Abstract:
1. A light sensor comprising: a first light receiving element having sensitivity to ultraviolet light, the first light receiving element being formed on a silicon semiconductor layer of an SOI substrate provided with a silicon substrate, an insulating film formed on the silicon substrate, and the silicon semiconductor layer formed on the insulating film; a second light receiving element having sensitivity to visible light or infrared light, the second light receiving element being formed on the silicon substrate along the surface direction of a main face of the SOI substrate in a second region that is adjacent to a first region where the first light receiving element is formed; and a third light receiving element having sensitivity to visible light or infrared light, the third light receiving element being formed on the silicon substrate along the surface direction in a third region that is adjacent to the first region formed with the first light receiving element and that is separated by a predetermined separation distance from the second region.
