A light signal of 1mum incident to the surface of this element is photoelectrically converted to produce photocarriers in the light absorbing layer 3. A pn junction of the APD is inversely biased, and photocarriers produced are injected into the carrier multiplying layer 5 by a drift electric field. Not electrons but phonons are localized in the carrier multiplying layer 5 according to the quality of a very thin superlattice. A saturation speed is regulated by a value of interaction of Lo phonons to electrons or holes. Accordingly the saturation speed in the very thin superlattice is made larger than that in conventional thin film crystal.

Abstract: PURPOSE:To simultaneously control accurately an alignment control with a gap from the variation in the added intensity by including the light directly reflected and diffracted on the installing surface of the first diffraction grating of the first article and adding the intensity of the diffracted light of all degrees diffracted symmetrically to the incident light.

When a signal of a pitch lambda/2 produced by the reflection on the back surface of the mask 13 is integrated, an envelope which exhibits a peak at the pitch P<2>/lambda is obtained, thereby attaining a signal of the ideal conditions of the zero reflection of the back surface. When an interval Z is regulated to the maximum peak value, it can be set to P<2>/lambda, 2P<2>/lambda,.... The maximum point is obtained with the signal (a) having a peak at every P<2>/lambda as roughly regulated signal. Further, a signal (b) of a period lambda/2 is used as an ultrafinely regulated signal to finely regulate in a region G. With this configuration, the position and the gap can be set in the order of 100Angstrom  with the simple grating mark.
