    • The present invention realizes a Doppler velocity detecting technique capable of performing velocity detection and analysis with a suppressed error while excellently distinguishing a clutter signal, and provides an ultrasonographic device using the technique. In a Doppler velocity detection device comprising means for transmitting/receiving pulse waves to/from a subject a plurality of times, and velocity analyzing means for analyzing a velocity of a moving reflector in the subject on the basis of a reception echo signal, the velocity analyzing means obtains a complex expansion coefficient by linearly connecting an expansion coefficient of an even-numbered degree term and an expansion coefficient of an odd-numbered degree term which is different from the even-numbered degree term by one degree, derived when reception echo time-series signals obtained by arranging reception echo signals of equal lapse time from pulse transmission times in order of the transmission times are expanded as components of a Legendre polynomial starting from the 0th degree, by using an imaginary unit as a coefficient, and obtains a signed velocity signal of a moving reflector in the subject on the basis of-the ratio between the magnitude of each complex expansion coefficient and the magnitude of an interval between the complex expansion coefficients.

    • A semiconductor device includes a heterojunction semiconductor region 9, which forms a heterojunction with a drain region 2. The heterojunction semiconductor region 9 is connected to a source electrode 7, and has a band gap different from a band gap of a semiconductor substrate constituting the drain region 2. It is possible to set the size of an energy barrier against conduction electrons, which is formed between the drain region 2 and the heterojunction semiconductor region 9, into a desired size by changing the conductivity type or the impurity density of the heterojunction semiconductor region 9. This is a characteristic not found in a Schottky junction, in which the size of the energy barrier is inherently determined by a work function of a metal material. It is easy to achieve optimal design of a passive element in response to a withstand voltage system of a MOSFET as a switching element. It is also possible to suppress diffusion potential in a reverse conduction mode and to improve a degree of integration per unit area. As a result, it is possible to reduce the size of elements and to simplify manufacturing processes thereof.
