Abstract
A sublimation device includes a first heater and a second heater. The first heater includes a proximal end, a distal end, and an inner surface. The distal end is disposed opposite the proximal end. The inner surface extends between the proximal end and the distal end and at least partially forms a cavity. The second heater is disposed proximate the distal end of the first heater.
Claims20
A sublimation device comprising:
- a first heater including a proximal end, a distal end disposed opposite the proximal end, and an inner surface extending between the proximal end and the distal end, the inner surface at least partially forming a cavity;
- and
- a second heater disposed proximate the distal end of the first heater and configured to support a workpiece thereon, wherein:
- the first heater is configured to move, relative to the second heater, between an open orientation and a closed orientation;
- the first heater includes two or more distinct heat zones configured to provide different temperatures to correspondingly-zoned regions of an outer side surface of the workpiece;
- and
- wherein an upper opening is defined at the proximal end of the first heater, and the upper opening is configured to remain open during a sublimation process performed on the workpiece.

A sublimation device comprising:
- a first heater having a tube-shaped structure at least partially defining a cylindrical cavity, wherein the cylindrical cavity comprises a central axis, wherein a lower end of the tube-shaped structure defines a lower opening and an upper end of the tube-shaped structure, opposite the lower end, defines an upper opening;
- and
- a second heater disposed proximate the lower end of the first heater, the second heater comprising an upper surface that is perpendicular to the central axis and that is configured to support a workpiece thereon, wherein:
- the upper surface of the second heater defines a lower surface of the cylindrical cavity such that the second heater defines a closed bottom of the cylindrical cavity;
- and
- the upper opening of the tube-shaped structure of the first heater is configured to remain open during a sublimation process performed on the workpiece.

A sublimation device comprising:
- a heating assembly having a tube-shaped structure at least partially defining a cylindrical cavity that comprises a central axis, wherein a lower end of the tube-shaped structure defines a lower opening and an upper end of the tube-shaped structure defines an upper opening, and wherein the tube-shaped structure of the heating assembly comprises an insulative insert, the insulative insert comprising:
- a sidewall portion extending concentrically around the central axis of the cylindrical cavity;
- and
- an upper lip portion extending radially outward from the sidewall portion at the upper end of the tube-shaped structure;
- and
- a spring sheet disposed radially outward and concentrically around the sidewall portion of the insulative insert.
