Abstract
An improved image sensor is described. The sensor includes a photosensitive semiconductor device comprises a glass substrate, a light blocking electrode formed on the glass substrate, a photosensitive semiconductor film formed on the electrode, a transparent electrode. A light window is opened through the semiconductor device. On the light path including the light window, an uneven interface is formed in order that light rays incident on the sensor is modified and reachs the photosensitive semiconductor after reflection on an original.
