Abstract: Electrical devices having tunable capacitance are provided. The tunable capacitance is achieved by placing an appropriate material between substrate layers and by controllably applying a pressure to the material to compress the material or alter the shape of a well in which the material is contained, and thereby alter the capacitance of the electrical device. The composition, shape and dimension of the embedded materials determine how the capacitance of the electrical device is altered upon compression of the embedded material in response to an applied control signal. Generally, as the embedded material is compressed, the material will become more dense and the capacitance of the integrated electrical device is altered.

Abstract: Electrical devices having tunable electrical characteristics are provided, such as variable resistors, capacitors and inductors. The tunable electrical characteristics are achieved by placing an appropriate material between substrate layers and by controllably applying a pressure to the material to compress the material or alter the shape of a well in which the material is contained, and thereby alter the electrical characteristics of the electrical device. The composition, shape and dimension of the embedded materials determine how the electrical characteristics of the electrical device are altered upon compression of the embedded material in response to an applied control signal.

Abstract: A method of making a packaged electrical device comprises the steps of (a) connecting one end of a wire to a first point (e.g., a first electrical node) in the package, and (b) connecting the other end of the wire to a second point (e.g., a second electrical node) in the package, characterized by (c) causing energy from an external source to heat at least one predetermined segment of the wire to a temperature that is below its melting point (MP) but not below its recrystallization temperature (RCT), and (d) cooling the heated segment to a temperature below its RCT [e.g., to room temperature (RT)], thereby to increase the stiffness modulus of the segment. In one embodiment, the external source is a laser whose optical output is absorbed by the segment. In another embodiment, the heated segment is rapidly cooled (i.e., quenched) to RT.

Abstract: An integrated circuit comprises at least one circuit element having at least one bond site and a passivation layer. The bond site is accessible through an aperture in the passivation layer. At least two ball bumps are disposed at the bond site. A first ball bump is bonded to the bond site, and each additional ball bump is bonded on a previously bonded ball bump so that the height of the ball bumps is greater than the thickness of the passivation layer above the bond site. A ball bond is bonded to an uppermost ball bump and has a wire formed integrally therewith.

Abstract: A process for fabricating a power hybrid module including placing at least one carrier assembly in at least one opening in at least one printed circuit board, mounting the at least one carrier assembly and the at least one printed circuit board on assembly tape, electrically connecting one of the at least one carrier assemblies and one of the at least one printed circuit boards, overmolding the at least one carrier assembly and the at least one printed circuit board and removing the assembly tape to produce a surface mount power hybrid module. A power hybrid module including at least one printed circuit board with at least one opening therein, at least one carrier assembly, positioned in the at least one opening such that said at least one carrier assembly may be surface mounted and electrically connected to the at least one printed circuit board, and an overmold over the at least one printed circuit board and the at least one carrier assembly.
