Title: GaN-BASED SEMICONDUCTOR DEVICE
Inventor: ITO JUN
IPC: H01S5/343
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To surely prevent reaction of a Ti layer with a Si substrate in advance and to improve crystallinity of a GaN-based semiconductor layer, by interposing a heat-resistant layer between the Si substrate and the Ti layer and keeping state of separation for the Si substrate from the Ti layer at a forming temperature of the GaN-based semiconductor layer. SOLUTION: An Al layer 12 formed on a Si(111) face is grown epitaxially by a general-purpose evaporation method. A TiN layer 13n and Ti layer 4 are formed by a general-purpose reactive sputtering method. Thereafter, a Ti/TiN/Al/Si sample is moved from a sputtering unit into the chamber of a MOCVD unit. The chamber is evacuated, and then the sample is heated to 650 deg.C and held for five minutes. Thereafter, a buffer layer 15 made of AlGaN is grown at a growth temperature of 350 deg.C and is heated up to 1,000 deg.C to form an n-clad layer 15 and the like in accordance with a conventional method. Crystallinity of the GaN-based semiconductor layer formed in this manner is satisfactory.

Title: Amplifier
Inventor: NAKAYAMA TAKUHIDE
IPC: H03F3/30
Filed: 1979-05-18
Abstract: PURPOSE:To reduce the offset voltage at the single-ended push-pull amplifier, by providing the current source circuit in which the current changes with the offset voltage. CONSTITUTION:The signal from the input terminal IN is output via the SEPP amplifier consisting of FETQ, transistors TRQ2, TRQ3, Q4. TRsQ5, Q6 and Q7, Q8 form respectively the current Miller circuit and also the constant current circuit, and TRsQ5, Q7 are in cascode connection between the power supplies of positive and negative polarity. Accordingly, when the offset is shifted, the collector current of TRsQ6 or Q8 changes with the offset voltage, allowing the offset voltage at about ground potential. Thus, even if a FET is used at the first stage, the offset voltage can always be at ground voltage.
