Out on the fab-lab bench, the photoresist bake isn’t a “nice-to-have”—it’s the thermal gate that locks in critical dimensions. A few degrees of drift, a hotspot across the wafer, and your lithography margins vanish. We built this high-temperature fab-lab furnace to keep that gate shut, run after run. What actually matters under the hood You get wafer-level thermal uniformity of ±0.1°C across the full bake range, and setpoint stability that holds even when the load is in. The hot zone uses quartz and short-wave infrared heating, so ramps are fast and repeatable—soft bake and hard bake profiles land the same way, cycle after cycle. Cleanroom compatibility isn’t an add-on; it’s built in. The furnace meets Class 1–100 environments with low outgassing materials and a particle-controlled airflow path, so particle count doesn’t jump during thermal cycles. Repeatability isn’t a claim—it’s measured, with logged profiles that match the recipe within tight tolerance. Why this fits the fab-lab rhythm In a fab-lab flow, you need speed without giving up control. This unit heats up fast and cools down under control, trimming cycle time while protecting the photoresist thermal budget. The payoff is fewer reworks, tighter CD control, and consistent film properties from the first wafer to the hundredth. Energy use is managed with targeted insulation and efficient heating, so operating cost comes down without sacrificing temperature precision. Reliability is engineered for 24/7 operation, with components chosen for long life and predictable maintenance intervals. What to plan for up front The furnace needs dedicated power and a clean, dry exhaust. It’s compatible with SECS/GEM for integration, but plan the footprint and utility tie-ins early. Run a short qualification—matching your exact bake profile will lock in repeatability and confirm cleanroom behavior before you shift into full production.
