发明名称 Substrate manufacturing method
摘要 A substrate manufacturing method includes steps of preparing a bonded substrate stack formed by bonding a second substrate to a first substrate having an insulator at least on a surface, forming a gettering layer to capture a metal contamination on the surface of the bonded substrate stack to form a composite substrate stack, annealing the composite substrate stack, and removing the gettering layer from the composite substrate stack.
