A glass or glass-ceramic plate is provided that has two side faces, a thickness of between 2 mm and 6 mm, a circumferential edge face, a flatness less than or equal to 0.1%, and a region of a first face having a mean surface roughness of less than 0.5 m and a standard deviation of the surface roughness of less than 0.1 m. The mean surface roughness and the standard deviation are determined by measuring a roughness at nine points on the first face by measuring a line profile with a stylus device and with evaluation according to ISO 4827. The nine points are at least 5 cm apart from one another. The plate further includes a coating on two subregions of the region that are at least 3 cm apart from one another, where the coating has a raggedness in the subregions that differ by not more than 10%.

A glass article having a dimpled glass bump formed integrally thereon by laser-irradiation methods. The glass bump includes a lower region connected to an upper region by an inflection region. The lower region projects from a surface of the glass article and is defined by concavely rounded sides with a radius of curvature R1. The upper region includes a transition portion and a top surface. The transition portion is defined by convexly rounded sides with a radius of curvature R2. The transition portion connects to the lower portion via the inflection region. The upper portion connects to the transition portion and is defined by a concavely rounded top portion between convexly rounded top portions.

A method for producing a glass article having high hydrolytic resistance is provided. A glass tube consisting of borosilicate glass and having an Al.sub.2O.sub.3 content of less than 1 weight-%, a ZrO.sub.2 content of 2-12 weight-%, and a glass transition temperature T.sub.g is reshaped into a glass article and is subsequently subjected to a thermal post-treatment. To reduce the alkali release of the glass article, the glass article is subjected to a treatment temperature of T.sub.BT.sub.g+5 K over a treatment time of t.sub.B5 min and is subsequently cooled during the thermal post-treatment.

A glass composite for use in Extreme Ultra-Violet Lithography (EUVL) is provided. The glass composite includes a first silica-titania glass section. The glass composite further includes a second doped silica-titania glass section mechanically bonded to a surface of the first silica-titania glass section, wherein the second doped silica-titania glass section has a thickness of greater than about 1.0 inch.
