Refurbishment of a coated chamber component
First Claim
1. A method of refurbishing a component of a process chamber, the component comprising a structure having an overlying coating comprising a first layer, the method comprising:
- (a) removing the first layer to form an exposed surface on the structure;
(b) during or after (a), cleaning the exposed surface with a cleaning fluid, thereby depositing cleaning residue on the exposed surface;
(c) heating the surface in a substantially non-oxidizing atmosphere to a temperature that is sufficiently high to vaporize the cleaning residue from the surface, thereby forming a cleaned surface; and
(d) forming a second layer over the cleaned surface.

Abstract
A component of a process chamber is cleaned and refurbished. The component has a structure with an overlying coating having of a first layer. To refurbish the component, the first layer is removed to form an exposed surface on the structure. During or after the removal of the coating, the exposed surface is cleaned with a cleaning fluid, which deposits cleaning residue on the exposed surface. The exposed surface is heated in a substantially non-oxidizing atmosphere to a temperature that is sufficiently high to vaporize the cleaning residue from the surface, thereby forming a cleaned surface. A second layer is formed over the cleaned surface.

12. A method of refurbishing a component of a process chamber, the component comprising a structure having an overlying coating comprising a first metal layer, the method comprising:
-
(a) removing the first metal layer to form an exposed surface on the structure;
(b) during or after (a), cleaning the exposed surface with a first cleaning fluid, thereby depositing first cleaning residue on the exposed surface;
(c) texturing the exposed surface by propelling blasting beads towards the surface;
(d) in a first baking step, heating the exposed surface in a substantially non-oxidizing environment to a temperature that is sufficiently high to vaporize first cleaning residue from the exposed surface, the substantially non-oxidizing atmosphere comprising less than about 1% by volume of oxygen gas;
(e) forming a second metal layer over the exposed surface, the second metal layer comprising a top surface;
(e) cleaning the top surface of the second metal layer with a second cleaning fluid, thereby depositing second cleaning residue on the top surface; and
(g) in a second baking step, heating the top surface of the second metal layer to a temperature that is sufficiently high to vaporize second cleaning residue from the top surface. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
