Cassette cleaning infrared dryer

On the fab floor, a wet cassette isn’t just a bottleneck—it’s an open invitation for contamination. Leftover moisture leads to surface defects, and one watermark can torpedo yield. Conventional drying leaves thermal gradients that trap water along the edges and in the corners. You need a dryer that dries the whole load, not just the center.

Infrared heating: sub-millimeter uniformity, repeatable

We built this cassette cleaning infrared dryer around controlled NIR emission and a thermal field that’s uniform down to the sub-millimeter. The payoff is a repeatable temperature profile across the entire cassette footprint, with tight uniformity even when the load configuration changes. Photoresist bake steps—soft bake and hard bake—live and die on thermal budget stability. This system delivers that, cycle after cycle. It runs cleanroom Class 1–100 compatible, produces zero particle events during operation, and the heating profile is fully reproducible for auditable process control.

Wafer carrier cleaning dryer

Out on the 300mm line, you know the drill: a carrier comes off the wet bench and still carries microliters of trapped DI water. If you don’t pull that moisture down to a repeatable dry state, it migrates into the photoresist during soft bake. CD tolerances drift, and defects start showing up on the scanner. The wafer carrier cleaning dryer was built to stop that chain reaction at the door. What actually matters under the hood We designed the dryer around a high-purity thermal system that holds ±0.1°C wafer-level uniformity across the entire carrier. NIR elements heat fast and without contact, so moisture lifts off without thermal lag. A high-efficiency filtration path keeps particle generation at zero and keeps the chamber environment aligned with cleanroom Class 1–100. The payoff is repeatable temperature control for photoresist bake steps and a repeatable dry state, cycle after cycle. Here’s why this matters in lithography: the thermal budget isn’t optional. Soft bake and hard bake have to land inside spec to set viscosity, adhesion, and line-edge roughness the right way. When residual solvents and moisture add variability, your distributions widen and rework lots pile up. This dryer strips that variability out, so you run tighter, scrap less, and stop burning lots on rework. The platform is built for 24/7 operation with a focus on zero unplanned downtime—predictable maintenance, predictable output. A couple of practical notes. The dryer drops into existing wet-to-dry handoffs, but site utilities matter. Plan for dedicated exhaust routing and clean, dry compressed air to keep the purge path stable. In high-humidity fabs, a small upstream humidity preconditioning step can help lock in cycle time. We match the connector interface to your carrier handling standard, so installation stays straightforward and you don’t break process continuity.
