Abstract
A device for photoelectric conversion and a process for fabricating the device are provided. The device exhibits superior dark current characteristics, and therefore a superior contrast ratio. The device is arranged to reduce or eliminate the vertical component of an electric field under an area where an ohmic contact, rather than a Schottky barrier, exists. The device can be fabricated using process equipment that sputters one or more of the device layers, including the wiring metal.
