Meander-shaped conductor system, especially as a reading line for thin-film storage

/ Ke M BpIsI ViQ

This relates to a meander-shaped conductor line covering a predetermined area, which is applied to an insulating substrate J) with the aid of masks, so / ie to a set of masks for producing such a conductor line.

Such meandering conductor tracks are in particular grounded as a Lecc line for storage, especially for superconducting Thin film storage used. In particular, such a conductor track covers the area with individual ones Sections of the meander that are directed parallel to one of the surface diagonals.

There are already various meander guides of the Leitorzugeo for a read line of a thin-film storage system has been specified. Task of the present S

■ is to specify such a conductor run that has a low inductance, has low susceptibility to interference and whose outputs are in particular as close as possible to each other, wherein the conductor run can be made with no more than two masks on an insulating base, in particular by vapor deposition. .

These requirements are fulfilled by a meandering line guide xst geraäß characterized in that the conductor track is substantially of the portions, extend rectilinearly and parallel to each other from a r edge of the surface to another edge of the surface and which are distributed so that a current on The path from one input connection to the other input connection essentially runs in such a way that it passes through loops called "outer loops", each of which encloses a loop of its path called "inner loop" almost completely without crossing, with at least one Part of such an outer loop is also part of an inner loop. In particular, the area is determined by the one of the Singang-

Outgoing connections straight section in two halves divided, in which the ladder route is essential in each case running parallel to this division, which correspond to - (_. the half from inne2i outwards and again progressing inwards nit, as described above, alternately overlaps one of the surrounding loops of the conductor = preferably the connections ran directly adjacent to one another on the edge of the area.

The first task that led to this was to find a meander guide that can be produced with just two masks, preferably by vapor deposition. Each of the masks should only have openings that

do not affect the stability of the masks. Such impairments occur, for example, when the strip-shaped Openings to form a long tongue or similar structure in the covering part of a mask = Indeed one could. as the principle described above for a measurement can be found, according to -QP The conductor run can be made with only two masks, in which the recessed openings are only rectilinear Form stripes that have no contact with each other and either only briefly in relation to each other to the linear dimensions of the surface (mask 1) or which are exclusively parallel to each other (mask 2). Such masks not only have great mechanical stability, they also have, associated with this, a Much greater accuracy in its dimensions »Such a single mask 1 or 2 can of course also be used on its own consist of several pieces to be laid one on top of the other, of which e.g. a mechanically stable ^ thick P3 larger gaps a thin film with the exact gaps bears and supports «

A further, not insignificant advantage of the invention is the reduction in the drawing work required on the so-called coordinatograph to produce the patterns for the respective masks.
