Abstract
PURPOSE:To prevent the production of faulty devices and to manufacture the device of improved quality by a method wherein a photoreceiving device of the In1-xGaxAs1-yPy family topped with an InP layer is provided with an In1-uGau As1-rPr serving as diffusion mask and junction layer. CONSTITUTION:Piled one upon another on an InP substrate 14 and an In1-xGax As1-yPy photoabsorbing layer 13, a low concentration InP layer 12, and high concentration InP window-and-multiplier layer 11 meeting the conditions 0<x<= 0.47, 0<y<=1, and x=0.47(1-y). Next, an In1-uGauAS1-rPr layer 15 [u=0.47(1-r), 0<u<=0.47, 0<r<=1], which is patterned by an SiO2 mask. Then the mask is removed and Cd is thermally diffused to form a photoreceiving section 18 and a guard ring 17. A mask is again placed on the photoreceiving section 18 and the InP layer 11 is etched away using a part of the guard ring 17. Then evaporated AuZn is deposited on the film 15 surrounding the photoreceiving section 18 thereby creating an alloy layer out of which electrodes 19 are selectively formed. This eliminates heat caused distortion and penetrating electrodes as causes for fualty products and photoreceiving devices can be realized with their component parts superior as regards withstand voltage, amplification, and dark current.
