Title: Innovations of Joachim Hoepfner
Introduction
Joachim Hoepfner is a notable inventor based in Planegg, Germany. He has made significant contributions to the field of semiconductor technology and ferroelectric materials. With a total of 16 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a method for producing a ferroelectric layer. This method involves preparing a substrate, applying a layer of material that will be converted into the ferroelectric layer, and then changing the material into the ferroelectric layer by applying an outer electrical field aligned with the desired direction in the ferroelectric material, followed by heat treatment. By providing a first noble metal electrode on the surface before applying the material, and subsequently forming a second noble metal electrode on the ferroelectric layer, a ferroelectric storage capacitor can be created. If the substrate includes memory cells with at least one transistor for each cell and the aforementioned ferroelectric storage capacitors, a ferroelectric memory arrangement can be produced.
Another significant patent is a method for fabricating an integrated semiconductor product. This process begins with providing a semiconductor wafer that has preformed semiconductor components. The next steps include forming at least one connection, exposing it from the wafer front surface, applying a protective layer, and treating the wafer front surface through a chemical mechanical polishing (CMP) step to make the connection accessible again.
