IPC: H01L29/786
Filed: 1987-12-14
Abstract: PURPOSE:To improve the reliability entering laser light into a light-voltage transducing element through an optical waveguide which is formed on the surface of an insulating substrate and operates as one signal line. CONSTITUTION:The laser light 62 from a laser oscillator 47 enters the optical waveguide 49 of a lower glass substrate 31 from an optical waveguide pipe 46 through a diffusing lens 48 and is reflected by a light reflecting film 50 to illuminate a gate 51 through a reflection and transmission light hole 52. The light is converted into a voltage to apply a prescribed voltage to the drain electrode 59 of a transistor(TR) 32, which is turned on and off. Therefore, even if a pinhole is formed in the gate insulating film 53 of the gate 51, the short-circuit of a crossing semiconductor layer 54 and an optical path 49 through the gate 51 and film 53, and a row selection line (other signal line) which runs thereupon through a film 53 and operates electrically can be eliminated. Consequently, an interlayer short-circuit is eliminated and the reliability is improved.

CONSTITUTION:The thin film layer of a magneto-optical recording medium 16, namely, a vertical magnetizing film is film-formed through a dielectric layer 14 on a disk substrate 12, a superconductive material layer 18 is film-formed in the upper layer part of the recording medium 16, and thereafter, an outer surface is covered with a protecting film 20. Consequently, at the time of executing a recording to the recording medium, when a laser beam is projected on the superconductive material layer 18, the layer is heated to a critical temperature or above, it is made into a non- superconductive condition, and a magnetic recording is executed by a magnetic modulation when a magnetic field is impressed to such a part. At the time of reproducing, the laser beam is projected, a tracking part is heated to the critical temperature or above, the Meissner effect of a superconductive phenomenon is allowed to disappear, and a leaking magnetic flux from the disappearing part is detected by a Kerr effect. In such a way, since it is sufficient that the temporary heating of the superconductive material layer is executed at the time of recording and reproducing, the recording medium can be selected in a high range.
