Abstract
The present invention discloses an apparatus and an e-beam etching method for integrating an OLED and a phototransistor, in which a series-connected OLED and a phototransistor are fabricated on a substrate using an e-beam etching process and connected with an insulating e-beam photoresist. The phototransistor includes a gate, a gate insulating layer, a source, a conductive channel, and a drain, and the OLED includes a semitransparent anode, a hole transport layer, a light-emitting layer and electron transport layer, a reflective cathode, and a substrate. The present invention realizes the multi-functional integration of organic electronic devices, simultaneously having the functions of light-emitting display and light-sensing, and realizes the control of the luminous intensity of the OLED according to the intensity of external light.
