1. A method for strengthening glass sheets having conductive traces formed thereon, comprising:
- positioning a first glass sheet having a first set of conductive traces formed thereon and a second glass sheet having a second set of conductive traces formed thereon such that a side of the first glass sheet having the first set of conductive traces faces a side of the second glass sheet having the second set of conductive traces;
adhering the first glass sheet to the second glass sheet to protect the first and second sets of conductive traces; and
applying a strengthening treatment to an untreated region of at least one of the first glass sheet and the second glass sheet.

Abstract
Methods and apparatus for protecting the thin films during chemical and/or thermal edge strengthening treatment. In one embodiment, a portion of each individual sheet is laminated. Pairs of sheets are then sealed together such that the thin film sides face inward to form a thin film sandwich. In some embodiments, the sandwich in then immersed in a chemical strengthener. In other embodiments, a localized treatment is applied to the unstrengthened edges.

18. A method for strengthening an edge, the method comprising:
-
applying a first treatment to a main sheet; applying a film process to the main sheet; forming a first sheet and a second sheet from the main sheet; positioning a sensitive surface of the first sheet so as to face a sensitive surface of the second sheet; sealing the first sheet and the second sheet, thus forming sealed sheets; and applying a second treatment to the sealed sheets. - View Dependent Claims (19, 20, 21, 22)

23. An apparatus comprising:
-
a substrate having a first surface and a second surface, the second surface created by the separation of the substrate from a larger sheet; one or more conductive traces formed on the first surface of the substrate prior to the separation of the substrate from the larger sheet; and a substance applied to the second surface of the substrate, the substance adapted to strengthen the second surface. - View Dependent Claims (24, 25, 26)
