Abstract
An integrated circuit device with a light-emitting diode thereon is disclosed. The device has discrete regions which function in concert to emit light when a suitable amount of voltage is provided. The device has four discrete regions: a first doped silicon region; a second silicon dioxide region; a third organic material region; and a fourth conducting material region. The first and fourth regions are electrodes which inject holes and electrons into the conducting organic material. The second region lowers the energy barrier between the first and third regions which improves the efficiency with which the polymer emits light. The diode of the present invention is fabricated on an integrated circuit using conventional integrated circuit fabrication techniques.
