Title: Wolfgang Leiberg: Innovator in Signal Distribution Technologies
Introduction
Wolfgang Leiberg is a notable inventor based in Dresden, Germany. He has made significant contributions to the field of semiconductor technology, particularly in the area of signal distribution. With a total of 4 patents to his name, Leiberg's work has had a substantial impact on the industry.
Latest Patents
Leiberg's latest patents include a process for producing layer structures for signal distribution. This innovative process involves applying a metallic seed layer over a semiconductor body, followed by the application of an insulating layer. Openings in the insulating layer are created through photolithographic patterning, with each opening designed to be trapezoidal in cross-section. This design ensures that the upper portion of the insulating layer is wider than the lower portion. A conductor is then selectively formed over the exposed portions of the metallic seed layer, and the insulating layer is anisotropically etched to maintain portions abutting the sidewalls of the conductor.
Another significant patent by Leiberg is an arrangement and process for protecting fuses and anti-fuses on integrated circuits. This invention aims to ensure sufficient protection of fuses and anti-fuses that activate redundant circuits or chip functions. The arrangement includes a passivation layer on a fully processed chip, along with a redistribution layer that is electrically connected to the metallization level.
