    摘要: A Group III and V element compound semiconductor such as gallium arsenide is formed on a semiconductor wafer by so-called MOCVD. A first pair of convex portions, a second pair of convex portions and crossing portion are formed from such compound semiconductor by an etching using a predetermined etching substance so that one convex portion of each pair is opposite to the other convex portion thereof and that a same crystalline surface of the crossing portion is exposed at all points where the first pair of convex portions crosses the second pair of convex portions. A pair of input terminals and a pair of output terminals are electrically connected to each convex portion of the first pair and the second pair, respectively so as to input electric current to each convex portion of the first pair and to output voltage generated in response to a magnetic field strength in such compound semiconductor. Accordingly, the occurrence of the unbalanced voltage is prevented because of the geometrical balance of two pair convex portions and crossing portion.

    摘要: A first semiconductor layer and a second semiconductor layer are laminated on a semiconductor wafer in that order. A resist pattern having an opening is formed on the second semiconductor layer. The second semiconductor layer is etched through the opening in the formed resist pattern to expose the first semiconductor layer. A surface oxide film is formed on the exposed surface of the first semiconductor layer and then selectively etched away. Alternatively, the exposed surface of the first semiconductor layer is subjected to a separate oxidization treatment and the resulting surface oxide film is selectively removed in the subsequent etching.

    摘要: An imaging device (1) includes an all-pixel readout imaging element (2) outputting a LONG signal and a SHORT signal in one field period for each pixel line, a mixing level calculator (7) calculating for each pixel line a mixing level at which the luminance level of the LONG signal is saturated, and an offset calculator (8) calculating for each pixel line an offset that raises the luminance level of the SHORT signal to the mixing level. Level mixing means (9) generates a level mixed signal for each pixel line so as to obtain a LONG signal when the luminance level is lower than the mixing level and obtain a SHORT signal with the offset added when the luminance level is higher than the mixing level. Consequently, an image having a wide dynamic range and a high resolution can be obtained and line-to-line luminance differences in the obtained image can be suppressed.

    摘要: A silicon semiconductor substrate, on which an epitaxial layer is to be formed, is set in a reaction vessel having a heating mechanism, and a gas containing TMG and AsH.sub.3 is introduced into the reaction vessel with the substrate heated to 450.degree. C., thus forming, on the substrate, a low-temperature growth layer of amorphous or polycrystalline GaAs as a semiconductor substance having a different lattice constant from that of the substrate. Then, with the TMG removed from the introduced gas, the temperature of the semiconductor substrate is increased to 750.degree. C., to cause coagulation of atoms of the low-temperature growth layer, with a thermal treatment also being performed at this high temperature, to cause growth of island-like single crystal cores. Further, a high temperature growth process is conducted in a material gas atmosphere containing TMG, whereby a GaAs film is epitaxially grown on the semiconductor substrate surface.
