Abstract
A process for making multiple microelectronic ceramic substrates uses an interface layer between stacked layers of green sheets that are laminated with the interface layer, then fired to produce the ceramic substrates. The interface layer acts to protect the substrates, and to hold them together before firing, then thermally degrades at a desired point in the firing cycle to separate the individual substrates. The invention also includes the ceramic substrates produced by the method.
