摘要:
An apparatus and method for forming an electronic device (110) including an antenna (212) coupled to circuitry (216, 218) for conducting signals in the radio frequency range and a housing (120, 300, 400, 600, 700) encasing the circuitry (216, 218) and the antenna (212). The housing (120, 300, 400, 600, 700) includes a coating material (314, 604, 704) overlying a substrate (312, 602, 702), the coating material (314, 604, 704) being substantially non-conducting and including a metal having a ten percent atomic weight of the combined non-conducting material and the metal. The housing (120, 300, 400, 600, 700) minimally attenuates signals in the radio frequency range and provides a metallic appearance to reflected light in the visible range.
摘要:
A method is provided for preventing electron emission from a sidewall (34) of a gate electrode (20) and the edge (28) of the gate electrode stack of a field emission device (10), the gate electrode (20) having a surface (24) distally disposed from an anode (40) and a side (26) proximate to emission electrodes (38). The method comprises growing dielectric material (22) over the surface (24) and side (26) of the gate electrode (20), and performing an anisotropic etch (32) normal to the surface (24) to remove the dielectric material (22) from the surface (24) and leaving at least a portion of the dielectric material (22) on the side (26) of the gate electrode (20) and edge (28) of the gate electrode stack.
摘要:
An electronic device (110, 210) includes a housing (120) encasing a component (112, 114). The housing (120) includes a region (300, 600, 800, 1000) contiguous to the component (112, 114), the region (300, 600, 800, 1000) configured to selectively switch between a metallic appearance to transparent to reveal the component (112, 114) through the region (300, 600, 800, 1000) when transparent. Metal surfaces, metal particles, or shiny particles that are incorporated into device structures may be actuated. The grain sizes of the particles can be adjusted to achieve the desired reflections. In addition, individual shutters (318, 618, 818, 1018) can be fabricated with a distribution of predisposed orientations to enhance the reflectivity.
