Abstract:
A photodiode detector comprising: an InP substrate; an u-In.sub.0.53Ga.sub.0.47As layer grown and stacked on the InP substrate; an u-InP layer stacked on an upper portion of the u-In.sub.0.53Ga.sub.0.4-7As layer; a SiNx insulation layer stacked on an upper portion of u-InP layer; an insulation layer stacked on an upper portion of the SiNx insulation layer; a P-InP layer formed by Zn diffusing on a u-InP layer portion below an opening formed at a predetermined position between the insulation layer and the SiNx Insulation layer; a P-metal layer positioned on an upper portion of the insulation layer; and, an N-metal layer formed on a lower portion of the InP substrate together with a non-reflection layer.
