Abstract
PURPOSE: To detect easily and with high sensitivity multiple light of 1.06μ and 1.32μ by providing a light-shielding layer between semiconductor junctions.
CONSTITUTION: On a substrate 11 of InP monocrystal are provided a N-type layer 12 with a composition of Ga0.08In0.92As0.80P0.20, a P-type layer 13 with the same composition as the N-type layer 12, a 3μ light-shielding layer 14 of P-type conductivity with a composition of Ga0.15In0.85As0.62P0.50, a P-type layer 15 with a composition of Ga0.22In0.78As0.50P0.50, and a N-type layer 16 with the same composition as the P-type layer 15, in this order. After exposing parts of the substrate and light-shielding layer by etching, a surface layer and electrodes 17, 18 and 19 are provided. As apparent from the spectral sensitive characteristics shown in the figure, there can be obtained a light detector which, when electrodes 17 and 18 are used, has a peak at 1.32μ as indicated by curve 21 and, when electrodes 18 and 19 are used, has a peak at 1.06μ as indicated by curve 22.
