Method of forming a glass-ceramic structure.

摘要

Enhanced planarity and dimensional integrity of sintered glass-ceramic structures containing multi-level (e.g. copper) conductor patterns is obtained by a two stage firing of the structure, first between the anneal and softening points of the crystallizable glass particles in the structure, interrupting the firing, superimposing a lightweight platen on the structure, and heating through the coalescing temperature to the crystallization temperature of the glass.
