Definitions
- the invention relates to electronic components, as well as a semiconductor wafer and a component carrier for producing such components, which have a semiconductor chip with an integrated circuit and with a chip backside, which is mounted on a chip carrier.
- microcracks or microcracks form up to a mechanical delamination of the semiconductor chip from the chip carrier.
- the formation of microcracks or microcolumns creates areas in which moisture accumulates and stores so that malfunctioning of the electronic component can occur.
- the object of the invention is to provide an electronic component in which voltage peaks between the semiconductor chip and the chip carrier are degradable, without electronic malfunction of the electronic component occur.
- the electronic component has a semiconductor chip with an integrated circuit Chip top and with a chip back on.
- This semiconductor chip is arranged on a carrier top side of a chip carrier, which has a carrier back side.
- the chip back side and the carrier top side each have a magnetic layer and at least one of the two layers is permanently magnetic.
- the permanent magnetic state is achieved by appropriate magnetization of hard magnetic materials. During the magnetization, different polarities, different layer regions can be achieved simultaneously by aligning the Weis domains in the hard magnetic material.
- the layer remains magnetic and can be fixed by a permanent magnetic layer.
- the two superimposed layers on the back of the chip and on the upper side of the carrier can be moved laterally despite the magnetic transversal fixation. This ensures that at different thermal expansion of the semiconductor chip and chip carrier no voltage spikes occur in the electronic component, since the component top can move laterally with respect to the chip back under thermal stress and yet maintained an intense thermal contact between the chip back and carrier top, so that malfunction avoided become.
- the magnetic layer material used can be ferromagnetic materials and / or ferrimagnetic materials.
- ferromagnetic materials iron, nickel, cobalt and / or gadolinium can be contained as a rare earth in the magnetic layer, while used as ferrimagnetic materials oxide ceramics.
- the ferrimagnetic Materials are especially intended for the formation of permanent magnetic layers.
- both the magnetic layer on the chip back side and the magnetic layer on the carrier top side are permanently magnetic.
- the permanent magnetic layers have structures which are aligned radially symmetrically, for example, radially toward a point of symmetry and have an alternating polarity.
- Such a structuring and polarization of the permanent magnetic layers has the advantage that when a semiconductor chip with a correspondingly structured magnetic layer on its rear side is placed on a chip carrier with a correspondingly structured permanent magnetic layer with corresponding polarity reversal on its carrier top side, the semiconductor chip is automatically placed on the chip carrier centered and positioned.
- the production outlay can thus be reduced, especially as micro-manipulation of the semiconductor chips can be dispensed with.
- a further aspect of the invention relates to a semiconductor chip wafer for producing a plurality of semiconductor chips, wherein the semiconductor wafer has semiconductor chip positions arranged in rows and columns. On its wafer top side, the semiconductor chip is integrated in the semiconductor chip positions
- This magnetic layer can be permanently magnetic and, in particular, this permanent magnetic layer can be structured in each of the semiconductor chip positions in such a way that regions of different polarity are present radially symmetrically and / or concentrically.
- Such a semiconductor wafer has the advantage that it produces a multiplicity of electronic semiconductor chips by separation along parting lines of the semiconductor chip positions arranged in rows and columns, which are suitable for application to a correspondingly prepared semiconductor chip carrier having a magnetic layer and / or with a permanent magnetic layer are.
- the semiconductor wafer with its structures on the semiconductor chip back side has the advantage that a magnetic layer is already present for many semiconductor chips at the same time.
- a further aspect of the invention relates to a component carrier which has component positions arranged in rows and columns, the component positions having chip carriers with chip carrier top sides and chip carrier back sides.
- the chip carrier tops can have magnetic layers and / or permanent magnetic structures with regions of different polarity in a radially symmetrical and / or concentric arrangement.
- Such a component carrier has the advantage that it can be equipped with appropriately prepared semiconductor chips, and although these semiconductor chips are fixed transversely by the magnetic attraction, but can move laterally relative to the chip carrier under thermal stress.
