What it is
The Mattson Helios is a rapid thermal processing (RTP) system designed for 8 inch wafers.[1]
How it works
General reference — not yet source-verifiedRTP systems use high-intensity lamps or laser arrays to radiatively heat a wafer from one or both sides. The wafer is held on a quartz or silicon-carbide support and the chamber is typically cold-walled to minimize heat loss.
Temperature is measured by an optical pyrometer or thermocouple and controlled via a closed-loop system that adjusts lamp power in real time. The process chamber is purged with inert gas to prevent oxidation during high-temperature steps.
Where it fits in the process flow
General reference — not yet source-verifiedIn a semiconductor fabrication flow, RTP systems fill the gap between batch furnaces and single-wafer high-temperature steps, offering tighter thermal budgets and shorter cycle times for advanced nodes. Upstream processes are typically deposition or etch steps; downstream steps include metrology or further deposition.
Applications
General reference — not yet source-verifiedOther applications include film densification, substrate cleaning, and thermal stress testing of engineered substrates. The tool supports processes for silicon, silicon-on-insulator, and III-V compound semiconductor wafers.

Frequently asked questions
What is the primary difference between rapid thermal processing and traditional furnace annealing?General reference — not yet source-verified
Rapid thermal processing heats individual wafers with very fast ramp rates and short process times, typically seconds, whereas furnace annealing processes batches of wafers with slower ramp rates and longer durations. RTP provides tighter control of thermal budget, allowing precise material modifications with minimal diffusion or side effects.
What are the typical ambient gases used in RTP and why?General reference — not yet source-verified
RTP chambers often use inert gases such as nitrogen or argon to prevent unwanted reactions during annealing. For oxidation or nitridation, oxygen or ammonia can be introduced. Process-specific mixtures are tailored to achieve the desired chemical reactions at high temperatures while controlling the environment.
Why is rapid thermal processing preferred for advanced nodes?General reference — not yet source-verified
Advanced nodes require extremely tight thermal budgets to preserve shallow junctions and precise dopant profiles. RTP's fast temperature ramps and short process times minimize diffusion, making it suitable for high-performance devices at smaller technology nodes where conventional furnaces would cause excessive thermal exposure.
