Notes:
Etching of SiO2 with low-energy Ar ions has been studied in an electron cyclotron resonance (ECR) based etching system. Ion energies were controlled by a capacitively coupled 13.56 MHz bias of the substrate. Etch rates of over 100 A(ring)/min have been achieved at ion energies below 100 V. The variation in etch rate has been studied as a function of ECR power, self-induced bias, and position of the wafer relative to the ECR source. This low-energy process can be utilized for cleaning of semiconductor surfaces prior to chemical vapor deposition or metallization processes.
