Abstract

A carrier apparatus includes an article including a first major surface, a second major surface, a thickness between the first major surface and the second major surface, and an outer edge extending across the thickness between the first major surface and the second major surface. The carrier apparatus includes a coating including a central portion disposed on the first major surface of the article and an outer exposed portion disposed on the outer edge of the article, and a gasket including a first surface contacting the coating. An outer interface between the first surface of the gasket and the coating defines an outer boundary isolating the central portion of the coating from the outer exposed portion of the coating. Methods of processing a carrier apparatus to remove at least a portion of the coating from the article are also provided.

First claim

What is claimed is:

1. A method of processing a carrier apparatus comprising:
an article comprising a first major surface, a second major surface, a thickness between the first major surface and the second major surface, and an outer edge extending across the thickness between the first major surface and the second major surface;
a coating comprising a central portion disposed on the first major surface of the article and an outer exposed portion disposed on the outer edge of the article; and
a gasket comprising a first surface contacting the coating, an outer interface between the first surface of the gasket and the coating defines an outer boundary isolating the central portion of the coating from the outer exposed portion of the coating, the method comprising:
exposing the outer exposed portion of the coating to an etchant,
wherein exposing the outer exposed portion of the coating to the etchant comprises submerging the outer exposed portion of the coating into a bath comprising the etchant.

2. The method of claim 1 , exposing the outer exposed portion of the coating to the etchant removes the outer exposed portion of the coating from the article.

3. The method of claim 2 , after removing the outer exposed portion of the coating from the article, the coating is disposed entirely on the first major surface of the article.

4. The method of claim 1 , the carrier apparatus further comprising a base comprising a support surface, a second surface of the gasket contacting the support surface of the base, and the method further comprising applying a force to the article in a direction toward the support surface of the base, thereby pressing the gasket between the support surface of the base and the coating.

5. The method of claim 4 , exposing the outer exposed portion of the coating to the etchant is performed while applying the force to the article.

6. A method of processing a carrier apparatus comprising:
an article comprising a first major surface, a second major surface, a thickness between the first major surface and the second major surface, and an outer edge extending across the thickness between the first major surface and the second major surface;
a coating comprising a central portion disposed on the first major surface of the article and an outer exposed portion disposed on the outer edge of the article; and
a gasket comprising a first surface contacting the coating, an outer interface between the first surface of the gasket and the coating defines an outer boundary isolating the central portion of the coating from the outer exposed portion of the coating,
wherein the article further comprises:
an aperture defined between a first opening in the first major surface of the article and a second opening in the second major surface of the article, an inner edge of the article extending across the thickness between the first opening and the second opening, the coating comprising an inner exposed portion disposed on the inner edge of the article, and an inner interface between the first surface of the gasket and the coating defines an inner boundary isolating the central portion of the coating from the inner exposed portion of the coating, and
further wherein the method comprises:
exposing the outer exposed portion of the coating and the inner exposed portion of the coating to an etchant.

7. The method of claim 6 , exposing the outer exposed portion of the coating and the inner exposed portion of the coating to the etchant comprises submerging the outer exposed portion of the coating and the inner exposed portion of the coating into a bath comprising the etchant.

8. The method of claim 6 , exposing the outer exposed portion of the coating and the inner exposed portion of the coating to the etchant removes the outer exposed portion of the coating and the inner exposed portion of the coating from the article.

9. The method of claim 8 , after removing the outer exposed portion of the coating and the inner exposed portion of the coating from the article, the coating is disposed entirely on the first major surface of the article.

10. The method of claim 6 , wherein the carrier apparatus further comprises:
a base comprising a support surface, a second surface of the gasket contacting the support surface of the base, and the method further comprising applying a force to the article in a direction toward the support surface of the base, thereby pressing the gasket between the support surface of the base and the coating.

11. The method of claim 10 , exposing the outer exposed portion of the coating and the inner exposed portion of the coating to the etchant is performed while applying the force to the article.

12. A method of processing a carrier apparatus comprising:
an article comprising a first major surface, a second major surface, a thickness between the first major surface and the second major surface, and an outer edge extending across the thickness between the first major surface and the second major surface;
a coating comprising a central portion disposed on the first major surface of the article and an outer exposed portion disposed on the outer edge of the article; and
a plurality of gaskets, a first gasket of the plurality of gaskets comprising a first surface contacting the coating, a first outer interface between the first surface of the first gasket and the coating defines a first outer boundary isolating the central portion of the coating from the outer exposed portion of the coating, and a second gasket of the plurality of gaskets comprising a second surface contacting the second major surface of the article, a second outer interface between the second surface of the second gasket and the second major surface of the article defines a second outer boundary isolating a central portion of the second major surface of the article from an outer exposed portion of the second major surface of the article, wherein the first outer boundary laterally circumscribes the second outer boundary, the method comprising:
exposing the outer exposed portion of the coating to an etchant,
wherein exposing the outer exposed portion of the coating to the etchant comprises submerging the outer exposed portion of the coating into a bath comprising the etchant.

13. The method of claim 12 , exposing the outer exposed portion of the coating to the etchant removes the outer exposed portion of the coating from the article.

14. The method of claim 13 , after removing the outer exposed portion of the coating from the article, the coating is disposed entirely on the first major surface of the article.

15. The method of claim 12 , wherein the carrier apparatus further comprises:
a first base comprising a support surface facing the first major surface of the article, a second base comprising a support surface facing the second major surface of the article, the article, the coating, the first gasket, and the second gasket are positioned between the support surface of the first base and the support surface of the second base.

16. The method of claim 15 , comprising applying at least one of a first force to the first base in a direction toward the support surface of the second base and a second force to the second base in a direction toward the support surface of the first base, thereby pressing the first surface of the first gasket against the coating and the second surface of the second gasket against the second major surface of the article.

17. The method of claim 16 , exposing the outer exposed portion of the coating to the etchant is performed while applying the at least one of the first forc
