  • Patent number: 11894276
    Abstract: A method includes providing a structure having a first channel member and a second channel member over a substrate. The first channel member is located in a first region of the structure and the second channel member is located in a second region of the structure. The method also includes forming a first oxide layer over the first channel member and a second oxide layer over the second channel member, forming a first dielectric layer over the first oxide layer and a second dielectric layer over the second oxide layer, and forming a capping layer over the second dielectric layer but not over the first dielectric layer. The method further includes performing an annealing process to increase a thickness of the second oxide layer under the capping layer.

  • Patent number: 6331438
    Abstract: Optical sensor, probe and array devices for detecting chemical biological, and physical analytes. The devices include an analyte-sensitive layer optically coupled to a thin film electroluminescent layer which activates the analyte-sensitive layer to provide an optical response. The optical response varies depending upon the presence of an analyte and is detected by a photodetector and analyzed to determine the properties of the analyte.
