Patents by Inventor Karin Schrettlinger

Karin Schrettlinger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10361096
    Abstract: In various embodiments, a method is provided. The method includes forming a metallization layer above at least one first region of a substrate. After forming the metallization layer at least one second region of the substrate is free of the metallization layer. The method further includes forming a barrier layer above the at least one first region of the substrate and above the at least one second region of the substrate. The barrier layer in the at least one first region of the substrate directly adjoins the metallization layer. The method further includes removing the barrier layer in the at least one first region of the substrate by drive-in of the barrier layer into the metallization layer.
    Type: Grant

  • Patent number: 8865522
    Abstract: A method for connecting a semiconductor chip to a metal layer of a carrier substrate is disclosed. A semiconductor chip is provided which has a first side, a second side opposite the first side, a glass substrate bonded to the second side of the semiconductor chip and including at least one opening leaving an area of the second side of the semiconductor chip uncovered by the glass substrate, and a metallization region arranged in the opening of the glass substrate and electrically contacting the second side of the semiconductor chip. The semiconductor chip with the bonded glass substrate is brought onto a metal layer of a carrier substrate. A firm mechanical and electrical connection is formed between the metal layer of the carrier substrate and the metallization region.
