Cylindrical magnetron target and spindle apparatus
A cylindrical magnetron target and spindle attachment apparatus for affixing a cylindrical magnetron target to a rotatable support spindle. The attachment apparatus includes a target and a spindle. The target defines a receiving portion. The spindle has a spindle plug. The spindle plug is disposed within the receiving portion of the target. The attachment apparatus increases the speed and ease of removing and installing cylindrical rotating targets onto a support spindle.
1. An apparatus for affixing a cylindrical magnetron target to a rotatable support spindle, comprising:
a cylindrical target structure having a receiver in a hollow portion of a target structure interior; and
a support spindle structure having a spindle plug at one end thereof, the spindle plug being operatively configured to be entirely disposed within the receiver.
2. The apparatus of claim 1 , wherein:
the receiver comprises a head aperture for receiving a head of a fastener; and
the spindle plug comprises a thread aperture for receiving a thread of a fastener.
3. The apparatus of claim 2 , wherein the head aperture comprises a socket portion for receiving a socket head of a fastener.
4. The apparatus of claim 2 , wherein the head aperture comprises a flat portion for receiving a flat head of a fastener.
5. The apparatus of claim 2 , wherein the spindle plug comprises an O-ring groove operatively configured to hold an O-ring seal disposed between an inner surface of the target structure interior and the spindle plug.
6. The apparatus of claim 1 , wherein the cylindrical target structure comprises a target.
7. A sputtering magnetron attachment apparatus comprising:
a cylindrical target structure having a receiver in a hollow portion of a target structure interior, the receiver comprising a head aperture for receiving a head of a fastener; and
a support spindle structure having a spindle plug at one end thereof disposed within the receiver, the spindle plug comprising a thread aperture for receiving a thread of a fastener; and
a fastener disposed within the head aperture and the thread aperture such that the support spindle structure is operatively coupled to the cylindrical target structure.
8. The apparatus of claim 7 , wherein the fastener comprises a socket head fastener and the head aperture comprises a socket portion for receiving a socket head of the fastener whereby the support spindle structure is flexibly coupled to the cylindrical target structure.
9. The apparatus of claim 7 , wherein the fastener comprises a flat head fastener and the head aperture comprises a flat portion for receiving a flat head of the fastener whereby the support spindle structure is securely coupled to the cylindrical target structure.
10. The apparatus of claim 7 , wherein the spindle plug comprises an O-ring groove operatively configured to hold an O-ring seal disposed between an inner surface of the target structure interior and the spindle plug.
11. The apparatus of claim 7 , wherein the cylindrical target structure comprises a target.
12. A method for affixing a cylindrical magnetron target to a rotatable support spindle, the method comprising:
providing a cylindrical target structure having a receiver in a hollow portion of a target structure interior; and
providing a support spindle structure having a spindle plug at one end thereof; and
inserting the spindle plug entirely within the receiver such that the support spindle structure can be connected to the cylindulcal target structure.
13. The method of claim 12 , wherein the provided receiver comprises a head aperture for receiving a head of a fastener and the provided spindle plug comprises a thread aperture for receiving a thread of a fastener, the method further comprising steps of:
providing a fastener;
turning the spindle structure relative to the target structure to align the head aperture with the thread aperture; and
installing the fastener through the head aperture into the thread aperture to couple the spindle structure to the target structure.
14. The method of claim 13 , wherein the providing a fastener step comprises providing a socket head fastener whereby the spindle structure is flexibly coupled to the target structure.
15. The method of claim 13 , wherein the providing a fastener step comprises providing a flat head fastener whereby the spindle structure is securely coupled to the target structure.
16. The method of claim 12 , wherein the provided spindle plug comprises an O-ring groove, the method further comprising steps of:
providing an O-ring seal; and
placing the O-ring seal into the O-ring groove such that the O-ring seal is disposed between an inner surface of the target structure interior and the spindle plug.
