| Abstract(in English) | We have developed a capacitive fingerprint sensor using low-temperature poly-Si TFTs and succeeded to getting good results about fingerprint certifications. The chip area is 30mm×20mm and tile array area of this sensor is 20mm×15mm. High resolution of 423dpi (60μm pitch) has been realized by a nobel cell structure only with one transistor and one sensor plate. This method is able to get big dynamic range for protecting leak current in other arrays by utilizing the big threshold voltage of low-temperature poly-Si TFTs. |
