Description

[0001] The present invention relates to an electronic component.

[0002] An electronic component is known, for example, from DE 10 2011 010 611 A1. From JP H10 - 208 971 A, a multilayer component is known in which the inner electrodes taper continuously towards the opposite outer electrode. From JP H10 - 64 703 A, a multilayer component is known in which the inner electrodes taper only in a peripheral region near an opposite outer electrode.

[0003] One task to be solved is to specify an improved electronic component.

[0004] This problem is solved by the electronic component with the features of claim 1 and claim 11. Advantageous embodiments and further developments are the subject of the dependent claims.

[0005] An electronic component comprises a dielectric base, a first inner electrode extending into the dielectric base, a second inner electrode extending into the dielectric base, a first outer contact, and a second outer contact. The first outer contact is electrically connected to the first inner electrode and electrically isolated from the second inner electrode, and the second outer contact is electrically connected to the second inner electrode and electrically isolated from the first inner electrode.The second inner electrode overlaps with the first inner electrode to form an electrically active region, such that a lateral extent of the electrically active region is defined at least partially by the lateral extents of the first and second inner electrodes in the overlap region, the lateral extent of the first inner electrode continuously increases with increasing distance from the end of the first inner electrode facing the second external contact up to a maximum lateral extent, and the lateral extent of the second inner electrode continuously increases with increasing distance from the end of the second inner electrode facing the first external contact up to a maximum lateral extent.

[0006] A portion of the dielectric base body can be positioned between the aforementioned end of the inner electrode and the outer contact.

[0007] The dielectric base body can be a ceramic base body.

[0008] The external contact could be an external electrode.

[0009] The lateral extent of the inner electrode can refer to the width of the inner electrode.

[0010] One advantage of the proposed electronic component is that, during operation of the electronic component, electric fields at an edge of the external contact or of the electronic component can be kept low.

[0011] This prevents or limits the diffusion and / or migration of substances, such as atoms, molecules, or ions, particularly chlorine-containing compounds found, for example, in fluxes of solder materials, into an electrically active area of ​​the electronic component during operation. Such diffusion or migration can negatively alter the electrical properties of the electronic component or even lead to its failure. The described design advantageously provides diffusion and / or migration protection for the electronic component.

[0012] In a preferred embodiment, the electronic component is a varistor, a capacitor, for example a ceramic multilayer capacitor, a PTC component, an NTC component, a piezoelectric component and / or a component comprising a ferrite.

[0013] In one embodiment, the electronic component is a surface-mounted or surface-mountable component.

[0014] Preferably, the free end of the second inner electrode faces the first outer contact, and the free end of the first inner electrode faces the second outer contact. Viewed from above, the first and second inner electrodes are preferably arranged between the first and second outer contacts.

[0015] Sections of the dielectric base can be arranged between the free end of the second inner electrode and the first outer contact, and between the free end of the first inner electrode and the second outer contact. Preferably, the first inner electrode and the first outer contact are identical to the second inner electrode and the second outer contact. Viewed from above, the first and second inner electrodes can be arranged symmetrically with respect to an axis parallel to the lateral extent of the electronic component. Furthermore, the first and second outer contacts can also be arranged symmetrically with respect to this axis. This configuration advantageously allows for a symmetrical arrangement of both the inner electrodes and the outer contacts, as well as a symmetrical electric field distribution during operation, i.e., when an electric operating field is applied to the electronic component.Furthermore, this design minimizes the electric fields occurring at the edges of the first and second external contacts during operation of the electronic component. This prevents diffusion and / or migration of substances, such as atoms, molecules, or ions, particularly chlorine-containing compounds found in fluxes of solder materials, in the area of ​​the external contacts and in electrically active areas of the electronic component, caused by electric fields.

[0016] The second inner electrode extends into the dielectric base. Furthermore, the second inner electrode overlaps the first inner electrode to form an electrically active region. Viewed from above, this electrically active region can be defined by the overlap of the first and second inner electrodes. A lateral extent of the electrically active region is defined by the lateral extents of the first and second inner electrodes within the overlap region. In particular, a lateral extent of the electrically active region is given by the lateral extent of the first and / or the second inner electrode. Preferably, the regions with varying lateral extents of the first and second inner electrodes define the overlap region. Depending on the arrangement of the first and second inner electrodes, the electrically active region can be arranged symmetrically with respect to the aforementioned axis.

