20090213369 | Metallic Nanostructures Adapted for Electromagnetic Field Enhancement - The disclosure relates to metallic nanophotonic crescent structures, or “nanocrescent SERS probes,” that enhance detectable signals to facilitate molecular detections. More particularly, the nanocrescent SERS probes of the disclosure possess specialized geometries, including an edge surrounding the opening that is capable of enhancing local electromagnetic fields. Nanosystems utilizing such structures are particularly useful in the medical field for detecting rare molecular targets, biomolecular cellular imaging, and in molecular medicine. | 08-27-2009 |
20090314929 | Biomimetic Microfabricated Compound Eyes - An artificial compound eye comprising a plurality of three-dimensional (3D) self-aligned polymer microlenses disposed on a curvilinear surface; and a plurality of waveguides, wherein each of the waveguides is in optical communication with one of the plurality of polymer microlenses. | 12-24-2009 |
20120013967 | ELASTOMERIC DEVICE FOR TUNABLE IMAGING - An optical micro-electro-mechanical systems (MEMS) structure is provided. The structure includes an elastomer membrane, a plurality of polymer fibers attached to the elastomer membrane, an array of detectors operatively connected to the plurality of polymer fibers at a first end of the plurality of polymer fibers, and a microlens array operatively connected to the plurality of polymer fibers at a second end of the plurality of polymer fibers. A method of manufacturing an optical MEMS structure is provided. The method includes forming a hollow PDMS chamber in which PDMS fibers extend from top to bottom using a lost wax molding process. | 01-19-2012 |

20110248317 | SEMICONDUCTOR DEVICE AND METHOD OF FABRICATING THE SAME - Provided are a semiconductor device and a method of fabricating the same. The semiconductor device includes lateral and upper hydrogen blocking patterns disposed to prevent hydrogen from diffusing into the cell array region. Accordingly, hydrogen is effectively prevented from being trapped in a tunnel dielectric, thereby improving the reliability of the semiconductor device. In the method, when a cell array contact plug is formed, a lateral hydrogen blocking pattern and an upper hydrogen blocking pattern are formed at the same time. Thus, an additional process for forming a hydrogen blocking pattern is unnecessary, thereby simplifying a process. | 10-13-2011 |
