概述

Trias SPA is a 300mm version of plasma nitridation system. The new system can also be used for oxidation processes. The Trias SPA uses unique Slot Plane Antenna (SPA) plasma, based on the Radial Line Slot Antenna (RLSA) microwave plasma. It produces high-density plasmas at low electron temperatures to enable damage-free processes at temperatures no higher than 400C. By optimizing the slot configuration of the antenna, the plasma distribution can be adjusted to achieve excellent uniformity, which is comparable to those obtained with advanced furnace technology.