- a radially symmetrical and / or concentric arrangement of regions of permanent magnetic layers has the advantage that the semiconductor chip remains centered on the chip carrier despite its thermal expansion of the chip carrier and the semiconductor chip with its center on the chip carrier.
- a method for producing a semiconductor wafer having a plurality of semiconductor chip positions for a plurality of electronic components has the following method steps. First, a semiconductor wafer is provided with semiconductor chip positions arranged in rows and columns and with a wafer top side and with a wafer backside. Subsequently, a magnetic layer is applied to the back of the wafer. This magnetic layer can additionally be patterned in the semiconductor chip positions, so that it has radially symmetric and / or concentric regions. Subsequently, these areas can be magnetized differently, so that different poled permanent magnetic areas arise. Such a structuring in the semiconductor chip positions is only necessary if, after the semiconductor wafer has been separated into individual semiconductor chips, these are to be applied self-centering to a corresponding chip carrier.
- a method for producing a component carrier with a plurality of component positions for a plurality of electronic components has the following method steps. First, a component carrier blank with component positions arranged in rows and columns of a component carrier top side and a component carrier rear side is provided.
- This component carrier blank may comprise a non-magnetic copper or copper alloy plate. But it can also have a copper-clad circuit board.
- a magnetic layer is applied to the component carrier top side. If this component carrier is prepared for semiconductor chips which already have permanent-magnetic layers on their rear sides, it is sufficient to apply only one magnetic layer to the component carrier. However, then there is no automatic centering of the semiconductor chip on the chip carrier. It must rather be positioned with a micromanipulator of the semiconductor chip on the component carrier.
- the magnetic layer on the component carrier top side is first patterned and then the structured magnetic layer is magnetized into differently poled permanent magnetic regions.
- radially symmetric and / or coaxially aligned regions can be provided in order to ensure automatic positioning and centering of semiconductor chips on the component carrier.
- This method has the advantage that electronic components are formed which are not disturbed even when the semiconductor chips are displaced relative to the carrier material due to thermal stress electrical contact with the carrier material, since a lateral displacement between the magnetic layers is possible at any time, without the contact pressure between the magnetic layers to reduce or increase the contact resistance. This creates an electronic component whose functionality is not impaired by thermal loads.
- Chip carrier currently the technique of gluing or soldering is used. This compound is rigid in all directions, with the result that the adhesive force between the carrier and chips abruptly as soon as a critical stress in the material is exceeded. It creates a gap in which moisture can accumulate, which leads to failure of the component. Furthermore, even the adhesives between the semiconductor chip and the chip carrier tend to absorb moisture, which may affect the functionality of an electronic component.
- connection is realized which permits a lateral displacement of the connection partners of semiconductor chip and chip carrier, without the transverse connection force decreasing.
- the chip carrier of the component carrier serves as a mounting surface for a rear side of the semiconductor chip coated with a magnetic layer. Only one of the two contact partners must be permanently magnetic, ie actively generate a magnetic field. It is therefore sufficient if each of the other partner is magnetizable.
- both components are bonded together. the fixed.
- By fine structuring of the magnetic regions, self-centering of the semiconductor chip on the chip carrier can also be achieved.
- FIG. 1 shows a basic cross section through a semiconductor chip 1 on a semiconductor chip carrier 4.
- the semiconductor chip 1 has a chip top side with an integrated circuit whose contact surfaces 9 are connected via bonding connections 10 to external contacts (not shown) of the electronic component.
- a chip back 3 has a magnetic layer 7.
- the semiconductor chip 1 is arranged on a chip carrier 4, which in turn has a rear side 6 and an upper side 5.
- a permanent magnetic layer 8 is arranged, which is magnetized such that the magnetic layer 7 is attracted to the chip back side 3 of the semiconductor chip 1 by the permanent magnetic layer 8 and fixed on the carrier top side 5 of the chip carrier 4.
- both magnetic layers 7 and 8 have structured permanent magnetic regions and these are structured radially symmetrically or concentrically, the semiconductor chip 1 is automatically aligned, centered and fixed on the chip carrier 4 in a predetermined manner.
