ABSTRACT:
An improved light activated thyristor and a method of fabricating the thyristor are disclosed. The thyristor includes a space charge zone extenable to one end surface of the thyristor body whereby the thyristor may be triggered efficiently with low power light beams. In one embodiment of the device, a notch is formed in an end surface of the thyristor body extending into the space charge region of the forward blocking pn-junction. In another embodiment of the device, a portion of the anodic base region of the thyristor is led up through the cathodic base region to the end surface of the thyristor, whereby the forward blocking junction extends to the end surface of the device.
