Abstract
Patterned laminated green tape multilayer stacks can be fired while maintaining the dimensions of the pattern by applying, as by screen printing or spraying, a ceramic ink over surface portions of the green tape stack. Complex patterns can be formed in the green tapes by punching openings in one or more of the laminated green tape stacks before laminating them together.
