20140144874 | SYSTEM AND METHOD FOR SELECTIVELY REMOVING ATOMS AND USES THEREOF - Embodiments of the present disclosure provide a method for selective removal of atoms from a substrate. Such a method comprises forming a patterned mask over at least a portion of the surface of the substrate to form a masked portion and an unmasked portion of the surface. In an embodiment, the method comprises exposing the surface to low energy light ions. In a related embodiment the low energy light ions selectively remove atoms from the unmasked portion of the substrate. In some embodiments, the method further comprises removing the mask. | 05-29-2014 |
20150194261 | Systems and Methods for Locally Reducing Oxides - In the systems and methods for synthesizing a thin film with desired properties (e.g. magnetic, conductivity, photocatalyst, etc.), a metal oxide film may be deposited on a substrate. The metal oxide film may be achieved utilizing any suitable method. A reducing agent may be deposited before, after or both before and after the metal oxide layer. Oxygen may be removed or liberated from the deposited metal oxide film by low temperature local or global annealing. As a result of the annealing to remove oxygen, one or more portions of the metal oxide may be transformed into materials with desired properties. As a nonlimiting example, a metal oxide film may be treated to provide a magnetic multilayer film that is suitable for bit patterned media. | 07-09-2015 |

20100001917 | PLANAR DIELECTRIC WAVEGUIDE WITH METAL GRID FOR ANTENNA APPLICATIONS - A waveguide includes a dielectric substrate having first and second opposed surfaces defining a longitudinal wave propagation path therebetween; and a conductive grid on the first surface of the substrate and comprising a plurality of substantially parallel metal strips, each defining an axis. The grid renders the first surface of the substrate opaque to a longitudinal electromagnetic wave propagating along the longitudinal wave propagation path and polarized in a direction substantially parallel to the axes of the strips. The grid allows the first surface of the substrate to be transparent to a transverse electromagnetic wave having a transverse propagation path that intersects the first and second surfaces of the substrate and having a polarization in a direction substantially normal to the plurality of metal strips. A diffraction grating on the second surface allows the waveguide to function as an antenna element that may be employed in a beam-steering antenna system. | 01-07-2010 |

20090121804 | MONOLITHIC SEMICONDUCTOR MICROWAVE SWITCH ARRAY - A microwave switch array includes a plurality of microwave slotlines, each of which is controlled by a semiconductor switch including a first PIN junction formed by a primary P-type electrode and a primary N-type electrode separated by the slotline. The switches inject a plasma into the slotline in response to a potential applied across the first PIN junction. Each of the switches includes a second PIN junction between the primary P-type electrode and a secondary N-type electrode, and a third PIN junction between the primary N-type electrode and a secondary P-type electrode. Metal contacts connect the primary P-type electrode and the secondary N-type electrode across second PIN junction, and the primary N-type electrode and the secondary P-type electrode across the third PIN junction. The secondary electrodes extract plasma that diffuses away from the first PIN junction, thereby minimizing the performance degrading effects of plasma diffusion. | 05-14-2009 |
