Abstract

An 8×8 carbon nanotube (CNT) sensor array integrated on top of the CMOS chip is proposed. After the chip is fabricated in standard CMOS process, the CNTs network is formed on top of each sensor cell site of the fabricated chip. When the resistance of the CNT is changed by the chemical reaction, the sensing circuit in the chip measures the charging time of the RC (CNT-Resistor & Capacitor). Finally the information of measured time is converted to a digital code. The CMOS chip was fabricated by Dongbu 0.1 Sum technology and the size of the 8×8 sensor array is 2 mm*2mm. From the electrochemical experiments, the test chip shows the feasibility of sensor for the simultaneous detection of the various chemical reactions.
