Abstract
A composite ceramic substrate for receiving an ejection head chip for a micro-fluid ejection head and a method for making the composite ceramic substrate. The substrate includes a high temperature previously fired ceramic base having a substantially planarized first surface and at least one fluid supply slot therethrough. A low temperature co-fired ceramic (LTCC) tape layer bundle having at least two LTCC tape layers is attached to the ceramic base at an interface between the LTCC tape layer bundle and the first surface of the ceramic base. The LTTC tape layer bundle has at least one chip pocket therein and at least one of the LTCC tape layers includes a plurality of conductors.
