Disassembly tool for electrostatic chuck
The present disclosure relates to a tool for disassembling an electrostatic chuck assembly and, more particularly, to a tool for separating an electrostatic chuck and isolator and methods of use. The tool includes: a cradle having a sidewall; a pressing frame having legs which are positionable adjacent to the sidewall of the cradle and an upper connecting member connecting to each of the legs, the upper connecting member being positionable over a top of the cradle and having at least one opening; and at least one mechanism extending through the at least one opening of the pressing frame, the at least one mechanism being moveable to exert a downward pressure on an electrostatic chuck suspended within the cradle.
1. A tool, comprising:
a cradle comprising a sidewall;
a pressing frame having legs which are positionable adjacent to the sidewall of the cradle, an upper connecting member connecting to each of the legs, and a lower connecting member extending from the legs, the lower connecting member being positionable at a bottom of the cradle and the upper connecting member being positionable over a top of the cradle and having at least one opening; and
at least one mechanism extending through the at least one opening of the pressing frame, the at least one mechanism being moveable to exert a downward pressure on an electrostatic chuck suspended within the cradle.
2. The tool of claim 1 , wherein the at least one mechanism is a set of screws, the at least one opening is two threaded openings and the set of screws are threaded into the two threaded openings.
3. The tool of claim 2 , wherein each screw of the set of screws includes a downward extending push pin which engages a respective pin or threaded mechanism attached to the electrostatic chuck suspended within the cradle.
4. The tool of claim 1 , wherein the cradle includes a channel.
5. The tool of claim 4 , wherein the channel is at the bottom of the cradle.
6. The tool of claim 5 , wherein the lower connecting member is insertable into the channel at the bottom of the cradle.
7. The tool of claim 6 , wherein the lower connecting member does not extend into an opening of the cradle.
8. The tool of claim 1 , wherein the sidewall of the cradle is dimensioned and structured to hold an isolator thereon and to suspend the electrostatic chuck within an opening of the cradle.
9. The tool of claim 8 , wherein the at least one opening of the pressing frame is alignable with openings of the isolator.
10. A tool, comprising:
a cradle comprising a sidewall dimensioned and structured to hold an isolator thereon and to suspend an electrostatic chuck within an opening;
a pressing frame having two vertical legs, an upper connecting member connecting to each of the vertical legs, and a lower connecting member connecting at a lower end of the vertical legs and which is insertable at the bottom of the cradle, the two vertical legs being positionable adjacent to the sidewall of the cradle and the upper connecting member having at least one threaded opening positioned over the cradle; and
at least one screw threaded to the at least one threaded opening of the pressing frame, the at least one screw being moveable to exert a downward pressure on the electrostatic chuck suspended within the cradle and held to the electrostatic chuck by a static force.
11. The tool of claim 10 , wherein the at least one screw is two screws and the at least one threaded opening is two threaded openings, and each screw includes a downward extending push pin which engages a respective pin or threaded mechanism attached to the electrostatic chuck suspended within the cradle.
12. The tool of claim 10 , wherein the cradle includes a channel at a bottom of the cradle and the lower connecting member is insertable into the channel at the bottom of the cradle.
13. The tool of claim 12 , wherein the lower connecting member does not extend into the opening of the cradle.
14. The tool of claim 12 , further comprising temporary screws which extend through openings of the isolator and which are temporarily attach to the electrostatic chuck.
15. The tool of claim 14 , wherein the at least one threaded opening of the pressing frame is alignable with the openings of the isolator.
16. A tool, comprising:
a cradle comprising a sidewall, a bottom and a channel at the bottom;
a pressing frame comprising:
two vertical legs;
an upper connecting member connecting to each of the vertical legs at a first end;
a lower connecting member connecting to each of the vertical legs at a second end and which is insertable into the channel;
at least one threaded opening in the upper connecting member; and
at least one screw threaded to the at least one threaded opening; and
a push pin at an end of the at least one screw, the push pin exerts a downward pressure on an electrostatic chuck when the at least one screw is turned.
17. The tool of claim 16 , wherein the at least one screw is two screws, the at least one threaded opening is two threaded openings.
18. The tool of claim 16 , wherein the lower connecting member is insertable into the channel and does not extend into the opening of the cradle.
19. The tool of claim 16 , wherein the sidewall of the cradle has a circumference which is sized to hold an isolator thereon and to suspend the electrostatic chuck within an opening.
20. The tool of claim 19 , further comprising temporary screws which extend through openings of the isolator and which are temporarily attach to the electrostatic chuck.
