Abstract

A solid state image pickup device comprising a semiconductor substrate provided with light detecting sections and a scanning circuit for sequentially selecting the signals detected by the light detecting sections, wherein each light detecting section contains a silicon layer in which microcrystalline silicon and amorphous silicon are uniformly distributed and the crystal structure varies substantially continuously throughout. The light detecting section may further contain a hydrogenated amorphous silicon layer containing 6 to 37 atomic % of nitrogen, which is positioned on the silicon layer defined above. The light detecting section is connected with electrodes, one of which is transparent.
