Abstract: Multilayer green tape stacks having sufficient layers so that the fired stack is at least 2 millimeters in thickness on a metal support substrate are made by interleaving two types of green tapes comprising a low dielectric loss glass of a first type including at least 5% of an oxide filler and a green tape of a second type comprising a low dielectric loss glass and a higher amount of an oxide filler than the green tape of the first type, on a metal support substrate. These fired green tape stacks shrink on firing only in the thickness dimension.

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.

Abstract: A package for an electronic component includes a metal base plate and a body of an insulating material, such as glass or ceramic, on and bonded to a surface of the base plate. The body is formed of a plurality of layers of the insulating material stacked and bonded to each other and has at least one opening extending therethrough to the base plate. Strips of a conductive material, such as a metal, are on the surface of various layers of the body. An electronic component is mounted in the opening in the body and has terminals which are electrically connected to the conductive strips on the body, preferably by wires. Vias of a conductive material may extend through some of the layers of the body to connect the conductive strips to terminals on the surface of the body. A cover plate of an insulating material may extend over the body and the opening therein to enclose the electronic component in the body.

Abstract: An electroluminescent display formed on a ceramic substrate having a front ceramic surface and a back ceramic surface. The ceramic substrate includes a metal core that provides structural support, electrical ground, and heat dissipation. Electroluminescent cells are mounted on the front ceramic surface and driver circuits for driving the of electroluminescent cells are mounted on the back ceramic surface. The driver circuits are positioned directly behind said electroluminescent cells. Connectors extend through said ceramic substrate and the electroluminescent cells to different driver circuits. By positioning the driver circuits close to the EL cells, the drive lines from the drivers to the EL cells are short which allows for high refresh rates and low resistance losses. Each of the driver circuits can drive one electroluminescent cell or a group of electroluminescent cells. EL display cells coupled to a cermet electrode can also be driven by a field emission device or a low power electron beam.