[0017] The free end or an end region extending from it of the first inner electrode preferably overlaps with the free end or an end region extending from it of the second inner electrode to form the electrically active region.

[0018] The dielectric base body is preferably arranged in the overlap area between the first and the second inner electrode.

[0019] The lateral extent of the first and / or second internal electrode increases with increasing distance from the respective other external contact, at least in certain areas or uniformly.

[0020] The lateral extent of the first and / or second inner electrode also increases with increasing distance from the end of the first or second inner electrode facing the other external contact, at least in some areas or uniformly.

[0021] In other words, when viewed from above, the first and second inner electrodes have at least partially flat surfaces. The first and second inner electrodes can taper towards the respective outer contact. This design advantageously allows for a simple design of the first and / or second inner electrode. Furthermore, this design facilitates the simple fabrication of the first and second inner electrodes.

[0022] The lateral extent of the first inner electrode increases continuously with increasing distance from the end of the first inner electrode facing the second external contact, up to a maximum lateral extent.

[0023] The lateral extent of the second inner electrode increases continuously with increasing distance from the end of the second inner electrode facing the first external contact, up to a maximum lateral extent.

[0024] In one embodiment, the maximum lateral extent of the first inner electrode differs from the maximum lateral extent of the second inner electrode. In one embodiment, the ratio of the maximum lateral extent of the first inner electrode to the maximum lateral extent of the second inner electrode takes on values ​​between 0.5 and 1.5, preferably between 0.7 and 1.3. Maximum lateral extent can refer to the maximum extent within and / or outside the electrically active region.

[0025] In a preferred embodiment, the maximum lateral dimensions of the first and second inner electrodes are identical. This allows the first and second inner electrodes to be advantageously designed symmetrically and manufactured simply. Accordingly, each of the first and second inner electrodes has a region in which the lateral dimension increases or varies.

[0026] In a preferred embodiment, the first and second inner electrodes each have a region in which their lateral extent is constant with increasing distance from the respective external contact. In this region, the first and second inner electrodes preferably each exhibit their maximum lateral extent. Viewed from above, this region of the first and second inner electrodes is preferably located, at least partially, between the electrically active area and the external contact to which the respective inner electrode is electrically connected. This design allows for a compact form of the electronic component, particularly in the lateral direction.

[0027] In a preferred embodiment, the region with varying lateral extent of the first and / or the second inner electrode overlaps at least partially with the region of constant lateral extent of the other inner electrode. According to this embodiment, the largest possible overlap region, or the largest possible electrically active region of the electronic component, can be formed. The region with varying lateral extent of the first and / or the second inner electrode preferably overlaps at least partially with the region of varying lateral extent of the other inner electrode.

[0028] In one embodiment, the free end of the first and / or second inner electrode overlaps at least partially with the region of varying lateral extent of the respective inner electrode. This preferably results in the respective free end of the first and / or second inner electrode having a reduced lateral extent compared to the region of constant lateral extent of the respective inner electrode.

[0029] Alternatively, the lateral extent of the first and second inner electrodes can also increase with increasing distance from the respective external contact along their entire length. This lateral extent can extend from the free end of each inner electrode to the external contact to which the respective inner electrode is electrically connected.

[0030] The length of an inner electrode can refer to a direction perpendicular to the aforementioned lateral dimension. The first and second outer contacts can be spaced apart along this direction.

[0031] In a preferred embodiment, the lateral extent of the first and second inner electrodes increases from the end facing the other outer contact, i.e., the second and first outer contact respectively, to at least half the total length of the first and second inner electrodes, respectively. This embodiment advantageously allows the lateral extent of the first and second inner electrodes to increase over a large length range. This enables particularly efficient diffusion and / or migration protection for the electronic component.

[0032] In one embodiment, the lateral extension of the first or second inner electrode increases from the end facing the other external contact, i.e., the second or first external contact, respectively, to at least half the total length of the first or second inner electrode, respectively.

[0033] In a preferred embodiment, the overall length of the first and / or the second inner electrode is less than four-fifths of the distance between the first and second outer contacts. This design advantageously achieves a distance between the inner electrode and the other outer contact that, during operation of the electronic component, prevents the formation of electric fields that could cause the migration or diffusion of substances mentioned above. In a preferred embodiment, the overall length of the first and / or the second inner electrode is greater than three-fifths of the distance between the first and second outer contacts. In particular, this design allows for the largest possible electrically active area or a more compact design of the electronic component.

