[0002] To ensure the performance of the integrated circuit, the parameters of each device in the integrated circuit need to be tested, and the resistance value of the resistance element needs to be measured. At present, the resistance value of the resistance element is generally measured by using the volt-ampere method, that is, the voltage across the resistance element is measured by using a voltmeter in parallel, and the current intensity passing through the resistance element is measured by using an ammeter in series, and then the resistance value is measured by using the Ohm's law: R=U / I.

[0003] In the related art, the resistance element generally includes two electrode parts, and the two electrode parts are used as detection points for voltage detection and current detection, and the measurement result is affected by the voltage drop, resulting in deviation in resistance value measurement. Especially when measuring the resistance value of a high-precision resistor to be measured, the measurement result is not accurate. In order to further ensure the performance of the integrated circuit and ensure the accuracy of the resistance value measurement, it is particularly important to miniaturize the area size of the resistance element.

Obviously, the described only shows some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features.

[0031] The embodiment discloses a resistance element, referring to the drawings Figures 1-3 , comprising a resistance body 1, the first surface of the resistance body 1 is divided into an insulating area 101 and a plurality of non-insulating areas 102 arranged symmetrically, wherein the number of non-insulating areas 102 is 2N, N is an even number and greater than or equal to 2; any two non-insulating areas 102 on the same side are defined as a measurement group 5; the insulating area 101 is provided with an insulating part 2, the non-insulating area 102 is provided with a conductive part 3, the conductive part 3 is connected with an electrode part 4 away from one side of the resistance body 1, the electrode part 4, the conductive part 3 and the resistance body are sequentially stacked; the positions of the electrode parts 4 on the same side in any two measurement groups 5 are connected with the resistance body 1. In this embodiment, the insulating part 2 can be selected from insulating ink or silicon dioxide material; the conductive part 3 can be selected from conductive metal or metal alloy, such as copper, silver, gold and other conductive metal materials or metal alloy including copper, silver, manganese, gold and other materials.

[0032] The embodiment divides the first surface of the resistance body into an insulating area 101 and a plurality of non-insulating areas 102 arranged symmetrically, wherein the number of the non-insulating areas 102 is 2N, N is an even number and is greater than or equal to 2; and any two non-insulating areas 102 on the same side are positioned as a measurement group 5. When the resistance value is measured by the voltammetry method, the tester connects two electrode parts 4 in one test group 5 in parallel with a voltmeter and connects two electrode parts 4 in another test group 5 in series with an ammeter. Since the positions where the electrode parts 4 in the two measurement groups 5 on the same side are connected with the resistance body 1 have equal potentials, i.e. there is no voltage drop between the electrode parts 4 in the two measurement groups 5, the voltage measured by the voltmeter is not disturbed, so the resistance value of the resistance element calculated from the voltage measured by the voltmeter and the current measured by the ammeter is accurate. In addition, since the number of the non-insulating areas 102 in the embodiment is designed to be 2N, it means that a plurality of measurement groups 5 can be arranged on the resistance element, so that a plurality of resistance value data can be obtained by measuring a plurality of measurement groups 5 when the resistance value is measured by the voltammetry method, and finally the final resistance value data can be obtained by averaging the plurality of resistance value data. It can be understood that, in the experimental measurement process, averaging a plurality of data is also one of the effective methods to improve the accuracy of the measurement result. Of course, according to the above description, the number of the non-insulating areas 102 is set to four, and the number of the measurement groups 5 is two, which can meet the minimum resistance value measurement requirement. The number of the non-insulating areas 102 is four in the present application.

[0033] In addition, considering the processing requirements of some manufacturers, the number of the electrode parts 4 only needs to be set to two, so the present application can also print a layer of conductive material on the electrode parts 4 on the same side in the two measurement groups 5 after the resistance value measurement by electroplating or other methods, so that the two electrode parts 4 are connected to each other, so that the final resistance element product only has two electrode parts 4 (as shown in FIG. 6). Figure 4

[0034] At the same time, the electrode part 4, the conductive part 3 and the resistance body in the embodiment are sequentially stacked, i.e. the electrode part 4 and the conductive part 3 are arranged in the upper region of the resistance body, without occupying the peripheral region of the resistance body to arrange the electrode part 4 and the conductive part 3, thereby reducing the space occupancy rate of the resistance element and achieving the purpose of miniaturization of the area size of the resistance element.

[0035] As a preferred scheme of the above embodiment, the areas of the two electrode parts 4 in the symmetric arrangement relationship are equal. In this way, in order to ensure that the positions where the electrode parts 4 on the same side in any two measurement groups 5 are connected with the resistance body 1 have equal potentials, the areas of the two electrode parts 4 in the symmetric arrangement relationship need to be equal, because equal areas can ensure the uniformity of the current.

[0036] ​As a preferred solution of the above embodiment, the electrode part 4 covers the second projection area of the conductive part 3 towards the resistance body. In this way, the electrode part 4 can cover the conductive part 3 to transmit current. Specifically, the area of the electrode part 4 is 1-1.5 times the area of the conductive part 3 to ensure that the electrode part 4 can effectively cover the conductive part 3.

[0037] As a preferred solution of the above embodiment, the non-insulating area 102 is arranged at the edge of the first surface (as shown in FIG. 1B), or the non-insulating area 102 is arranged at the middle of the first surface (as shown in FIG. 1C). Figure 1 Figure 5 When the non-insulating area 102 is arranged at the middle of the first surface, on the one hand, the non-insulating area 102 is surrounded by the insulating area 101 on all sides, so that the insulating part 2 forms a structure similar to a fence, which is conducive to accurately filling the conductive metal or metal alloy into the non-insulating area 102 and avoiding the conductive metal or metal alloy exceeding the range of the non-insulating area 102; on the other hand, the electrode part 4 is shrunk into the middle area of the resistance element, so that the integrated circuit can be routed and arranged at the peripheral area of the resistance element, which is conducive to saving the routing space of the integrated circuit and further catering to the miniaturization trend of the integrated circuit.

[0038] As a preferred solution of the above embodiment, referring to FIG. 1D, each non-insulating area 102 includes a plurality of sub-non-insulating areas 1021, and the plurality of sub-non-insulating areas 1021 are arranged in a rectangular array, a circular array, or a linear array. Figure 6 In this way, in order to avoid the failure of the conductive part 3 in the non-insulating area 102 leading to the failure of current transmission and the failure of the resistance element, a plurality of sub-non-insulating areas 1021 are arranged in each non-insulating area 102. In this way, even if the conductive part 3 in one of the sub-non-insulating areas 1021 fails, the current can still be transmitted through the remaining sub-non-insulating areas 1021, ensuring the normal use of the resistance element. It should be additionally explained that in order to ensure that the positions where the electrode parts 4 on the same side of any two measurement groups are connected to the resistance body 1 have the same potential, the number of sub-non-insulating areas 1021 in each non-insulating area 102 should be equal.

[0039] The embodiment also discloses an integrated circuit including the resistance element of the above embodiment. Since the integrated circuit adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0040] It should be noted that other contents of the resistance element disclosed in the present application are prior art, which will not be repeated here.

[0041] ​The above merely describes optional embodiments of the present application, and does not limit the patent scope of the present application, and any direct / indirect application of the present application to other related technical fields is included in the patent protection scope of the present application.
