Title: Semiconductor device
Inventor: HORI YOSHIKAZU
IPC: H01L31/10
Filed: 1985-02-20
Abstract: PURPOSE:To obtain an element characterized by high speed operation and few noises, by providing a low resistance layer at the lower part of a light receiving element, enhancing the mobility of carriers, providing an InP layer, whose conducting type is the same as that of a channel, at the lower part of an FET, thereby preventing the reaching of a depletion layer to a semi- insulating substrate. CONSTITUTION:A low resistance n<+> layer 2 is formed at a part corresponding to the lower part of a photodiode 20 in a semi-insulting InP substrate 21. Then, on the layer 2 and the substrate 21, an n<-> type InP (or InGaAsP having the composition close to this) layer 3 is formed. On the layer 3, an In0.53Ga0.47As (or InGaAsP having the composition close to this) layer 4 is formed. Then, Zn is implanted or diffused in a light receiving part 6 of the light receiving element 20 and a gate part 5 of an FET 30. Thus, a (p) region is obtained. Then the mobility of light carriers yielded in the light receiving element 20 becomes quick, and a high speed is obtained. Since the reaching of the depletion layer of the FET 30 to the substrate 21 can be prevented, impact ion currents are not generated, and low noise can be implanted.
