A method is disclosed for scribing a contained crack or vent in a chemically strengthened glass sheet. The glass has shallow surface regions under compressive stress, bounding a central region under tensile stress. The vent is formed by rapidly bulk-heating the glass, using radiation from a carbon monoxide laser, to a depth just below a surface compressive region and extending marginally into the tensile stress region then rapidly cooling the heated region with a water mist spray. The glass sheet can be subsequently divided along the vent by application of mechanical or thermal stress.

Laser-scribing of chemically strengthened glass

An electrode structure wherein galvanic corrosion at adhesion layers formed between electrodes and electronic or electro-optic substrates is eliminated. The electrode structure includes an electro-optic crystalline substrate, an amorphous layer disposed on the crystalline substrate, the amorphous layer having a composition substantially similar to a composition of the crystalline substrate, and a gold layer disposed directly on the amorphous layer. The amorphous layer is created using ion sputtering etching techniques that clean and activate the surface of the crystalline substrate such that the gold layer is able to adhere to it.
