    Abstract: A double-gate field-effect transistor includes a substrate, an insulation film formed on the substrate, source, drain and channel regions formed on the insulation film from a semiconductor crystal layer, and two insulated gate electrodes electrically insulated from each other. The gate electrodes are formed opposite each other on the same principal surface as the channel region, with the channel region between the electrodes. The source, drain and channel regions are isolated from the surrounding part by a trench, forming an island. Gate insulation films are formed on the opposing side faces of the channel region exposed in the trench. The island region between the gate electrodes is given a width that is less than the length of the channel region to enhance the short channel effect suppressive property of structure.

    Abstract: In an optical information medium comprising an information recording layer having a mark train of marks and spaces, the mark train is read out by scanning it with a laser beam and detecting a light intensity change pattern of reflected laser beam. Provided that the reflected laser beam includes polarized light components which define an angle null with the mark train, a polarized light component giving nullnull0 is x0 component, and a polarized light component giving nullnull90null is y0 component, the mark train is read out utilizing at least a light intensity change of x0 component. When pits or recorded marks having a size approximate to or below the resolution limit are read out, the present invention allows high read outputs to be obtained and prevents omission of readout signals.
