Abstract

Implementations described herein relate to apparatus for post exposure processing. More specifically, implementations described herein relate to field-guided post exposure process chambers and cool down/development chambers used on process platforms. In one implementation, a plurality of post exposure process chamber and cool/down development chamber pairs are positioned on a process platform in a stacked arrangement and utilize a shared plumbing module. In another implementation, a plurality of post exposure process chamber and cool down/development chambers are positioned on a process platform in a linear arrangement and each of the chambers utilize an individually dedicated plumbing module.

First claim

What is claimed is:

1. A platform apparatus, comprising:
a factory interface;
a plumbing module; and
a process module disposed between the factory interface and the plumbing module, wherein the process module comprises:
a central region having a robot disposed therein; and
a plurality of process stations disposed about the central region, wherein each process station includes a process chamber and a post process chamber in a stacked arrangement, wherein the process chamber comprises:
a chamber body defining a process volume, wherein a major axis of the process volume is oriented vertically and a minor axis of the process volume is oriented horizontally;
a moveable door coupled to the chamber body;
a first electrode coupled to the door, the first electrode configured to support a substrate thereon;
a second electrode coupled to the chamber body, the second electrode at least partially defining the process volume;
a first plurality of fluid ports formed in a sidewall of the chamber body adjacent the process volume; and
a second plurality of fluid ports formed in the sidewall of the chamber body adjacent the process volume opposite the first plurality of fluid ports.

2. The apparatus of claim 1 , wherein the plumbing module is shared among the plurality of process stations.

3. The apparatus of claim 1 , wherein ingress/egress openings of the process chamber and the post process chamber are disposed adjacent to and face the central region.

4. The apparatus of claim 1 , wherein the process chamber is disposed on top of the post process chamber in each of the process stations.

5. The apparatus of claim 1 , wherein the post process chamber is disposed on top of the process chamber in each of the process stations.

6. The apparatus of claim 1 , further comprising:
a backing plate disposed between the first electrode and the door.

7. The apparatus of claim 1 , further comprising:
a process fluid source in fluid communication with the process volume via a first plurality of channels and the first plurality of fluid ports.

8. The apparatus of claim 7 , further comprising:
a fluid outlet in fluid communication with the process volume via a second plurality of channels and the second plurality of fluid ports.

9. The apparatus of claim 1 , wherein the first electrode is configured to vacuum chuck a substrate thereon.

10. The apparatus of claim 9 , wherein a vacuum source is in fluid communication with the first electrode.

11. The apparatus of claim 1 , wherein the chamber body is formed from polytetrafluoroethylene.

12. The apparatus of claim 1 , wherein the post process chamber comprises:
a chamber body defining a process volume;
a rotatable pedestal disposed within the process volume;
a fluid delivery arm configured to deliver cleaning fluid to the process volume; and
a shield capable of being raised and lowered by a motor, the shield having an inner diameter greater than a diameter of the rotatable pedestal, wherein the shield is disposed radially outward of the rotatable pedestal.

13. A platform apparatus, comprising:
a factory interface;
a plumbing module; and
a process module disposed between the factory interface and the plumbing module, wherein the process module comprises:
a central region having a robot disposed therein, the robot comprising a plurality of end effectors, the end effectors moveable in three axes; and
a plurality of process stations disposed about the central region, wherein each process station includes a process chamber and a post process chamber in a stacked arrangement, wherein the post process chamber comprises:
a chamber body defining a process volume;
a rotatable pedestal disposed within the process volume;
a fluid delivery arm configured to deliver cleaning fluid to the process volume; and
a shield capable of being raised and lowered by a motor, the shield having an inner diameter greater than a diameter of the rotatable pedestal, wherein the shield is disposed radially outward of the rotatable pedestal.

14. The apparatus of claim 13 , wherein the process chamber comprises:
a chamber body defining a process volume, wherein a major axis of the process volume is oriented vertically and a minor axis of the process volume is oriented horizontally;
a moveable door coupled to the chamber body;
a first electrode coupled to the door, the first electrode configured to support a substrate thereon;
a second electrode coupled to the chamber body, the second electrode at least partially defining the process volume;
a first plurality of fluid ports formed in a sidewall of the chamber body adjacent the process volume; and
a second plurality of fluid ports formed in the sidewall of the chamber body adjacent the process volume opposite the first plurality of fluid ports.
