Definitions
- the invention relates to an integrated connection arrangement which contains a substrate, an outer conductive structure remote from the substrate and an inner conductive structure close to the substrate.
- a large number of electronic components are arranged in a main area of the substrate, for example semiconductor components such as transistors.
- Such an integrated circuit arrangement is known, for example, from international patent application WO 03/003458 A2.
- the outer lead structure is a bond pad that contains a bond area and a test area.
- a metallization layer with so-called via's is arranged between the two metallization layers with interconnects. In the via's of this metallization layer, current is conducted in the operation of the integrated circuit arrangement essentially in the normal direction or against a normal direction of the main surface, but not parallel to the main surface or transversely to the normal direction.
- the via's have in common that they mainly have a current flow in the normal direction or opposite to the normal direction of the main area, but not parallel to the main area, that they are parallel with most of their cross-sectional area to the main surface or completely overlapping to an underlying interconnect or to an overlying interconnect, and that sections of a via that do not overlap with an underlying or underlying interconnect, ie Sections offset from the interconnect do not influence the function of the integrated circuit arrangement, ie in particular are not used as an electrically conductive connection which is required for the function of the integrated circuit arrangement.
- the vias of a metallization layer have identical dimensions to one another.
- the interconnects of a metallization layer have clearly different outlines.
- the length is, for example, a multiple of the width of an interconnect.
- connection arrangement which, in particular, has improved electrical properties than known connection arrangements.
- a manufacturing method is to be specified.
- connection arrangement The object relating to the connection arrangement is achieved by a connection arrangement with the features of patent claim 1. Further developments are specified in the subclaims.
- the invention is based in particular on the consideration that with each new technology generation in the manufacture of integrated circuit arrangements, the requirements for metallization increase. Particularly in the case of bipolar and CMOS technologies, very high current densities of, for example, more than one, more than five or more than 10 milliamperes per square micron of web cross-sectional area or very low web resistances are required, despite the smallest dimensions, which are realized with copper metallizations. Since there is still no inexpensive and production-proven assembly technology for Copper surfaces, aluminum has been used as the last level of metallization. However, aluminum has a lower current carrying capacity compared to copper. Based on these facts, an aluminum bond pad can only be loaded with lower absolute currents or is less resistant to electromigration than a copper structure of the same dimensions. The bond pad thus becomes a critical circuit part, which has a significant influence on the life of the entire product. The current densities required will increase in the future. Also be on
- the invention is also based in particular on the consideration that a via metallization layer could be arranged with the connections under a metallization layer.
- the layer thickness at the stages is reduced due to process effects to values that are, for example, approximately 50% of the layer thickness in planar areas. This in turn leads to an increase in the current density at the stage. An increase in current density due to a narrowing of the geometry or thickness and thus locally increased current density is therefore the result.
- Pad-Via via embedded in an oxide layer
- the aluminum layer thickness is typically between 600 nm and 1200 nm.
- the current flow is independent of the direction via the "pad via" and the associated oxide edge.
- the area of the planar aluminum surface is used for testing and / or as a mounting surface, for example for bond wires or for so-called solder bonds, which are used in flip-chip technology. It can also be used only as test pads. A whole-surface underlaying of the bond pad with copper is opposed by the fact that due to the mechanical stability under the area of the aluminum pads used for the connection and for testing, copper wiring is disadvantageous.
- the integrated connection arrangement according to the invention has the following features:
- the circuit arrangement according to the invention has the effect, particularly in the case of the aluminum bond pads mentioned, that there is no dielectric stage in the main current path at which the current density increases. For example, more than 50 percent of the current flows in the main current path, based on the total current flowing through the contact area. A small part of the current flows past the connection arrangement, for example, via another current path of the outer power structure.
- the reliability of the product increases due to the current density, which is no longer locally increased.
- electromigration effects are reduced.
- a barrier can be created in the main current path both in the area of contact between the inner lead structure and the outer lead structure and outside of this area on a planar surface, so that there are hardly any local defects in the barrier layer. As a result, the service life of the integrated circuit arrangement is increased considerably.
- the critical stage is avoided by removing the oxide between the outer conductive structure and the inner conductive structure in the region of the current-carrying region.
- the outer interconnect connects, in particular in a current-carrying area, in particular in an area with a particularly high current density, between the contact surface 50 and the downstream interconnect 22 in a planar manner to the inner conductive structure.
- the outer guide structure serves in one section as a guide track for lateral current transport in a metallization layer.
- the section is preferably longer than 10 nm or longer than 1 micrometer or longer than 10 micrometers or longer than 100 micrometers.
- the section increases the mechanical stability, relaxes the design and / or leads to a reduction in the number of metallization layers required if the outer metallization layer is used specifically for wiring and not only for connection.
- the inner guide structure contains a main guide body or guide core made of copper or a copper alloy, which is in contact with the contact area.
- the lead core conducts, for example, 90 percent of the current flowing through the lead structure.
- the outer guide structure remote from the substrate contains a main guide body made of aluminum or an aluminum alloy.
- the outer conductive structure at the contact area contains a barrier layer, preferably a layer made of tantalum, titanium, titanium nitride, tantalum nitride or a combination of layers of these materials.
- the barrier layer prevents copper from penetrating the aluminum and there are volume changes that favor electromigration and deteriorate the quality of the connection, for example a bond connection.
- the advanced training also combines the good bondability of aluminum with the high conductivity of copper.
- the outer guide structure is covered by a passivation layer or a passivation layer sequence in at least one edge region, but preferably along its entire edge remote from the substrate.
- Passivation layer prevents penetration, for example of moisture into the integrated circuit arrangement on the interconnect remote from the substrate.
- the outer lead structure also protrudes beyond the contact area on one side of the inner one
- the supernatant is in particular more than 10 nm (or more than 100 nm). In this way, a reservoir for material is formed which can fill up hollows created by electromigration.
- the protruding area is preferably connected to no other parts than the interconnect remote from the substrate.
- the outer guide structure has at least one edge area that lies on the insulating layer. This applies in particular to the entire edge area of the outer guide structure. This measure makes it easier to structure the external lead structure.
- the boundary surface is a flat surface.
- CMP processes Chemical Mechanical Polishing
- no metallization layer is arranged between the outer metallization layer furthest from the substrate and the next metallization layer close to the substrate, which only contains structures that conduct current in the normal direction or counter to the normal direction of the main area during operation of the integrated circuit arrangement, i.e. which only contains Via's.
- the invention relates to a method for producing an integrated circuit arrangement, msbe- special of the circuit arrangement according to the invention or one of its developments.
- the technical effects mentioned above also apply to the manufacturing process.
- the metallization layer close to the substrate is produced using a damascene technique with a final planarization step.
- the Damascene technology is particularly suitable for copper interconnects (but not exclusively).
- the outer metallization layer is produced with the deposition of a layer and subsequent structuring of the layer in a photolithographic process. This procedure is particularly suitable for the production of aluminum layers or layers containing aluminum.

