A solid-state imaging device having a scanning circuit and a photoconductive film formed in layers on a semiconductor substrate, and a process for forming the same, wherein high resolution with substantially no color mixing is attained. An electrode layer is formed over the semiconductor substrate for providing the plural electrodes, and a photoconductive film is formed over the electrode layer. A first transparent electrode is produced over the photoconductive film, after which a resist pattern is formed on the first transparent electrode layer corresponding to the pixels. The first transparent layer and the photoconductive film are etched according to the resist pattern to spatially isolate adjacent pixels in the first transparent layer and the photoconductive film. Adjacent pixels are isolated by etching, using the resist pattern, that part of the electrode layer on which are disposed the first transparent electrode layer and the photoconductive film between isolated pixels.

In a process for fabricating a static induction transistor having a gate region which is formed in a semiconductor layer including a channel region, ions of an impurity element are implanted into the semiconductor layer from the surface thereof to form the gate region. Ions of an element lighter than the impurity element are implanted into the gate region from the surface of the semiconductor layer in such a way that the concentration of the light element exhibits a plurality of profiles in the depth direction of the semiconductor layer. The semiconductor layer is annealed at a relatively low temperature after the two implanting steps to form the gate region in the semiconductor layer. A solid-state image sensor device is fabricated by using the static induction transistor as a picture cell.

A system for determining photo-chemical reaction heat evolved from a sample material irradiated with radiant energy comprises a calorimeter having a pair of sample holders connected to heat-leakage type thermo-electric elements which develop electric output signals proportionate to the amount of heat energy conducted therethrough. Both sample holders are initially irradiated with radiant energy before disposing the sample material thereon to heat the sample holders and thereby develop electric output reference signals. The amount of radiant energy being irradiated on at least one of the sample holders is then selectively adjusted to effectively compensate for any difference between the two reference signals. Then the sample material is mounted on at least one of the sample holders and both sample holders are irradiated with the adjusted radiant energy thereby enabling determination of the exothermic or endothermic heat value generated by the sample material due to the photo-chemical reaction heat evolved therefrom in accordance with the difference in the electric output signals developed by said thermo-electric elements.
