ESD Protection Diode Strings for IC Chips of Miniature Robot Applications
The integrated circuit (IC) chips have been used in miniature robots. To ensure the reliability of IC
chips, the electrostatic discharge (ESD) issue should be considered. Several ESD protection diode strings for IC
chips of miniature robot applications are implemented and compared in this work. According to the test results,
the diode string with P+/N-well and P-/N+ diodes has higher ESD current-handling ability and lower leakage
current. Therefore, this ESD protection diode string would be more useful for IC chips of miniature robot
