US 2026/0040713 A1 · SEMICONDUCTOR DEVICE, IMAGE PROCESSING APPARATUS INCLUDING THE SAME, AND OPERATING METHOD OF IMAGE PROCESSING DEVICE

Abstract

The present disclosure relates to a semiconductor device, an image processing apparatus, and a method for operating the image processing apparatus. The semiconductor device includes a first electrode layer, a charge storage layer, an active layer, a second electrode layer, and a photo-sensitive layer. The charge storage layer is disposed on the first electrode layer and the base substrate and stores charges injected by a gate voltage applied to the first electrode layer. The active layer is disposed on the charge storage layer and injects charges into the charge storage layer based on the gate voltage. The second electrode layer is in contact with a portion of the active layer to be electrically connected to the active layer. The photo-sensitive layer is disposed on the active layer and provides charge to the active layer based on an optical signal.
