A CMOS isolation process using a dry liftoff is proposed in which a sputter-deposited SiO2 film is delineated by removing the Mo pattern underneath the SiO2 film making use of the sublimation of the molybdenum oxide. Test CMOS transistors were fabricated. No significant differences were observed in the characteristics of transistors fabricated by dry- and conventional wet-liftoff techniques.
