Title: Semiconductor device with linear silicone resin on intermediate insulation - giving level surface, ensuring constant dia. of etched through-holes
Inventor: FUJIKI NORIAKI
IPC: H01L23/532
Filed: 1993-05-14
Abstract: Semiconductor devices have (A) a semiconductor substrate (1) or (B) a semiconductor substrate (1) with p- and n-type surfaces, a p-type channel transistor on the p-type surface and an n-channel transistor on the n-type surface, the 2 transistors being connected with one another. In both cases, the substrate is coated in the given sequence with a first cpd. layer (9) with first and second cpd. zones (90a,90b), an intermediate insulating film (10), a film (14) of a linear silicone resin of formula (I) with through-holes (10a,10b) to the cpd. zones (90a,90b), and a second cpd. layer (12) connected with the cpd. zones (90a,90b) through these holes; and R1 = phenyl or lower alkyl; R2 = H or lower alkyl; n = 20-1000. USE/ADVANTAGE - Devices with a reliable multilayer cpd. structure can be produced, esp. with numerous through-holes of constant dia., since the (I) film makes the surface of the insulating layer planar. In an example, a CMOS inverter formed by 2 MOS transistors, formed on one surface of a p-type Si substrate by p- and n-type trough diffusion layers (2,3) with n- and p-source and drain zones (4b,5b,4a,5b) and gate electrode wires (6b,6a) over gate oxide films. These transistors are insulated from one another by a field oxide film (7). A first insulating film is formed and the drain of the n-channel transistor is connected to the source (4b) of the p-channel transistor by an Al cpd. layer (9) through a contact hole, then a second insulating film (10) is formed. This is covered with a (I) film and through-holes (10a,10b) are formed through this and the second insulating film down to the first Al cpd. layer. A second Al cpd. film is formed and covered with a passivating film. The through-holes (10a,10b) are of the same dia.

Abstract: A coupling element is described for the connection of two microline strip supports each having at least one microstrip line, which is intended for use with radio frequencies and is in each case routed on a dielectric film (1) which is continuously metallised on the underneath. The coupling element comprises two carrier boards (4, 6), one of which, as a base board (4), forms a continuously metallised surface (5) and the other is a covering board (6) which is made of a dielectric material and is fitted with at least one thin conductor track (7), the film (1) being arranged, with the microstrip lines (2, 2') which are to be connected, in a push fit between these carrier boards in such a manner that the metallised surface (5) of the base board (4) rests on the metallised underneath (3) of the film (1), and the conductor track (7) of the covering board (6) rests on the end sections of the microstrip lines (2, 2') which are to be connected. Normally, a plurality of microstrip lines (2, 2') are in this case routed parallel to one another, and the covering board (6) is fitted with the same number of conductor tracks (7), arranged in the same manner as on the microstrip line carrier. This coupling element makes it possible to connect detachably microstrip lines, in a simple manner, the connection matching the planar structure of the microstrip lines and avoiding transmission losses and reflections resulting from a local change in the characteristic impedance. The conductor tracks (7) on the covering board (6) ... Original abstract incomplete. <IMAGE>

Title: Pre=pressure valve for hydraulic clutch
Inventor: WINKELMANN LUDWIG
IPC: F16L37/40
Filed: 1994-05-27
Abstract: The valve has a housing-integrated sealing seat (23) which compresses a piston (15) and axially adjoining seal (18) carried on the ring piston (8) on the housing (3) so the seal lip (27) packs on to the piston. The ring piston and seal are moved to form the vent gap (33) on the seat, the ring piston re-setting from the filled system. An additional diaphragm seal on the seat also moves to form the gap, the seal guided in a stepped bore (7) sealed by the lip. Both pistons (8,15) have dissimilarly sized recesses on their faces (24,25) or are offset. The seat is thus opened by independent axial movement of the ring piston and the seal. When not engaged, the piston is spring-loaded centrally on to the housing endstop as led through a seal bore leaving an annular gap (26) for flow transfer. The sealing seat can be forcibly opened by a closing flap set in the line connection and equipped with cylindrical pins for the axial movement of the ring piston and the seal (18).
