摘要:
In an LSI package, terminal resistance elements are formed of resistive paste which, consisting of a mixture of fine powder of either oxidized metal or carbon and fine powder of glass, is buried and sintered in a ceramic wiring board in the direction to penetrate it. Front side wiring, connecting the parts of the terminal resistance elements exposed on the front face of the ceramic wiring board to input/output circuits of the LSI chip to be mounted on the front face of the ceramic wiring board, is formed on the front face of the ceramic wiring board and in the top layer of the ceramic wiring board. Back side wiring, connecting the parts of the terminal resistance elements exposed on the back face of the ceramic wiring board to a voltage clamp wiring network, is formed on the back face of the ceramic wiring board.

On a ceramic substrate (122), spiral-type inductors (102 to 107) of a single layer wiring of a metal thin film are provided and respectively connected to a wiring pattern formed on another face of the substrate via through holes (114 to 119). A semiconductor chip (101) is flip-chip mounted on the substrate in a face-down manner. On the face of the semiconductor chip, capacitors composed of a highly dielectric material, resistors formed by an ion implantation method or a thin-film forming method, and FETs are provided, respectively. Interconnection between the substrate and an external circuit board is achieved employing terminals formed at end faces of the substrate. The terminals (108 to 113) have a concave shape with respect to the end face of the substrate. Thus, there is no need to use a package, and miniaturization and reduction in cost of a high-performance hybrid IC (100) is achieved.

摘要:
A method and resulting structure for constructing an IC package utilizing thin film technology. The package has a bottom conductive plate (10) that has a layer of ceramic vapor deposited onto the plate in a predetermined pattern. Adjacent to the insulative layer of ceramic is a layer of conductive metal (24) vapor deposited onto the ceramic. The layer of metal can be laid down onto the ceramic in a predetermined pattern to create a power plane, a plurality of signal lines, or a combination of power planes and signal lines. On top of the layer of conductive material is a lead frame (34) separated by a layer of insulative polyimide material. The polyimide material has a plurality of holes filled with a conductive material (38), which electrically couple the layer of conductive material with the leads of the lead frame. The power and ground pads of the integrated circuit are connected to the layer of vapor deposited conductive material and conductive plate, which are also coupled to the corresponding leads of the lead frame, thereby connecting the IC to the leads of the lead frame. The signal pads of the IC are connected to the lead frame and/or signal lines formed within the layer of vapor deposited conductive material. The IC and attached circuit package can then be encapsulated in a plastic shell.

Die in der kombinierten Schaltung (Figur 1) enthaltenen Varistoren (2, 3) sind nur noch Anteile des ursprünglich homogenen Körpers. Die übrigen Bereiche (23) des Substrat körpers (5) sind dadurch wenigstens nahezu elektrisch isolierend, weil sie zusätzlich wenigstens einen diese Eigen schaft bewirkenden Stoff (Lithiumoxid und/oder Man ganoxid) enthalten, der entweder nach dem Sintern des Sub stratkörpers (5) auf deisem oder vor dem Sintern auf dem Grünkörper aufgebracht worden ist und durch weiteren Erhitzungsprozeß (45, 45′) bei gegenbenenfalls gleich zeitigem Sintern (Variante 2) in den Körper eindiffundiert ist.

摘要:
L'invention concerne les semiconducteurs de type III-V et assimilés, qui travaillent à très hautes fréquences, jusque 100 GHz. De tels semiconducteurs sont encapsulés dans des boîtiers comprenant un cadre isolant (2), traversé par au moins une connexion d'entrée (5) et une connexion de sortie (6). Ces boitiers sont fermés par un couvercle isolant (3) fixé par soudure au moyen de deux métallisations (7, 8) sur le cadre et le couvercle. Un couplage existe entre les connexions (5, 6) par l'intermédiaire de condensateurs parasites (13, 14) formés par chaque connexion et le ruban de métallisation (7,8) à l'aplomb des connexions, ces condensateurs étant réunis par une ligne de propagation constituée par la soudure de fermeture du couvercle (3). Selon l'invention, le couvercle (3) est recouvert par une métallisation résistive (12), en contact avec la métallisation de soudure (8): la métallisation résistive et les condensateurs parasites constituent ainsi une ligne à pertes. Application à l'amélioration de l'isolement et des connexions d'entrées/sorties des semiconducteurs de puissance.
