Abstract
Provided is a glass substrate having low charging properties. The glass substrate is characterized by comprising, in terms of mass %, from 1.7% to less than 9% of B2O3, not more than 0.01% of Li2O, 0.001-0.03% of Na2O, 0.0001-0.007% of K2O, 0.0011-0.035% of Na2O+K2O and more than 0% to 0.4% of SnO2 as glass composition.
Claims20
A glass substrate comprising:
- a plurality of through-glass vias extending through the glass substrate, adjacent through-glass vias being separated by a minimum average distance DM;
- and
- a chemically strengthened region with a depth of layer such that the depth of layer extends from a surface of the glass substrate to a distance within a bulk of the glass substrate, the chemically strengthened region having a higher compressive stress than a remainder of the glass substrate,
- wherein the depth of layer of the chemically strengthened region is about 30% or less of the distance DM.
