ABSTRACT:
Disclosed is a neutral beam source used for etching a semiconductor device. The neutral beam source includes a plasma chamber having quartz provided at an outer wall thereof with an RF coil, a grid assembly, a reflective member, and an electromagnet arranged around the plasma chamber while surrounding the plasma chamber. Plasma density becomes high due to the magnetic field applied to the plasma chamber so that an amount of ion flux is increased.
