Unaxis Wafer Processing has launched two production tools, the Versaline and the LLS EVO II. Built on a decade of dry etching system experience, Versaline is a modular system that enables etching and deposition technologies. Its ICP, RIE, PECVD and PVD modules provide solutions for applications such as LEDs, HBTs, HEMTs and MEMS. LLS EVO II is a batch sputtering system, with five sources, each configurable for sputtering options including DC, RF, RF/DC, pulsed DC, and co-sputtering.
