Ewelina N. Lucow 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).

  • Method for etching multi-layer epitaxial material
    Patent number: 9263611
    Abstract: A single-step wet etch process is provided to isolate multijunction solar cells on semiconductor substrates, wherein the wet etch chemistry removes semiconductor materials nonselectively without a major difference in etch rate between different heteroepitaxial layers. The solar cells thus formed comprise multiple heterogeneous semiconductor layers epitaxially grown on the semiconductor substrate.
    Type: Grant
    Filed: November 16, 2012
    Date of Patent: February 16, 2016
    Assignee: Solar Junction Corporation
    Inventors: Onur Fidaner, Michael West Wiemer, Vijit A. Sabnis, Ewelina N. Lucow
  • Method for making semiconductor light detection devices
    Patent number: 8912617
    Abstract: A semiconductor light detection device fabrication technique is provided in which the cap etch and anti-reflection coating steps are performed in a single, self-aligned lithography module.
    Type: Grant
