摘要： The most important task in realizing a downsized and low cost THz band spectroscopic and fluoroscopic instrument is to achieve downsizing and cost reduction of oscillators used in the instrument. A metal base transistor is used for an active element of the oscillator. In order to improve the maximum oscillation frequency of the transistor to several THZ, InN having a high electron saturation velocity or a material mainly composed of InN is used for a collector layer. In order to obtain characteristics with excellent reproducibility, it is useful to insert InGaN into an interface between the collector layer and the base layer. Using the metal base transistor of the present invention makes it possible to constitute an oscillator allowing a THz band oscillation. Further, the present invention provides a spectroscopic instrument applying this oscillator to at least one of a signal source and a local oscillator.

摘要： A bipolar transistor device with a large current capacity is formed by connecting a plurality of transistor elements to each other in parallel, each transistor element having a collector layer, a base layer, and an emitter layer formed respectively in a semiconductor substrate. In the bipolar transistor device, the base layers of a plurality of the transistor elements are extended in parallel to each other and those base layers are separated from each other. In each separated base layer, a first base electrode is formed on a part of the base layer which is separated from an emitter junction with the emitter layer, and a second base electrode is formed on another portion of the base layer closer to the emitter junction than the first base electrode. To dispose the base electrodes of a plurality of the transistor elements in parallel to each other, a base wiring is connected to the first base electrodes of those elements electrically. Consequently, a ballast resistor that causes no variation in the resistance value can be connected to each of a plurality of the transistor elements.

摘要： In a semiconductor device using an emitter top heterojunction bipolar transistor having a planar shape in a ring-like shape, a structure is provided in which a base electrode is present only on an inner side of a ring-like emitter-base junction region. This allows reduction of base/collector junction capacitance per unit emitter area, whereby a semiconductor device having high power adding efficiency and high power gain suitable for a power amplifier can be realized. Further, in a multistage power amplifier including first and second amplifier circuits each having one or more of bipolar transistors, a bipolar transistor in the first amplifier circuit uses an emitter having a planar shape in a rectangular shape, and a bipolar transistor in the second amplifier circuit uses an emitter having a ring-like shape and a base electrode only on the inner side of the emitter.

摘要： The present invention provides a method of manufacturing semiconductor devices, by which InGaAs-base C-top HBTs are manufactured at low cost. Helium ions with a smaller radius are implanted into a p-type InGaAs layer (in external base regions) not covered with a lamination consisting of an undoped InGaAs spacer layer, n-type InP collector layer, n-type InGaAs cap layer, and collector electrode from a direction vertical to the surface of the external base layer or within an angle of 3 degrees off the vertical. In consequence, the p-type InGaAs in the external base regions remains p-type conductive and low resistive and the n-type InAlAs layer in the external emitter regions can be made highly resistive. By this method, InGaAs-base C-top HBTs can be fabricated on a smaller chip at low cost without increase of the number of processes.
