Title: Semiconductor device
Inventor: ONDA KAZUHIKO
IPC: H01L29/778
Filed: 1994-12-05
Abstract: PURPOSE: To enable reduction in ohmic resistance in forming a non-alloy ohmic electrode, by inserting into a second semiconductor layer a third semiconductor layer forming negative conduction band discontinuity with respect to the conduction band of the second semiconductor layer. CONSTITUTION: On a semi-insulating semiconductor substrate 1, a channel layer 3 constituting a channel with accumulated electrons is provided as a first semiconductor layer. A gate barrier layer 7, a donor layer 5 and a spacer layer 4 of InAlAs layers which have smaller electron affinity than that of the channel on the surface side thereof are provided as second semiconductor layers. An insertion layer 6 forming conduction band discontinuity with respect to conduction bands of the second semiconductor layers 7, 5 is inserted as a third semiconductor layer between the second semiconductor layers 7, 5, 4. Therefore, when electrons flow from an InGaAs cap layer 8 to the InGaAs channel layer 3, the tunnel efficiency of electrons with respect to the InAlAs layer is increased. Thus, the ohmic resistance in forming a non-alloy ohmic electrode can be reduced.

Filed: 1988-11-29
Abstract: PURPOSE:To detect variation in the wavelength of a light by forming a light absorption layer in a multiple quantum well structure, and incorporating the wavelength range of a light to be detected in the absorption end. CONSTITUTION:A crystalline layer 12, a light absorption layer 13 having a multiple quantum well structure and crystalline layers 14, 15 are sequentially formed on a semiconductor substrate 11. A P-type electrode 16 is formed on the upper face of the layer 15, and an N-type electrode 17 is formed on the lower face of the substrate 11. When a light having predetermined energy is radiated thereon an electromotive force is generated in a semiconductor laminated structure. Thus, when a reverse bias is applied through the electrodes 16, 17, a photocurrent flows reversely. In this case, the absorption end of the layer 13 can be varied by the structure and the applied voltage. The absorption end region of the layer 13 can be so set by utilizing the characteristic as to include the wavelength of an incident light to be detected, and used under the condition of (the absorption end wavelength of the layer 13) = (the wavelength of the incident light). When the wavelength of the incident light is varied, the photocurrent is altered. Accordingly, the variation in the wavelength of the incident light can be detected by the alteration.

Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain an active filter which has the same transfer function with a conventional article and a less number of pins for connecting external impedance than the conventional article. SOLUTION: A current operational amplifier 1 has its inverted input terminal (-) virtually grounded and supplies a current which is equal to the input current passed through a resistance 11 from its uninverted input terminal (+) to an external capacitor 21. The current which corresponds to the output voltage of the current operational amplifier 1 flows to the resistance 12 and the same current as it is fed from the uninverted output terminal (+) of the current operational amplifier 1 back to the output terminal of the current operational amplifier 1. Further, a current having the opposite polarity from that of the uninverted output terminal (+) is outputted from the inverted output terminal (-) of the current operational amplifier 2 and flows to the parallel connection of an external resistance 17, an external capacitor 22, and a feedback resistance 16.  Consequently, the output signal of a biquad filter is obtained from the inverted input terminal (-) of the current operational amplifier 2.

IPC: H04N21/2365
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To keep constant the quality of a video for broadcasting for advertising inserted into the video of a main program in digital broadcasting. SOLUTION: An encoder 162 for broadcasting for advertising generates an advertising bit stream Sc1 by compressionencoding an advertising video signal S1 while the encoder 162 controls a generated code rate so that the occupied rate of a VBV buffer meeting the MPEG standard may become a prescribed value C or lower. After the bit stream Sc1 is stored in a bit stream storing section 164, the stream Sc1 is read out during a broadcasting period for advertising based on an advertisement selection control signal Ccm. An encoder 122 for broadcasting main program generates a main-program bit stream Sc2 by compression-encoding the video signal S1 of the main program while the encoder 122 controls the generated code rate so that the occupied rate of the VBV buffer may become a prescribed value B=A-C (where, A is the size of the VBV buffer) or smaller.  A signal switch 150 generates a bit stream Sca for digital broadcasting by selectively outputting the two kinds of bit streams Sc1 and Sc2 in accordance with the advertisement selection control signal Ccm.
