The use of distributed electron cyclotron resonance (DECR) plasma sources for plasma-based ion implantation (PBII) presents limitations in terms of plasma density, limited to the critical density, and of uniformity, due to the difficulty of achieving

We have used the existing magnetic multicusp configuration of the large volume H− source Camembert III to confine the plasma created by seven elementary multidipolar electron cyclotron resonance (ECR) sources, operating at 2.45 GHz. We varied the p

The two general specifications required for plasma-based ion implantation are low pressure large size plasmas and high voltage high current pulse generators. Due to the wide ion sheath expansion (up to a few tens of cm), large volumes of plasma are m

Plasma-based ion implantation (PBII) is a recent method to implant ions into materials for modifying surface properties. Negative high voltage pulses are applied to the substrate to extract ions from the plasma and accelerate them directly onto the s

For over a decade, our group has been working on the development of distributed electron cyclotron resonance (DECR) plasma sources. The uniform distributed plasma (UDP) is the latest outgrowth of DECR, which has proved to be a flexible concept, leadi
