Abstract
A method for forming a low temperature cofired ceramic (LTCC) device includes forming a channel in a first LTCC tape layer. A wax is inserted in the channel. The wax is of a type that burns out at a temperature below a sintering temperature of the first LTCC tape layer. At least a second LTCC tape layer is stacked on the first LTCC tape layer to form a stack. The stack is pressed sufficiently for the first and second layers to bond into a laminate. The laminate is fired at the sintering temperature to form a sintered ceramic structure from the first and second LTCC tape layers, so that all or substantially all of the wax is burned out from the channel.
