  • Chromium/titanium oxide semiconductor gas sensor and method for production thereof
    Patent number: 7406856
    Abstract: A metal oxide semiconductor gas sensor and a method for production thereof. The sensor comprises a sensor-active metal oxide thin layer applied to a substrate, in contact with at least one electrode. The sensor-active metal oxide thin layer comprises a chromium/titanium oxide (CTO) layer with a thickness of about 10 nm to about 1 ?m. The chromium and titantium layers are applied over each other using thin layer technology and are subsequently tempered.
    Type: Grant
    Filed: September 2, 2002
    Date of Patent: August 5, 2008
    Assignee: Fraunhofer-Gesellschaft zur Forderung der Angewandten Forschung e.V.
