  • Optical switch with multiple refractive elements pivoted into respective binary states
    Patent number: 5940552
    Abstract: An optical switch 10 has a first waveguide I arranged in a first set, 2.sup.N waveguides in a second set, and N number of successive refractive elements between ends of the waveguides and a reflector 9, wherein an output signal is coupled to any of the 2.sup.N waveguides by pivoting said refractive elements to selected binary states.

  • Method of making semiconductor devices by patterning a wafer having a non-planar surface
    Patent number: 5907791
    Abstract: In accordance with a specific deposition/etching sequence, a multi-layer metallization system is formed on the non-planar top surface of a semiconductor wafer. In an electrophoretic deposition step, a conformal uniform-thickness layer of a resist material is then formed on the top surface of the metallization system. In turn, the layer of resist material is lithographically patterned to provide an etch-mask for defining features in the underlying metallization system.
