Abstract:
1. A method for manufacturing a semiconductor photodetector by sealing at least a light receiving surface side of a semiconductor light receiving element having high spectral sensitivity in wavelengths from at least a visible light region to infrared region with a sealing resin, comprising steps of: preparing a dispersion liquid including boride of one or more elements selected from La, Pr, Nd, Ce, Y, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo or W, ruthenium oxide or iridium oxide of micro particles whose particle diameter is not more than approximately 100 nm are dispersed therein by a solvent: preparing said sealing resin by mixing said prepared dispersion liquid with a transparent resin; sealing said semiconductor light receiving element by said prepared sealing resin; and removing said solvent in said sealing resin.
