Abstract: A method for performing a location search includes receiving a location search query, identifying one or more geographic feature documents that satisfy the location search query, ranking the identified geographic feature documents in accordance with scores that are based, at least in part, on corresponding address support scores, to produce a set of ranked documents, and providing results, in accordance with the ranked documents, that identify at least one geographic feature corresponding to at least one of the ranked documents. An address support score for an identified geographic feature document can be based on one or more of: a standalone support score and a template support score.

Abstract: An LTCC (low temperature cofired ceramic) structure which has conductors to which leads are to be bonded for connection to external circuitry. The conductors include additives to promote adhesion to the ceramic layer. The presence of these additives degrade bonding performance. For better bondability of the leads, a pure conductor metal layer, devoid of the additives is placed on the conductors in areas where leads are to be bonded. This pure conductor metal layer may be cofired with the stack of ceramic layers or may be post fired after stack firing.

Abstract: A method of forming an LTCC structure having at least one open cavity on each of first and second opposing sides is disclosed that includes the steps of forming a first LTCC structure including a first side having a plurality of cavities and a second side, subjecting the first LTCC structure to a first pressure, forming a second LTCC structure including a first side having a plurality of cavities and a second side, subjecting the second LTCC structure to a second pressure, arranging the first LTCC structure and the second LTCC structure such that the first LTCC structure second side faces the second LTCC structure second side, and subjecting the placed-together first and second LTCC structures to a third pressure to join the first LTCC structure to the second LTCC structure. A product formed by the subject method is also disclosed.

Abstract: An LTCC module includes a base on one or more surfaces for receiving one or more external components to be attached to the module. A base is formed of a plurality of layers of metallization in a predetermined pattern. The layers include an adhesion layer on the LTCC module surface, with one or more intermediate layers, followed by a top layer. The module is fired with each application of the layers at a reduced temperature lower than the normal cofiring temperature of the LTCC module, but of sufficient value to partially sinter the layers. After the last applied top layer, the module is fired once at an elevated temperature to fully sinter the layers.

Abstract: A cavity pattern for a laminated structure such as a substrate for integrated circuitry is formed in a sheet of unfired low temperature cofired ceramic (LTCC) material also known as "green" tape. One sheet at a time is placed in a flexible ram forming die including a resilient rubber pressure pad and a template including the pattern to be formed in the sheet. A pair of outer pressure plates hold the pressure pad and template in place. When a sheet of unfired LTCC material is placed between the pressure pad and template and pressurization is applied to the outer plates, extrusion of the rubber material through the template causes the tape to be sheared off at the edges of the holes in the template, thus effectively cutting the required pattern in the sheet. Following pressurization, the sheet now with the pattern cut therein is removed from the die and the residual tape cut-outs are subsequently removed from the template by a vacuum.

Abstract: A thick film metallization compatible with low temperature cofired ceramics (LTCC) that displays very low microwave insertion losses commensurate with those of thin film gold. However, the disclosed metallization is applied similar to conventional metallizations by screen printing and has no limit to the number of layers achievable. The electrical performance of the metallization is attained by using a spherical metal particle shape and uniform particle size distribution in the thick film paste. The advantage of this invention is that superior microwave performance can be achieved in electronic packages without the cost and limitations imposed by thin film metallization techniques.
