    Abstract: A channel isolation region 42 is formed over the entire width of an N-type silicon substrate 41, and photothyristors, in each of which an anode diffusion region 43, a P-gate diffusion region 44, a cathode diffusion region 45 are formed parallel to the channel isolation region 42 over almost the entire width of the N-type silicon substrate 41, are formed in a left-hand portion 40a and in a right-hand portion 40b and are wired inversely parallel. Thus, the inter-channel movement of residual holes during commutation is restrained by the channel isolation region 42, by which commutation failure is suppressed to improve a commutation characteristic. Further, an operating current large enough for controlling a load current of approx. 0.2 A is obtained although a chip is divided by the channel isolation region 42. Therefore, using this bidirectional photothyristor chip makes it possible to implement an inexpensive SSR with a main thyristor eliminated.

    Abstract: A Schottky barrier diode 44 is formed between a P-gate diffusion region 33 and an N-type silicon substrate 31 in a photothyristor on a CH1 side and a photothyristor on a CH2 side. With this arrangement, the injection of minority carriers from the P-gate diffusion region 33 to the N-type silicon substrate 31 is restrained to reduce the amount of remaining carriers, and an excessive amount of carriers remaining in the N-type silicon substrate 31 during commutation has a reduced chance of moving toward the opposite channel side, allowing the commutation characteristic to be improved. Therefore, by a combination with an LED, there can be provided a light-fired coupler for firing and controlling the load.

    Abstract: A lens frame, made from metal, retaining a light-emitting lens and a light-receiving lens is retained between a second mold and a third mold both of which are made from light-shielding resins. Anchors are formed by filling light-shielding resin for forming the third mold into fixing slots formed in an upper surface of the second mold and through holes formed in the lens frame. Since the lens frame is made from metal, thermal expansion of the lens frame is hardly caused by ambient temperature changes and self-heating. This causes little difference in the amount of change in difference between the lenses. Further, the lens frame is fixed with anchors between the second mold and the third mold. This suppresses the occurrence of sliding caused by difference in thermal expansion coefficient between the lens frame and the second and third molds.

    Abstract: Si.sub.3 N.sub.4 having high humidity resistance is used as a surface protecting insulating film covering a metal layer. At a bonding pad portion where metal layer is directly exposed, coverage is provided by anti-corrosion metal portion consisting of a titanium-tungsten alloy layer and gold layers. At a signal processing circuit portion, light intercepting structure and interconnection are provided similarly by titanium-tungsten alloy layer and gold layer. Thus humidity resistance of a photodetector element containing a circuit element is improved, and the gold layer allows direct die-bonding of a laser chip or the like. Further, since light intercepting structure and interconnection can be provided at the signal processing circuit portion simultaneously with the formation of gold layer for the bonding pad portion, the number of manufacturing steps can be reduced.
