Abstract:
A semiconductor package contains a cover with a flange around that portion of the edge in contact with the bottom of the package. The flange makes an acute angle with the package bottom. Bonding material placed between the flange and the package bottom, when melted, is drawn by capillary action along facing surfaces of the flange and package bottom thereby to form a solid bond between the cover and the bottom.
Abstract:
The thermal cycling capability of a high-current semiconductor device is significantly increased by disposed a tungsten strain buffer in compression between a terminal of the device housing and an external pressure applying thrust member.
Abstract:
A temperature transmitter includes a temperature probe, such as an RTD or thermocouple, and a transmitter housing. Electrical circuitry in the transmitter housing is adapted for coupling to the temperature probe and providing an output related to a sensed temperature. The temperature housing has a first side for coupling to the temperature probe and a second side which carried a plurality of electrical connections electrically connected to the circuitry carried in the transmitter housing. An elongated recess on an outer surface of the first side of the transmitter housing channels electrical wiring which connects to the temperature probe in a direction away from the temperature probe and toward the electrical connections carried on the second side of the transmitter housing.
Abstract:
Described is an improved common faced terminated multi-layer ceramic capacitor structure capable of embodying multiple capacitors of various maximum voltage and capacitance rating and method for its making. The structure features a ceramic body including multiple sections having a dielectric element and companion plate of one or more types, the types defined by the number and placement on the plate of plate tabs. The sections are aligned in the body such that the plates are located at displaced intervals in the direction of the body length while the plate tabs are located at displaced intervals in the direction of the body width and exposed at a common body face. Buses interconnect the tabs and plate in groups at common face. By selectively connecting the buses, one or more capacitors may be formed in the body. A structure is improved by providing grooves in the common face to align tabs in groups and to maintain the groups separated with the effect that the maximum voltage the structure can withstand is not reduced to mis-alignment of tabs during formation of the body. The method features steps for grooving the common face and simultaneously aligning tabs in the body.
Abstract:
A semiconductor apparatus comprising a first and a second electrode substrate arranged substantially in parallel to each other, a semiconductor element containing a plurality of electrode members located between and opposite to the first and second electrode substrates, a layer of organic adhesive material inserted between the first and second electrode substrates for their integral bonding, and a means for connecting the first and second electrode substrates with the aforesaid plurality of electrode members mechanically as well as electrically.
Abstract:
MIXED SILICON OXIDE-SILICON NITRIDE FILMS OF PARTICULAR COMPOSITIONS ARE VAPOR DEPOSITED CONTROLLABLY ON SEMICONDUCTOR DEVICES BY A REACTION PROCESS IN NITROGEN AT BETWEEN 700-900*C. USING SILANE (SIH4) AND NITRIC OXIDE (NO) AS THE REACTANTS. THE COMPOSITION OF THE DEPOSITED FILM IS A FUNCTION OF THE RATIO OF REACTANT CONCENTRATIONS. PARTICULAR COMPOSITIONS YIELD FILMS WHICH COMBINE MINIMAL STRESS, RESISTANCE TO PENETRATION OF CONTAMINANTS, AND ETCHABILITY.
Abstract:
A HIGH FREQUENCY TRANSISTOR IS DESCRIBED HAVING INPUT, OUTPUT AND COMMON LEADS. IN ORDER TO REDUCE THE UNDESIRED FEEDBACK EFFECT OF A STRAY SERIES INDUCTANCE IN THE COMMON LEAD, THE OUTPUT LEADS ARE ARRANGED SO AS TO CROSS ONE ANOTHER IN SUCH CLOSE PROXIMITY AS TO INDUCTIVE-
LY COUPLE THEM TOGETHER PROVIDING A FEEDBACK OPPOSITE TO THAT OF THE STRAY INDUCTANCE IN ORDER TO COMPENSATE THE LATTER.
