A semiconductor device includes a semiconductor layer laminate in which a plurality of semiconductor layers are laminated, the semiconductor layer laminate including a light receiving layer, the light receiving layer being grown by a metal-organic vapor phase epitaxy method, the light receiving layer having a cutoff wavelength of more than or equal to 3 μm and less than or equal to 8 μm, the semiconductor device having a dark current density of less than or equal to 1×10−1 A/cm2 when a reverse bias voltage of 60 mV is applied at a temperature of −140° C. Thereby, a semiconductor device which can receive light in a mid-infrared range and has a low dark current is provided. |
