Title: The Innovative Contributions of Ernst Christl
Introduction
Ernst Christl is a notable inventor based in Vilsbiburg, Germany. He has made significant contributions to the field of electronic component encapsulation, holding 2 patents that showcase his innovative methods.
Latest Patents
One of his latest patents is a method for hermetically encapsulating a component. This method involves producing a hermetic encapsulation for an electronic component, which may be optical and at least partially light-permeable. The process includes attaching and electrically contacting a chip-based component to a carrier with electrical connection surfaces. The front of the chip, which bears component structures, is arranged to clear the carrier. The back of the chip is covered with a synthetic material film, with edges overlapping the chip. The film and carrier are tightly bonded around the chip's edge region, and the film is structured for removal around this region. Finally, a hermetically sealing layer is applied over the film, ensuring a hermetic termination with the carrier outside the edge region.
Another patent by Christl focuses on the hermetic encapsulation of a component that includes a chip with component structures applied on a substrate in a flip-chip construction. In this method, a material is applied to the lower edge of the chip and regions of the substrate abutting the chip. A first continuous metal layer is then applied to the back side of the chip and the material, as well as on edge regions of the substrate. Subsequently, a second sealing metal layer is applied using a solvent-free process on the regions of the first metal layer that cover the material.
