Abstract:
A method of controllably bonding a thin sheet to a carrier, wherein the thin sheet has a thin sheet bonding surface, and the carrier has a carrier bonding surface. Depositing a surface modification layer onto at least one of the thin sheet bonding surface and the carrier bonding surface so as to obtain a first surface energy on the one of the thin sheet bonding surface and the carrier bonding surface. Then, treating the surface modification layer so as to change the first surface energy to a second surface energy, wherein the second surface energy is greater than the first. And bonding the thin sheet bonding surface to the carrier bonding surface via the surface modification layer. Depositing the surface modification layer, and treating it, may be done by plasma polymerization processes.
Abstract:
Germanium-silicon oxide, germanium-silicon oxynitride and silica-germania-titania materials and oxynitride materials suitable for fabricating optical waveguides for liquid crystal based cross-connect optical switching devices have a refractive index of from about 1.48 to about 1.52 at 1550 nm, and a coefficient of thermal expansion at room temperature of from about 3 x 10{C to about 4.4 x 10{C. The compositions are adjusted so that the refractive index of the germanium-silicon oxide, germanium-silicon oxynitride or silica-germania-titania material is closely matched to the refractive index of a typical liquid crystal material whereby improved optical performance of a liquid crystal based cross-connect optical switching device is achieved. The coefficient of thermal expansion of the germanium-silicon oxide, germanium-silicon oxynitride, or silica-germania-titania material is closely matched to the coefficient of thermal expansion of silicon, whereby strain induced birefringence caused by thermal stresses is reduced or avoided.
Abstract:
Surface modification layers (30) and associated heat treatments, that may be provided on a sheet (20), a carrier (10), or both, to control both room-temperature van der Waals (and/or hydrogen) bonding and high temperature covalent bonding between the thin sheet and carrier. The room-temperature bonding is controlled so as to be sufficient to hold the thin sheet and carrier together during vacuum processing, wet processing, and/or ultrasonic cleaning processing, for example. And at the same time, the high temperature covalent bonding is controlled so as to prevent a permanent bond between the thin sheet and carrier during high temperature processing, as well as maintain a sufficient bond to prevent delamination during high temperature processing.

Abstract:
A substrate (310) includes an opaque chrome coating (320) on a surface of the substrate (310) dry-etched to form an aperture (340), wherein chrome in the aperture is below detectable limit. A method of forming an opaque chrome coating (320) on a substrate (310) includes depositing an initial thickness of the opaque chrome coating on the substrate without ion-assist or with undetectable ion-assist and depositing the remainder of the opaque chrome coating with or without ion-assist. In one embodiment the invention is directed to an apertured optical element (300) having a substrate transmissive to light (310) and an opaque chrome coating (320) on the substrate defining an aperture (340). Three and four layer opaque coatings of various materials are disclosed, including three layer chrome/chrome oxide/chrome coatings.
Abstract:
Described herein are articles and methods of making articles, for example glass articles, comprising a thin sheet and a carrier, wherein the thin sheet and carrier are bonded together using a modification (coating) layer, for example an aromatic polymer coating layer, and associated deposition methods and inert gas treatments that may be applied on the thin sheet, the carrier, or both, to control van der Waals, hydrogen and covalent bonding between the thin sheet and the carrier. The modification layer bonds the thin sheet and carrier together with sufficient bond strength to prevent delamination of the thin sheet and the carrier during high temperature processing while preventing a permanent bond during high temperature processing.
