Title:
PHOTOSENSITIVE DETECTOR WITH COMPOSITE DIELECTRIC GATE MOSFET AND SINGAL READING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/094233
Kind Code:
A1
Abstract:
A photosensitive detector with a composite dielectric gate MOSFET is provided. The MOSFET comprises a P-type substrate (11); a source (2a) and a drain (2b) formed in the substrate (11); an underlying dielectric layer (5), a photo-electron storage layer (8), a top dielectric layer (6), and a control gate (7) stacked on the substrate (11) in sequence; wherein, the top dielectric layer (6) can prevent the photoelectrons stored in the photo-electron storage layer (8) from leaking into the control gate (7); a transparent or semi-transparent window for detecting light is formed on at least one of the substrate (11) and the control gate (7); when the photoelectrons are generated and injected into the photo-electron storage layer (8), the source (2a) and the drain (2b) are floating. A method for reading stored information is also provided.
