Abstract:
A photodiode comprising:a first p-type layer connected to a ground level; andan n-type layer formed as a well layer in a top of said first p-type layer, said photodiode receiving light from a top side of said first p-type layer and outputting from said n-type layer an electric charge obtained as a result of photoelectric conversion of the received light,wherein a second p-type layer is provided as a well layer in a top of said n-type layer, said second p-type layer being connected within the photodiode to said first p-type layer so as to be connected to the ground level, andwherein an electrode for outputting the electric charge from said n-type layer is provided on an n-the layer side surface and an electrode for connecting said first and second p-type layers to the ground level is provided on a surface at the top side of said first p-type layer.
