FIG. 4 shows how in such an array a square chip 1′ replaces a defective chip 1″. The regularly arranged chips 1 have a mean distance p from each other. The average distance between the chips 1 and the first and second electrical repair contacts 15 and 17 or the repair chips 1′ is d. For example, d≤0.5 p, in particular d≤0.1 p.

FIG. 5 shows a further example of a device according to the invention as an array of electrical contacts on a common carrier T. The respective electronic switches 11 are not shown, but can be formed on the carrier T, for example as an integrated circuit. In an X-Y plane, first standard electrical contacts 7 and first and second electrical repair contacts 15 and 17 are arranged to form a grid or field or array. These are required to produce an array as shown in FIG. 4. Here, first and second electrical repair contacts 15 and 17 are arranged in the X-Y plane with a first spacing d adjacent to a respective first standard electrical contact 7, and likewise here, first and second electrical repair contacts 15 and 17 together with an adjacent first standard electrical contact 7 form a module, a plurality of such modules being arranged with a second spacing p adjacent to each other along an X-axis and with a third spacing q adjacent to each other along a Y-axis. According to FIG. 5, instead of chips 1, respective first standard electrical contacts 7 integrated to a common carrier T are shown.

FIG. 6 shows another example of a device according to the invention as an array of electrical contacts on a common carrier T. In contrast to FIG. 5, first standard electrical contacts 7 are used here, the design of which corresponds to the design of the first and second electrical repair contacts 15 and 17. Accordingly, such modules are arranged along an X-axis at an average distance p and along a Y-axis at an average distance q from each other. In this way, a corresponding grid or array comparable to FIG. 5 or FIG. 4 is formed. FIG. 6 shows that a respective first electrical standard contact 7 can be generated from two contacts, for example. In particular, such standard contacts 7a and 7b can be shaped and formed identically to the two repair contacts 15 and 17. This simplifies a production of such a grid as well as a placement of a respective chip 1 and 1′ on the corresponding electrical contacts.

FIGS. 7A to 7D and 7F and 7G show examples of first and second electrical repair contacts 15 and 17 compared to a first standard electrical contact 7 in FIG. 7E. FIGS. 7A, 7B, 7C and 7D show examples of two repair contacts 15 and 17 on which a repair chip 1′ can be placed. FIG. 7A shows two equal-area first and second electrical repair contacts 15 and 17 extending spatially in an X-Y plane along a Y-axis. FIG. 7B shows a rectangular shape of a first electrical repair contact 15 also extending in the Y-direction, next to which another rectangular shape of a second electrical repair contact 17 also extending in the Y-direction is arranged. The first electrical repair contact 15 is spaced from the second electrical repair contact 17 by an elongated interruption strip. The surfaces of the first and second electrical repair contacts 15 and 17 together with the interruption strip form a square. FIG. 7C shows a square configuration of the first electrical repair contact 15. This first electrical repair contact 15 is spaced from the second electrical repair contact 17 on two side lines by means of two corresponding interruption strips, the surfaces of the first electrical repair contact 15 and the second electrical repair contact 17 also forming a square together with the interruption strips. FIG. 7D shows an example in which a first electrical repair contact 15 may be arranged within a second electrical repair contact 17. According to this example, the first electrical repair contact 15 is formed as a circle around which the second electrical repair contact 17 is arranged in the form of a ring with a spacer area which is annular.

FIG. 7E shows an example of a square extension of the standard electrical contact 7, where the first standard electrical contact 7 has a surface A1. In contrast, FIG. 7F shows an arrangement of first electrical repair contact 15 and second electrical repair contact 17. These rectangular configurations have a length Y as shown in FIG. 7A. Both rectangles of the first and the second electrical repair contact 15 and 17 form a total area A2. FIGS. 7E and 7F also show an example of a spacing between standard contact 7 and repair contact 15 and 17. A spacing is indicated here as d. FIG. 7E shows an example of a standard electrical contact 7 or 9 with a total area A1. FIG. 7F shows an example of two adjacent repair contacts 15 and 17, the latter consisting of two contact surfaces and comprising a total area A2. The standard contact comprising an enclosing area of A1. For example, the amount of |A1−A2|≤0.5 (A1+A2)/2. In particular, it may be that |A1−A2|≤0.1 (A1+A2)/2. This means that here the enclosing areas of the two contact types differ by at most 50% and at most 10%, respectively.

FIG. 7G shows that more than two contacts may be formed in the plane of the first electrical repair contact 15 and the second electrical repair contact 17. FIG. 7G shows, in addition to the first electrical repair contact 15 and the second electrical repair contact 17, a further electrical repair contact 21. That is to say, a repair chip 1′ can be placed on a plurality, in this case greater than two, of electrical repair contacts whose surfaces or contact areas can all be arranged in one plane. In this way, further electrical contacts can be produced and in this way, for example, further electronic switches can be actuated. A repair chip 1′ can thus electrically connect a plurality of electrical contacts or corresponding electrical contact surfaces and thus contacts. In this way, any number of electrical contacts can be produced, which can be used in different ways. In principle, further electronic switches can be opened or closed. In FIG. 7G, electrical repair contacts 15 and 17 are rectangles extending in the Y-direction, and a further electrical repair contact 21 is arranged above them in the Y-direction. The latter forms a rectangle extending in the X-direction. All rectangular corners can be rounded.
