Each multilayer module of a plurality of multilayer modules has a plurality of layers wherein each layer has a substrate therein. The plurality of multilayer modules includes a first multilayer module including a first layer and a second multilayer module including a second layer each having a top side and bottom side. The first layer and second layer each includes a substrate, at least one electronic element, and a plurality of electrically-conductive traces. The plurality of multilayer modules further includes a heat-separating layer disposed between the top side of the first layer and the bottom side of the second layer. The first multilayer module is adhered to the second multilayer module and the first multilayer module can be detached from the second multilayer module by applying heat to the heat-separating layer.

A method and structure are disclosed which involve the re-wafering of previously processed and tested IC chips. The chips are encapsulated in supporting non-conductive material in a neo-wafer, so that they may be further processed preparatory to dicing layer units from the neo-wafer, which layer units are ready for stacking in a three-dimensional electronic package. Although the layer areas are the same, different stacked layers may contain different sized IC chips, and a single layer may encapsulate a plurality of chips. Precision of location of the separate IC chips in the neo-wafer is insured by use of photo-patterning means to locate openings in the neo-wafer into which extend conductive bumps on the chips. The neo-wafer is preferably formed with separate cavities in which the chips are located before they are covered with the encapsulating material.

The stacks (140, 160) are preferably mated to one another in a transverse fashion in order to achieve a natural full-mesh connection. Also contemplated are the use of superconducting IC switching circuits (142) and a suitable superconducting cooling housing (730), as permitted by the compact nature of the multi-stage switching network (100), in order to operate at high speed and low power.

摘要:
A method is disclosed for providing electrical connections to electronic elements within a multilayer module. The method includes providing first and second active layers having first and second edges, respectively. Each active layer includes a flexible, polymer substrate and at least one electronic element formed within the substrate. Electrically-conductive traces provide electrical connections from the first and second edges to the electronic elements. An adhesive is applied to at least one of a top surface of the first active layer and a bottom surface of the second active layer and the top surface of the first active layer is adhered to the bottom surface of the second active layer. The first edge and the second edge are aligned with each other thereby forming a side of the multilayer module. Electrically-conductive lines are applied along the side of the multilayer module to provide electrical connections to the traces.

A system and method are disclosed for producing electro-optic components with transparent, ferroelectric PLZT (perovskite) film characteristics, without lead diffusion. In particular, the fabrication of PLZT-on-sapphire electro-optic components for devices such as spatial light modulators, integrated infrared detectors, and optoelectronic integrated circuits is disclosed, permitting integration of such devices with semiconductor devices having the same substrate, such as silicon-on-sapphire circuits. The system comprises a PLZT film deposition apparatus, a silicon dioxide deposition apparatus, an annealing apparatus, and an optional plasma etching apparatus. During film deposition, material from a PLZT target (source) of suitable (9/65/35) composition is deposited on the substrate and is epitaxially grown on the R-plane (1102) of the substrate, forming a non-ferroelectric, pyrochloric film. The substrate and film are then placed in a silicon dioxide (SiO.sub.2) deposition chamber where SiO.sub.2 is deposited as an insulating layer covering (capping) the film. The substrate, with film and SiO.sub.2 layer, is then placed in an annealing apparatus, at a selected temperature above 550.degree. C. for a selected period of time, to transform the non-ferroelectric, pyrochloric film into a ferroelectric, perovskite film of (9/65/35) composition. The SiO.sub.2 layer may then be removed by conventional etching.
