    Abstract: This semiconductor device has two leads (3) lying in the same axis, a prefabricated plastic can (1) which is filled with a plastic compound and has one of the leads passed through its bottom (1a), and a prefabricated die (4) attached between those sides of the inner ends (60, 70) of the leads (3) facing each other, the leads being inserted into, and having an offset within, the can. The manufacture of the leads starts with a wire (30) which unwinds from a spool (39), passes through a major part of the manufacturing stages unseparated, and is separated into the individual semiconductor devices only after the mounting of the cans (1).

  • Patent number: 5049526
    Abstract: A method for fabricating and especially for encapsulating a semiconductor device in a plastic package is disclosed. In accordance with one embodiment of the invention the method includes steps of providing an encapsulation mold having a first chamber and a second chamber, with the second chamber spaced outwardly from and substantially surrounding the first chamber. The first chamber is shaped to receive a removable insert. An insert is selected for the particular body type and style which is desired and that insert is secured in the first chamber. The insert has a cavity which is shaped to define the desired encapsulated device package body. A lead frame is provided including a bonding area and a plurality of leads, each lead having a inner portion near the bonding area and an outer portion extending outwardly from the bonding area.

  • Patent number: 5031028
    Abstract: A heat sink/electromagnetic shield assembly for a circuit element disposed upon a circuit board. A spring clip containing at least one hooked projection forming the spring is positioned in a confronting relationship with the circuit element. A U-shaped housing is slidingly positioned over the circuit element and the spring clip to enclose the circuit element and to compress the hooked projection which forms the spring. Compression of the hooked projection causes the hooked projection to exert a spring force to retain the housing in position about the circuit element. The assembly may be constructed in-line during construction of the electrical circuit disposed upon the circuit board.

  • Patent number: 5028987
    Abstract: A hermetic, high current package for a semiconductor device includes wide flat leads which are bonded to the contact pads of the device and formed to extend through apertures in an insulating lid. The lid is sealed to a base and the apertures around the leads are sealed with solder to provide the hermetic package. This package limits lateral current flow in the contact pads of the semiconductor device to relatively low levels which ensure the integrity of the contact pads.

  • Patent number: 5025305
    Abstract: A semiconductor device for detecting or emitting a magnetic line of force or light is so provided that the major surface of its built-in semiconductor chip has a predetermined inclination angle relative to a mount surface of a mount substrate. An active layer of element for detecting a magnetic line of force or light or an element for emitting a magnetic line of force or light is formed on the major surface of the semiconductor chip. It is, therefore, possible to achieve a smaller mount thickness as defined relative to a mount surface and to detect a magnetic line of force or light coming in a direction parallel to the mount surface or to emit a magnetic line of force or light in a direction vertical to the mount surface.

  • Patent number: 5019829
    Abstract: A TO-style plug-in package for MMICs and associated antenna structure is comprised of a microwave circuit component carrier having a generally cylindrically shaped conductive header upon which one or more MMICs are supported. An aperture through the header contains a conductor pin supported within a glass seal interface, so as to form a hermetically sealed matched impedance transmission line through the package. The conductor pin is connected to a bonding pad of a microwave circuit component on the header. A generally cylindrical conductive cover engages the header and encloses a cavity within which the microwave circuit components are supported. A microstrip antenna is supported on a dielectric layer overlying an outer surface of the conductive cover and is connected to a further conductor pin that extends through a glass-sealed aperture in the cover and forms a matched impedance transmission line from the antenna to the header.

  • Patent number: 4996170
    Abstract: An improved molding process utilizes a thixotropic compound. The thixotropic compound is transferred from a feed pot to a manifold having at least one outlet. The manifold is held at a temperature in which the thixotropic compound is not cured. The manifold is engaged with a mold that has an inlet opening that runs to a mold cavity, such that the outlet of the manifold and the inlet of the mold communicate with each other. The thixotropic compound is transferred from the manifold into the mold cavity, which is held at a temperature at which the thixotropic compound is cured. The manifold and the mold are then separated, drawing the thixotropic compound near the exit of the feed runners into the manifold, thus making a clean separation.
