Abstract:
An object of this invention is a method for producing circuit boards having electronic, optical and functional features, wherein the surface of the base plate (1) of the circuit board is provided with metallization (7, 8), an insulating protective layer upon the metallization, the next conductive layer (9, 10) upon the protective layer, etc., until the needed number of layers has been deposited one upon the other. The base plate (1) is produced of a plate preform, the handling of which in the production of a circuit board is performed from the processing location in the middle of the plate preform, such as a hole (2).
Abstract:
A method of manufacturing a patterned electric circuit. The method comprises the steps of providing a cold gas-dynamic spraying (CGDS) device, providing a substrate, and depositing a pattern of electrically conductive material with the CGDS device on the substrate by relative movement between the CGDS device to the substrate.
Abstract:
A multilayer circuit substrate for multi-chip modules or hybrid circuits includes a dielectric base substrate, conductors formed on the base substrate and a vacuum deposited dielectric thin film formed over the conductors and the base substrate. The vacuum deposited dielectric thin film is patterned using sacrificial structures formed by shadow mask techniques. Substrates formed in this manner enable significant increases in interconnect density and significant reduction of over-all substrate thickness.
Abstract:
The invention relates to a method for producing a substrate (1) comprising a conductor assembly (4, 41, 42) that is suitable for use at high frequencies, said substrate having improved high-frequency characteristics. The method comprises the following steps: deposition of a structured glass layer (9, 91, 92, 93, 13) comprising at least one opening (8) above a contact region (71 - 74) by vapour deposition on the substrate (1); and application of at least one conductor structure (100, 111, 112, 113) to the glass layer (9, 91 - 93), which is in electric contact with the contact region (71 - 74).
Abstract:
A multilayer substrate device formed from a base substrate (12) and alternating metalization layers (14) and dielectric layers (16). Each layer is formed without firing. Vias (44) may extend through one of the dielectric layers (16) such that two metalization layers (14) surrounding the dielectric layers (16) make contact with each other. The vias (44) may be formed by placing pillars (40) on top of a metalization layer (14), forming a dielectric layer (16) on top of the metalization layer (14) and surrounding the pillars (40), and removing the pillars (40). Dielectric layers (16) may be followed by other dielectric layers (16) and metalization layers (14) may be followed by other metalization layers (14).

Abstract:
Bei dem Verfahren zum Erzeugen einer Leiterbahn (10) wird diese auf einem Trägerbauteil (4) durch ein strahlgebundenes thermisch-kinetisches Auftragsverfahren direkt aufgetragen, ohne dass das Trägerbauteil (4) vorbehandelt werden muss. Dadurch ist ein sehr flexibles und kostengünstiges Herstellen eines Formbauteils (2A-2F) mit einem integriertem Leiterbahnmuster möglich. Insbesondere im Kraftfahrzeug-Bereich können spezielle Kundenwünsche zeitnah und problemlos durch ein geändertes Leiterbahnlayout verwirklicht werden.
Abstract:
A high-frequency module device constituting a communication function module comprises a base substrate part (2) having a multilayer structure of pattern wiring layers (6a, 6b, 9a, 9b) and dielectric insulating layers (5, 8, 11) and a high-frequency element part (4) having an inductor element (20) formed over a build-up formation surface formed by planarizing the uppermost layer of the base substrate part (2), with an insulating layer (19) being interposed between the inductor element (20) and the build-up formation surface. A region (30) where the pattern wiring layers (6a, 6b, 9a, 9b) of the base substrate part (2) are not present is provided from the uppermost layer of the base substrate part (2) to the intermediate portion in the direction of the thickness. In the high-frequency element part (4) disposed right above the region (30), the inductor element (20) is provided.
Abstract:
Bei einem Verfahren zum Herstellen eines Formbauteils (2A-2G) mit einer integrierten Leiterbahn (10) wird auf einem Trägerbauteil (4) insbesondere mit Hilfe des Flammspritzens oder des Kaltgasspritzens eine Leiterbahn (10) erzeugt. Hierzu wird die Oberfläche des Trägerbauteils (4) selektiv entsprechend einem vorgesehenen Verlauf der Leiterbahn (10) behandelt, so dass die oberfläche Bereiche unterschiedlicher Haftung aufweist. Im vorgesehen Verlauf der Leiterbahn (10) wird eine Keimschicht (26) aufgetragen, auf die dann wiederum die eingentiliche Leiterbahn (10) aufgebracht wird. Dadurch ist ein sehr flexibles und kostengünstiges Herstellen eines Formbauteils (2A-2G) mit einem integriertem Leiterbahnmuster möglich. Insbesondere im Kraftfahrzeug-Bereich können spezielle Kundenwünsche zeitnah und problemlos durch ein geändertes Leiterbahnlayout verwirklicht werden.

A circuit body block (2), incorporating film-forming elements (12) (13) (17) in a wiring layer, is mounted on a base substrate (3) to constitute a wiring device. The circuit body block (2) has a semiconductor chip (62) mounted on the surface and is attached on a base substrate (64) to constitute a semiconductor device.