[0034] In a preferred embodiment, the lateral extent of the end of the first inner electrode facing the second outer contact is less than half the maximum lateral extent of the second inner electrode. Preferably, however, the end of the first inner electrode facing the second outer contact is blunt, so that it still has a certain lateral extent. In particular, this design can prevent the formation of large electric fields, or fields that are detrimental to the operation of the electrical component, at an edge of the first and second outer contacts and / or in a region between the free end of the first or second outer contact and the outer contacts facing these ends.

[0035] In a preferred embodiment, the lateral extent of the end of the second inner electrode facing the first external contact is less than half the maximum lateral extent of the first inner electrode.

[0036] In a preferred embodiment, the electronic component has a plurality of first and second internal electrodes.

[0037] In a preferred embodiment, the first and second inner electrodes are inner electrode layers. Preferably, the first and second inner electrode layers are stacked together.

[0038] In a preferred embodiment, the first inner electrodes are electrically connected to the first outer electrode and electrically isolated from the second outer electrode. The second inner electrodes are also electrically connected to the second outer electrode and electrically isolated from the first outer electrode. This embodiment allows the electronic component to be advantageously implemented as a multilayer device. This enables the advantages of multilayer devices, such as piezoelectric devices or ceramic capacitors, to be utilized for the electronic component. Preferably, the first and second inner electrodes overlap completely when viewed from above. The first and second inner electrodes preferably interlock alternately without touching each other.The dielectric base is preferably arranged in regions between the first and second inner electrodes. Furthermore, the dielectric base can be arranged between adjacent first and second inner electrodes.

[0039] The electronic component can be designed such that the distances between adjacent internal electrodes are in the range between 50 µm and 500 µm.

[0040] In a preferred embodiment, the electronic component has first and / or second shielding electrodes, wherein the first shielding electrodes are electrically conductively connected to the first external contact and the second shielding electrodes are electrically conductively connected to the second external contact. The first and / or second shielding electrodes are arranged outside the electrically active area, but can, when viewed from above, overlap at least partially with the electrically active area. This allows the area to be advantageously shielded against electric fields.

[0041] In a preferred embodiment, the first shielding electrodes extend longitudinally over more than two-fifths of the total length of the first inner electrodes. The second shielding electrodes can extend longitudinally over more than two-fifths of the total length of the second inner electrodes. The first and / or second shielding electrodes preferably extend into the dielectric base body.

[0042] During operation of the electronic component, the first and second shielding electrodes are preferably at the same electrical potential as the first and second external contacts, respectively. This design allows for particularly effective shielding of the electrically active area against electric fields during operation of the electronic component. Advantageously, the described design can achieve diffusion and / or migration protection of the electronic component, especially within a volume defined by the first and / or second shielding electrodes.

[0043] In a preferred embodiment, the total lengths of the first and second inner electrodes are the same.

[0044] The design of the inner and / or shielding electrodes advantageously prevents the aforementioned migration and / or diffusion of atoms, ions or molecules into or within the electrically active area.

[0045] In one embodiment, the electronic component has an enclosure. The enclosure can be a glass layer or a glass layer. The dielectric base can be embedded in the enclosure. The external contacts of the electronic component can be outer caps. Each external contact can also be electrically connected to an electrical supply line. The electronic component can preferably be electrically contacted via these supply lines. The enclosure can enclose the dielectric base and the first and second external contacts of the electronic component such that the enclosure is only free of enclosing material in the areas where the external contacts are connected to the electrical supply line. The enclosure can, for example, be perforated by the electrical supply lines to facilitate electrical contact with the electronic component.This enclosure offers the advantage of additional diffusion protection, for example of the electrically active area, against the influences mentioned above. Preferably, the enclosure comprises glass or consists entirely of glass.

[0046] In a preferred embodiment, the first and / or second inner electrodes or the first and / or second shielding electrodes are designed and arranged such that the magnitudes of the electric field after the application of an electric operating field between the first and the second outer contact are less than 6 volts per millimeter at an edge of the first and the second outer contact.

[0047] In one embodiment, the electronic component is designed according to one of the following package sizes: 0201, 0402, 0504, 0603, 0805, 0907, 1008, 1206, 1210, 1411, 1515, 1608, 1812, 1825, 2010, 2220, or according to a package size that is smaller than any of the aforementioned package sizes. The package sizes are listed in descending order of size.

