Abstract: A high-temperature superconductive microwave delay line that operates in an essentially pure TEM field configuration in a compact assembly. The delay line is a planar signal delay line which includes first and second substrates made of first and second dielectric materials; each substrate can be LAO material. First and second patterned delay line segments having a configuration, are formed of first and second conductive materials on the obverse sides of the first and second substrates, respectively. On the reverse side of each of the first and second substrates, respective first and second ground planes are formed using respective first and second conductive materials, which are preferred to be high-temperature superconductive films, such as YBCO films. The delay line also includes coupling means for coupling the first patterned delay line segment to the second patterned delay line segment, thus bringing the two patterned delay line segments into substantial contact.

Abstract: An apparatus is disclosed for providing an electrostatically actuated mechanical switch utilizing a cantilever beam element fabricated by solid-state microfabrication techniques. The apparatus reduces the required pull down voltage and lowers the switch inductance by separating the pull down electrode and contact pad. The pull down electrode is placed further away from the fulcrum of the cantilever beam then the contact pad to optimize the mechanical advantages which allow for a reduced pull down voltage. The contact pad is placed closer to the cantilever fulcrum to reduce the associated switch inductance. The gap between the contact pad and the cantilever beam is less then the gap between the pull down electrode and the cantilever beam to insure that the cantilever makes first contact with the contact pad.

Abstract: A semiconductor device has material removed from the back of the substrate and a manufacturing process is provided for manufacturing these devices. In the exemplary embodiment, a GaAs FET chip is formed by a process including the step of etching the GaAs substrate from the back of the chip in a defined removal region to reduce the dielectric constant in the region of the source-to-drain path. A buffer layer of differing material provided between the active layers and the substrate prevents etching of the active layers during the removal process. To allow simplified etching patterns, the source-to-drain path may be laid out on the surface of the chip in a variety of patterns, including "packed" patterns concentrating a large path area in a small surface area of the chip. Optionally, this buffer layer may also be etched away in a further processing step.

Abstract: A high speed optical sensor comprising a parallel array of vertical field effect transistors and optical fibers disposed in the recesses between the transistors is disclosed herein. Each of the vertical field effect transistors includes a substrate of doped gallium arsenide divided by a depleted region. One side of each of the gallium arsenide substrates is flanked by an optical fiber which transmits an optical signal into one side of the depleted region, while the other side of the substrate includes a gate electrode for controlling the flow of photo charges induced in the depleted region by the light signals. The gate electrode serves not only to control the flow of charges through the transistor but also reflects back a portion of the light emanated by the optical fiber so that it passes a second time through the depleted region.
