摘要
Trial production of a thin-film radio frequency identification (RFID) tag with a built-in antenna was carried out using an amorphous InGaZnO (a-InGaZnO) thin-film transistor (TFT). A rectifier circuit, RF communication circuit, and logic circuit were formed using an a-InGaZnO 11,1 Even after adding an antenna, which is the thickest part, the RFID itself had a thickness of about 1 mu m. The RFID operated with a 13.56-MHz-band reader for IC cards and near field communication (NFC) devices. These results indicate the feasibility of an RFID tag that can be adhered to objects with a variety of shapes.
