Appl. No.:

11/622966

Inventors:

David M. Burtner - Belmont MA, US
Scott A. Townsend - Fort Collins CO, US
Daniel E. Siegfried - Fort Collins CO, US

Assignee:

Veeco Instruments, Inc. - Woodbury NY

International Classification:

H01J 7/24
H01J 49/10

US Classification:

250426, 250423 R, 250424, 31511141, 31511181, 3133621

Abstract:

A thermal control plate is easily removable and replaceable in an ion source. The ion source has a removable anode assembly, including the thermal control plate, that is separable and from a base assembly to allow for ease of servicing consumable components of the anode assembly. The thermal control plate may support a gas distributor and an anode in the anode assembly. The thermal control plate may have a port for passing working gas from one side of the thermal control plate to the other. An interface surface on the thermal control plate may have a pattern of recesses to allow the working gas to disperse underneath the gas distributor.

250423R, 250424, 250426, 31511141, 31511181, 3133621

Abstract:

An ion source has a removable anode assembly that is separable and from a base assembly to allow for ease of servicing the consumable components of the anode assembly. Such consumables may include a gas distributor, a thermal control plate, an anode, and one or more thermal transfer sheets interposed between other components. A pole piece and a cathode may also be part of the anode assembly. The anode assembly may be attached to the base assembly via the pole piece.

Abstract:

A gas distributor is easily removable and replaceable in an ion source. The ion source has a removable anode assembly, including the gas distributor, that is separable and from a base assembly to allow for ease of servicing consumable components of the anode assembly. The gas distributor may be mounted to a thermal control plate in the anode assembly with several set screws. The gas distributor may be disk-shaped with counterbores in a surface to recess the heads of the set screws. Alternately, the gas distributor may be clamped or held in place by other structures or components of the ion source.

Abstract:

One or more thermal transfer sheets are easily removable and replaceable in an ion source. The ion source has a removable anode assembly, including the thermal transfer sheets, that is separable and from a base assembly to allow for ease of servicing consumable components of the anode assembly. The thermal transfer sheets may be interposed between the consumable components within the anode assembly. The thermal transfer sheets may be thermally conductive and either electrically insulating or conductive.
