    摘要: Thermoelectric devices having enhanced thermal characteristics are fabricated using multilayer ceramic (MLC) technology methods. Aluminum nitride faceplates with embedded electrical connections provide the electrical series configuration for alternating dissimilar semiconducting materials. Embedded electrical connections are formed by vias and lines in the faceplate. A portion of the dissimilar materials are then melted within the tunnels to form a bond. Thermal conductivity of the faceplate is enhanced by adding electrically isolated vias to one surface, filled with high thermal conductivity metal paste. A low thermal conductivity material is also introduced between the two high thermal conductivity material faceplates. Alternating semiconducting materials are introduced within the varying thermal conductivity layers by punching vias within greensheets of predetermined thermal conductivity and filling with n-type and p-type paste or may also be patterned in linear or radial fanout patterns through screening techniques and lamination of wire structures. a liquid channel within the faceplate is used to enhance thermal energy transfer. Thermoelectric devices are physically incorporated within the IC package using MLC technology.

    摘要: Method for producing ceramic laminates from a plurality of greensheet layers which include one or more thin greensheet layers, e.g. having a thickness less than about 3 mils, with interposed patterned circuit layers and conductive vias, while avoiding the loss of strength and the distortion encountered when paste compositions are pre-applied to such thin greensheet layers. The invention avoids the aforementioned problems by the use of a plurality of greensheet layers including thicker, paste-resistant greensheet layers having a thickness greater than the thin greensheet layer, e.g., between 5 and 10 mils, each pair of the thicker greensheet layers confining therebetween an unscreened thin greensheet layer, one of the thicker greensheet layers also being screened with the circuit pattern layer normally applied to the interposed thin greensheet layer. Thereafter the superposed layers are laminated and sintered to form the composite.