Has in the embodiment the stop layer has a thickness of 50 nm. Adjacent to the stop layer 34, the metallization layer 16 contains an electrically insulating insulating layer 36 made of a different material than the stop layer, for example silicon dioxide. Above the conductive structure 22, the insulating layer 36 and the stop layer 34 are penetrated by a recess 37 with a left recess edge 38 and a right recess edge 40, so that a contact area B1 is exposed.
- only the stop layer 34 is used.

- the metallization layer 16 also contains regions of an optional electrically conductive barrier layer 42, which consists, for example, of titanium nitride and has a thickness of, for example, 50 nm. Such an area is shown in FIG. 1 in the region of the recess 37 with the recess edges 38 and 40. The area shown in FIG. 1 extends at the bottom of the cutout at the boundary surface 32, on the side walls of the cutout 37 and overlapping to the edge of the cutout 37 on the insulating layer 36. Lapping is, for example, 300 nm in each case.

- a line shows the position of the outline of the recess 37. Below the left quarter of the recess 37 is one half of the interconnect 22 arranged in the metallization layer 14. The recess 37 only partially protrudes beyond the guide structure 22, so that the guide structure 22 serves both for current transport in the vertical direction and in the lateral direction.
- Another line shows the position of the aluminum structure 44, which also lies on the insulating layer 36 along its circumference outside the recess 37.

- the overlap of the copper core 24 and the aluminum structure 44 has changed, for example the left edge 38 of the recess 37 bears against the copper core 24 or partially projects into it, in particular outside the main current path.
- the overlap of the passivation over the aluminum structure 44 can also be varied.
- An alternative position for the edge 38a of a recess 37a is indicated in FIG. 4 by an arrow 200.
