Plasma immersion ion implantation sheath
Web(for Ribbon on Sacrificial Template) using plasma immersion ion implantation. The experiments were also carried out on FZ silicon as a reference. Boron was implanted at energies from 10 to 15 kV and doses from 1015 to 1016 cm−2, then activated by a thermal annealing in a conventional furnace at 900 and 950 C for 30 min. Webplasma generated by Electron Cyclotron Resonance (ECR) and a negatively biased substrate in the plasma. Very high dose rate implantation can occur as ions are accelerated from the edge of the sheath towards the sub strate. This, combined with simple reactor design, allows plasma immersion ion implantation (pIlI) to be used