[0048] A package size smaller than 0603 can refer to one of the packages 0201, 0402, or 0504 and / or mean that the smaller package has a smaller footprint than the reference package. This can refer in particular to the surface area of ​​a package and / or a solder pad corresponding to that package size, for example, on a printed circuit board or a semiconductor device, such as a chip. The 0603 package can correspond to a length of 1.6 ± 0.1 mm and a width of 0.8 ± 0.1 mm.

[0049] In a preferred embodiment, the electronic component is designed according to package type 0603 or according to a smaller package type.

The electrically active region 8 is bounded by the first inner electrode 2 and the second inner electrode 5. An example is shown in Fig. The minus sign at the first external contact 3 indicates a negative electrical potential, which, for example, can be present at the first external contact 3 during operation of the electronic component 100. Accordingly, the plus sign at the second external contact 6 indicates a positive electrical potential.

[0053] Fig. Figure 3A shows a schematic side sectional view of an electronic component 100 with a plurality of first inner electrodes 2 and second inner electrodes 5. The first inner electrodes 2 and the second inner electrodes 5 are each inner electrode layers arranged alternately and spaced apart from one another in a stack. The first inner electrodes 2 and the second inner electrodes 5 overlap completely in the electrically active region 8. The first inner electrodes 2 and the second inner electrodes 5 also extend into the dielectric base body 1. The electronic component 100 further comprises first shielding electrodes 11 and second shielding electrodes 14. During operation of the electronic component 100, the first and second shielding electrodes 11, 14 are preferably at the same potential as the first and second external contacts 3, 6, respectively.The first and second shielding electrodes 11, 14 extend over a distance C into the dielectric base body 1. The distance C preferably corresponds to more than two-fifths of the total length L of the first and second inner electrodes 2, 5. The first shielding electrodes 11 are electrically conductively connected to the first outer contact 3, and the second shielding electrodes 14 are electrically conductively connected to the second outer contact 6. Furthermore, one of the shielding electrodes 11 and one of the shielding electrodes 14 are arranged on a top and a bottom surface of the electrically active area 8, respectively, to electrically shield sections 15 located between the electrically active area 8 and the first and second outer contacts 3, 6. The electronic component also includes an enclosure 17 as diffusion protection against external influences, materials, or substances. The enclosure 17 is preferably made of glass.Furthermore, the covering 17 encloses or envelops the dielectric base body 1 and the first and second external contacts 3, 6 in such a way that only areas of the first and second external contacts 3, 6 remain free from the covering for the purpose of electrical contacting the electronic component (see also . Fig. 3B). In the areas mentioned, the first and second external contacts 3, 6 can each be electrically connected to an electrical supply line (not explicitly shown).

[0054] Fig. Figure 3B shows a schematic top view of the electronic component 100, which is located in Fig. Figure 3A shows the first inner electrodes 2 and the second inner electrodes 5, which are shown hatched. An overlapping area of ​​the first inner electrodes 2 and the second inner electrodes 5 defines the electrically active area 8.

[0055] The first inner electrodes 2 and the second inner electrodes 5 are each arranged symmetrically and are of identical design. The lateral extent X of the first and second inner electrodes 2, 5 preferably increases to more than half the total length L of the first and second inner electrodes 2, 5, respectively (see also Fig. 1) The vertical dashed lines indicate Fig. 3B defines the length C over which the first and second shielding electrodes 11, 14 extend into the dielectric base body 1.

[0057] Fig. Figure 4A schematically shows a lateral sectional view of a state-of-the-art electronic component 101.

[0058] Because the distances D of the first and second inner electrodes 2, 5 from the respective other outer electrode 6, 3 are smaller than the distances B mentioned above, larger electric fields form during the operation of the electronic component 101, for example at an edge 12 of the first or second outer contact, for example in magnitude greater than 6 volts per millimeter, than is the case with the described electronic component 100.

[0059] Fig. Figure 4B shows a schematic top view of the electronic component 101, which is located in Fig. Figure 4A shows the first inner electrodes 2 and the second inner electrodes 5 overlap in an electrically active region 8, with the lateral extents of the first inner electrodes 2 and the second inner electrodes 5 being constant over the total length L of the first and second inner electrodes 2, 5.
