Millennium is a high-volume surface preparation system that incorporates spray, vapor, immersion, and rapid thermal anneal (RTA) technologies. It features high productive performance with six to ten processing chambers and one or two robots. The system utilizes Semitool’s Capsule™ technology for chemical delivery and surface tension gradient dry for advanced particle control. The chamber design can accommodate immersion, spray, vapor, or RTA processing. The system can increase productivity, reduce defect density, improve process control, reduce cycle time, and reduce cost of ownership. It has various applications including oxide etch, photoresist removal, post-CMP clean, pre-photo lithography clean, post-etch residue (polymer removal), back side metals clean, GaAs etch (gate recess etch), under bump metallurgy (UBM etch), pre-diffusion (pre-epi clean), pre-epi LTO oxide removal (bevels and face), pre-deposition (pre-gate clean), hydrOzone photoresist strip (post-ash), metal lift-off, Cu back side clean and bevel etch, back side films etch, fluorOzone clean, HF vapor etch.
