Latest Patents

One of Walter Preis's latest patents is a method for manufacturing a device on a substrate. This method involves forming a layer structure on the substrate, followed by the creation of an auxiliary layer on the layer structure. A planarization layer is then formed on both the auxiliary layer and the substrate. The process includes exposing the auxiliary layer through a chemical mechanical polishing process and partially removing the auxiliary layer to create a planar surface. The chemical mechanical polishing process is characterized by a first removal rate for the planarization layer that is greater than the second removal rate for the auxiliary layer.
