Abstract

The direct sputtering of hafnium in oxygen was investigated for preparation of interface bonding structure of hafnium oxide. The starting material for the metal-insulator-semiconductor (MIS) capacitor fabrication is 100 n-type Si substrate with a resistivity in the range of 5-10 Ωcm. The ratio of oxygen and argon was 2:30 and remained unchanged during the sputtering. The results show that hafnium oxide/Si interface is thermally unstable, after thermal treatment at a temperature greater than 400°C.
