Facilitated processing for controlling bonding between sheet and carrier
First Claim
1. A method of forming an article, comprising:
- obtaining a glass sheet having a glass-sheet bonding surface with a perimeter;
obtaining a glass carrier having a carrier bonding surface with a perimeter;
coating at least one of the glass sheet and carrier bonding surfaces with a surface modification layer;
connecting the glass sheet with the carrier via the surface modification layer;
removing, from the perimeter of the glass sheet and the carrier while connected, a portion of the surface modification layer so as to expose a portion of the bonding surface on each of the glass sheet and the carrier, wherein the exposed portion of the glass-sheet bonding surface adjoins the exposed portion of the carrier bonding surface; and
heating, after the removing and the exposing, the glass sheet and carrier at a temperature ≧
400°
C. but less than the strain point of both the glass of the glass sheet and the glass of the carrier so as to bond the perimeter of the glass sheet bonding surface with the perimeter of the carrier bonding surface.

Abstract
A method of forming an article from a glass sheet (20) having a glass-sheet bonding surface (24) and a glass carrier (10) having a carrier bonding surface (14). At least one of the glass sheet and carrier bonding surfaces is coated with a surface modification layer (30), and then the glass sheet is connected with the carrier via the surface modification layer. From the perimeter of the glass sheet and the carrier while connected, there is removed a portion of the surface modification layer so as to expose a portion (19, 29) of the bonding surface on each of the glass sheet and the carrier. The glass sheet and carrier are then heated at a temperature ≧400° C. so as to bond the perimeter of the glass sheet (26) with the perimeter of the carrier (16).
