Radial line slot antenna plasma

Characteristics of the surface-wave plasma generated by a radial-line slot antenna (RLSA) have been studied by both direct plasma probe measurements and numerical simulations. Some unique characteristics have been found, including excellent critical radial plasma uniformity, low electron temperature under various pressure conditions, the main plasma generation area of RLSA being limited in the ... Computational modeling study of the radial line slot ... The radial line slot antenna plasma source is a high-density microwave plasma source comprising a high electron temperature source region within the plasma skin depth from a coupling window and low electron temperature diffusion region far from the window. The plasma is typically comprised of inert gases like argon and mixtures of halogen or fluorocarbon gases for etching.

SIMS measured profiles for blanket wafer (fin top) doping are presented in Fig. 1 for both pre- and post-anneal conditions. Figure 2 is a On the Near-Field Shaping and Focusing Capability of a Radial ... the slots of the antenna. The spillover efficiency is maximiz ed during the design process. The antenna is centrally fed by a simple coaxial probe. The antenna design is validated by a prototype and measurements at 12.5 GHz. Index Terms—Near field, focusing, radial line slot array, RLSA, near-field shaping. I. INTRODUCTION Microwave power coupling in a surface wave excited plasma density plasma can form with an ion sheath layer along the antenna. Then the microwave was fed into the coaxial wave-guide from the right side of the system. Now the input microwave power could propagate easily along the negative biased antenna and surface wave excited plasma generated along the antenna inside the chamber.
