Abstract
The semiconductor device according to the present invention comprises at least one first semiconductor circuit 2 in which first currents (Ihνa1 to Ihνa4) excited by external light (hν) are produced. It further comprises at least one second semiconductor circuit (3) which is electrically connected to the first semiconductor circuit (2) and in which second currents (Ihνb1 to Ihνb4) excited based on the external light (hν) and canceling a part or all of the voltage fluctuation produced by the current increment of the first currents (Ihνa1 to Ihνa4) when the external light (hν) shines are produced.
