摘要： Power semiconductor device structures and assemblies with improved heat dissipation characteristics and low impedance interconnections include a thermally-conductive dielectric layer, such as diamondlike carbon (DLC) overlying at least portions of the active major surface of a semiconductor chip, with vias formed in the dielectric layer in alignment with contact pads on the active major surface. A patterned metallization layer is formed over the thermally-conductive dielectric layer, with portions of the metallization layer extending through the vias into electrical contact with the chip contact pads. A metal structure is electrically and thermally coupled to selected areas of the patterned metallization, such as by solder bonding or by a eutectic bonding process. In different embodiments, the metal structure may comprise a metal conductor bonded to the opposite major surface of another power semiconductor device structure, a heat-dissipating device-mounting structure, or simply a low-impedance lead.

摘要： An inductor uses high temperature superconductors in order to obtain high Q for high frequency operation. The superconductors are applied as thin films to substrates. In some embodiments, superconductor thin films are applied to opposite sides of the same substrate. Superconductive thin films are applied outside the magnetic field establishing superconductive thin films in order to shield against leakage of the magnetic field beyond the inductor. The inductor is connected to a capacitor to realize a resonant circuit used in a power conversion system.

摘要： A multi-cellular power field effect semiconductor device includes a high conductivity layer of metal or a metal silicide disposed in intimate contact with the source region of the device. This high conductivity layer is self-aligned with respect to the aperture in the gate electrode through which the source region is diffused. The presence of this high conductivity layer allows a substantially smaller contact window to be employed for making contact between the final metallization and the source region. As a consequence, the aperture in the gate electrode and the cell size of the device can both be substantially reduced. The device has substantially improved operating characteristics. A method of producing the device is also described.

摘要： A magnetic or electromagnetic circuit component includes an embedded magnetic material (e.g., ferromagnetic) in an HDI structure with alternating dielectric and metal or winding layers. In one embodiment, the ferromagnetic material is situated in a substrate well, or cavity, with or without an adhesive. Alternatively, the ferromagnetic material is co-fired with the ceramic substrate and then machined to achieve a required core shape. An electroplating process is employed to construct the metal layers, such process including differential plating for varying the thickness of metal layers and/or other portions of the circuit. Laser ablation or any other suitable technique is employed to make through-holes for insertion of the posts of a ferromagnetic core plate used to complete a magnetic circuit, if required. Advantageously, a magnetic or electromagnetic component may have a height of less than about 0.1 inch. Furthermore, such magnetic or electromagnetic circuit components allow for very low inductance interconnections between these components and other circuit elements. Moreover, in a power supply, for example, not only can the complete power supply be built using HDI technology, but power density is increased at relatively low cost and at a high level of reproducibility.

摘要： A voltage-doubler rectifier includes an ac fullbridge diode rectifier and a dc-to-dc converter having two output boost circuits. One of the output boost circuits is coupled between the rectifier and a dc link, and the other output boost circuit is coupled, with opposite polarity, between the rectifier and the circuit common. Two series-connected filter capacitors are also coupled between the dc link and the circuit common. In a preferred embodiment, the two output boost circuits each comprise either a series, parallel, or combination series/parallel resonant circuit and a rectifier. A switch is coupled between the junction joining one pair of diodes of the rectifier and the junction joining the two filter capacitors. For a relatively high ac line voltage, the switch is open, and the circuit operates in a low boost mode. For a relatively low ac line voltage, the switch is closed, and the circuit operates in a high boost, or voltage-doubling, mode.

摘要： A synchronous rectifier is able to operate at higher frequencies and provides an output having lower noise than prior art FET synchronous rectifier system by using field effect switching devices which contain only one conductivity type of semiconductor material and connecting a high speed, low charge storage diode in parallel. Schottky diodes are preferred whereby there is no junction diode in the structure. Conventional FETs may be used when paralleled with a Schottky diode which prevents the FET's parasitic internal diode from becoming conductive.

摘要： A high frequency, high density, low profile magnetic circuit component includes a magnetic core having a first magnetic layer and a second magnetic layer with a conductive layer deposited therebetween, each magnetic layer being a multilayer structure comprised of alternating magnetic and insulating films. The magnetic films are anisotropic and are driven along their magnetic hard axis in order to reduce excess eddy current losses. To reduce fringing field eddy current losses, a distributed air gap is structured in the magnetic layers. The magnetic core has a distributed air gap formed therein in order to minimize eddy current losses in the conductive layer. The conductive layer has a conductive material patterned on a insulating substrate and is situated between the first and second magnetic layers such that the conductive material extends beyond the peripheries of the first and second magnetic layers, thereby maximizing the amount of magnetic material that is driven in the hard axis.
