  • Publication number: 20200266300
    Abstract: A semiconductor device includes a semiconductor film, an interlayer insulating film, a source-drain electrode, and a semiconductor auxiliary film. The semiconductor film includes an oxide semiconductor material and has a channel region and a low-resistance region. The low-resistance region has an electric resistance lower than an electric resistance of the channel region. The interlayer insulating film covers the semiconductor film and has a through-hole opposed to the low-resistance region. The source-drain electrode includes a source electrode and a drain electrode and is electrically coupled to the semiconductor film through the through-hole. The semiconductor auxiliary film is in contact with the low-resistance region of the semiconductor film, reduces an electric resistance of the semiconductor film, and has a first opening at least on a part of a portion opposed to the through-hole.

  • Patent number: 10615497
    Abstract: An object of the present invention is to vary the directivity of an antenna (100a) while reducing the signal loss by switching circuits (5a-5d) in a splitter circuit. The switching circuits (5a-5d) in the splitter circuit connect or disconnect n (n is an integer of 2 or more) second lines (12a) connected in parallel with a first line (10a) to/from output terminals (7) connected to n antenna elements (8) having different directivities of signals. If m (m is an integer ranging from 1 to n?1) switching circuits (5b, 5d) arbitrarily selected from the n switching circuits (5a-5d) are switched to on-states, the characteristic impedance of each of the n second lines (12a) is set to a product between the characteristic impedance of the first line (10a) and the number m of switching circuits (5b and 5d) switched to on-states.
