Abstract: Carriers for microelectronics fabrication may include a strengthened substrate formed from glass or glass-ceramic having an average thickness greater than 1.0 mm and less than or equal to 2.0 mm. The strengthened glass substrate may have a single-side surface area greater than or equal to 70,000 mm2. The substrate may also have a compressive stress greater than or equal to 200 MPa and a depth of layer from about 50 μm to about 150 μm. The substrate may further include a tensile stress region having a stored elastic energy of less than 40 kJ/m2 providing for a flat fragmentation factor of less than or equal to 5.

Abstract: A flexible substrate are disclosed comprising an amorphous inorganic composition, wherein the substrate has a thickness of less than about 250 μm and has at least one of: a) a brittleness ratio less than about 9.5 (μm)−1/2, or b) a fracture toughness of at least about 0.75 MPa·(m)1/2. Electronic devices comprising such flexible devices are also disclosed. Also disclosed is a method for making a flexible substrate comprising selecting an amorphous inorganic material capable of forming a substrate having a thickness of less than about 250 μm and having at least one of: a) a brittleness ratio of less than about 9.5 (μm)−1/2, or b) a fracture toughness of at least about 0.75 MPa·(m)1/2; and then forming a substrate from the selected inorganic material.

Abstract: A method of making a strengthened glass article includes providing a flat glass article having a select contour and a glass surface covered by a protective coating layer. The protective coating layer is removed from the glass surface without touching the glass surface with any solid object. Immediately after the protective coating layer is removed from the glass surface, the flat glass article is subjected to an ion-exchange process to strengthen the flat glass article and improve the resistance of the flat glass article to subsequent damage.
