Abstract:
A method of controllably bonding a thin sheet having a thin sheet bonding surface with a carrier having a carrier bonding surface, by depositing a carbonaceous surface modification layer onto at least one of the thin sheet bonding surface and the carrier bonding surface, incorporating polar groups with the surface modification layer, and then bonding the thin sheet bonding surface to the carrier bonding surface via the surface modification layer. The surface modification layer may include a bulk carbonaceous layer having a first polar group concentration and a surface layer having a second polar group concentration, wherein the second polar group concentration is higher than the first polar group concentration. The surface modification layer deposition and the treatment thereof may be performed by plasma polymerization techniques.
Abstract:
Described herein are articles and methods of making articles, including a first sheet and a second sheet, wherein the thin sheet and carrier are bonded together using a coating layer, preferably a hydrocarbon polymer coating layer, and associated deposition methods and inert gas treatments that may be applied on either sheet, or both, to control van der Waals, hydrogen and covalent bonding between the sheets. The coating layer bonds the sheets together to prevent formation of a permanent bond at high temperature processing while at the same time maintaining a sufficient bond to prevent delamination during high temperature processing.
Abstract:
A GRINSCH laser having an asymmetric configuration wherein the optical confinement is weighted more to the n-doped multilayer section than to the p-doped multilayer section. The GRINSCH laser can emit laser light at a wavelength λ=976 nm over a broad area with a beam power of 11.4 W at a 12 A bias current at a temperature of 20° C. Fabry-Perot and distributed Bragg reflector GRINSCH laser configurations are disclosed.
Abstract:
A method includes depositing a surface modification layer on sidewalls of a plurality of cavities of a shaped article. The surface modification layer is formed from a glass material including a mobile component. The shaped article is formed from a glass material, a glass ceramic material, or a combination thereof. At least a portion of the mobile component is migrated from the surface modification layer into surface regions of the sidewalls of the shaped article, whereby subsequent to the migration, the surface regions have a reduced annealing point compared to a bulk of the shaped article. The surface modification layer and the surface regions of the sidewalls are reflowed. A surface roughness of the surface modification layer disposed on the sidewalls following the reflowing is less than a surface roughness of the sidewalls prior to the depositing.
Abstract:
Methods of forming vias in substrates having at least one damage region extending from a first surface etching the at least one damage region of the substrate to form a via in the substrate, wherein the via extends through the thickness T of the substrate while the first surface of the substrate is masked. The mask is removed from the first surface of the substrate after etching and upon removal of the mask the first surface of the substrate has a surface roughness (Rq) of about less than 1.0 nm.
