Abstract :
n and p-type nanocrystalline thin film transistors in coplanar top gate configuration have been processed at low temperature. All silicon layers (intrinsic, n and p-type) have been deposited by hot-wire chemical vapor deposition on glass substrates covered with SiO2. Gate insulation has been achieved by means of high quality sputtered SiO2. The maximum temperature reached during the whole process was 200°C. Very high field effect mobility has been obtained for both kinds of devices, with values of 22 cm V-1s-1 for the electron mobility and around 1.0 cm V-1s-1 for the hole mobility.
