixture is attached to a rotatable shaft or a plurality of rotatable shafts is disposed in the chamber and each of the plurality of rotatable shafts includes at least one support fixture.

11. The coating assembly according to claim 1 , further comprising:
a shaft attached to a central opening of the at least one support fixture and a motor attached to the shaft for rotating the shaft and the at least one support fixture within the chamber about a longitudinal axis of the shaft, or
a plurality of rotatable shafts disposed in the chamber and each of the plurality of rotatable shafts including at least one support fixture that is rotatable about a longitudinal axis of a respective rotatable shaft.
