    Abstract: A glass substrate with modified surface regions is disclosed. The glass substrate includes a first side and an opposite second side, an alkali-containing bulk disposed between the first and second sides, and a first alkali-depleted region formed in the alkali-containing bulk on the first side. The first alkali-depleted region defines at least a portion of a first topographical feature. The first topographic feature includes a height that extends in a first direction from a base portion of the first topographical feature to an outermost portion of the first topographical feature. The first direction is oriented parallel to a thickness of the glass substrate between the first and second sides. The first topographic feature also includes a width that extends in a second direction between at least two, spaced apart wall portions of the first topographical feature. The second direction is oriented normal to the first direction.

    Abstract: Embodiments of a glass substrate including an alkali-containing bulk and an alkali-depleted surface layer, including a substantially homogenous composition with at least 51 mol % Al2O3 are disclosed. In some embodiments, the alkali-depleted surface layer includes about 0.5 atomic % alkali or less. The alkali-depleted surface layer can be substantially free of hydrogen and/or crystallites. Methods for forming a glass substrate with a modified surface layer are also provided.

    Abstract: A glass or glass-ceramic carrier substrate, the substrate having undergone at least one complete cycle of a semiconductor fabrication process and having also undergone a reclamation process following the end of the semiconductor fabrication process; the glass or glass-ceramic carrier substrate comprising at least one of the following properties: (i) a coefficient of thermal expansion of less than 13 ppm/° C.; (ii) a Young's Modulus of 70 GPa to 150 GPa; (iii) an IR transmission of greater than 80% at a wavelength of 1064 nm; (iv) a UV transmission of greater than 20% at a wavelength of 255 nm to 360 nm; (v) a thickness tolerance within the same range as the thickness tolerance of the carrier substrate before undergoing at least one complete cycle of the semiconductor fabrication process; (vi) a total thickness variation of less than 2.5 μm; (vii) a failure strength of greater than 80 MPa using a 4-point-bending test; (viii) a pre-shape of 50 μm to 300 μm.
