    摘要: Structures for signal distribution are produced by applying a metallic seed layer over a semiconductor body. An insulating layer is applied over the metallic seed layer and openings in the insulating layer are produced by photolithographic patterning of the insulating layer. Each opening in the insulating layer is trapezoidal in cross section such that an upper portion of the insulating layer is wider than a lower portion of the insulating layer. A conductor is selectively formed over exposed portions of the metallic seed layer. After selectively forming the conductor, the insulating layer is anisotropically etched such that portions of the insulating layer abutting sidewalls of the conductor remain. Alternatively, a second insulating layer can be formed and anisotropically etched.

    摘要: An arrangement for protecting fuses/anti-fuses on chips which serve to activate redundant circuits or chip functions includes a passivation layer (e.g., hard passivation) arranged on a fully processed chip with the exception of metal contacts of a metallization level and the fuses. The chip is provided with a redistribution layer that is electrically contact-connected to the metallization level, and to a process for protecting such fuses/anti-fuses. The invention is now based on the object of ensuring sufficient protection of fuses/anti-fuses on integrated circuits. This is achieved by virtue of the fact that a dielectric (3.1, 3.2), which covers at least the region of the fuses/anti-fuses (4) and to which the redistribution layer (2) comprising the combination of materials Cu/Ni/Au is applied, is arranged on the passivation layer (5).

    摘要: The invention, which relates to a method for fabricating metallic interconnects with copper-nickel-gold layer construction on electronic components, is based on the object of specifying a method by means of which it is possible to fabricate such metallic interconnects on different electronic components cost-effectively by means of the known and tried and tested methods which have a comprehensive corrosion protection. According to the invention, the object is achieved by virtue of the fact that the interconnects are embodied such that they are completely encapsulated by being deposited in a manner buried in a patterned dielectric layer in the lower region and being covered in the upper region by a nickel-gold layer adjoining the lower encapsulation without any gaps.

    摘要: A process produces metallic interconnects and contact surfaces on electronic components using a copper-nickel-gold layer structure. The copper core of the interconnects and contact surfaces is deposited by electroplating by means of a first resist mask made from positive resist. The copper core of the interconnects and contact surfaces is surrounded by a nickel-gold layer by means of a second resist mask. The interconnects and contact surfaces are produced by means of two resist masks arranged one on top of the other, in such a way that the copper which forms the core of the interconnect is completely surrounded by the nickel-gold layer, which extends above the copper core, and an adjoining layer that extends beneath the copper core and comprises a diffusion barrier and seed layer.

    摘要: An arrangement reduces the electrical crosstalk on a chip, in particular between adjacent conductors of the redistribution routing and/or between the redistribution routing on the first passivation on the chip and the metallization of the chip. In one aspect, the arrangement reduces the crosstalk between the redistribution wiring on a chip and its metallization and can be realized simply and independently at the front end. This is achieved by at least an additional conductor (10) being respectively arranged between adjacent conductors of the redistribution routing (1) and/or at least a second passivation (7) with a lower dielectric constant of a preferred “cold dielectric” being arranged between the redistribution routing (1) and the first passivation (2) on the active region of the chip (3).
