On the fab floor, unplanned downtime doesn’t need a post-mortem—you see it in lost wafers and spec windows you just missed. When a PVD chamber lamp goes down, the whole thermal budget for the run is in the red. We built this PVD lamp to keep that from happening, and it runs 24/7 without cutting corners.
What matters, technically
This lamp brings fast thermal response and tight uniformity across the target, so temperature stays within ±0.1°C during the critical bake steps. The short-wave infrared profile hits temperature quickly, cutting thermal lag and letting you dial in photoresist soft bake and hard bake profiles the way you need them. Cleanroom-compatible materials and a sealed build keep particle generation at zero, so it sits comfortably in Class 1–100 environments. The long-life filament design and tough quartz envelope push service intervals into the tens of thousands of hours, with output drift under 5% after 5,000 hours.
Why it works in PVD
In PVD, substrate temperature stability directly drives deposition rate, film stress, and adhesion. This lamp keeps the thermal profile repeatable, run after run, which means less scrap and rework. You get consistent film thickness, lower energy per wafer, and fewer lamp swaps. Fast ramp-up shortens cycle time without giving up profile control, and the stable output keeps you inside tight process windows across multiple recipes.
The practical details
Installation comes down to matching the lamp base and connector to your chamber fixture, then confirming voltage and cooling compatibility. Give it a short warm-up to hit steady-state irradiance, and plan your recipe ramps around that. **Keep the coolant clean and dry, and keep line voltage stable.**Over long campaigns, schedule routine optical inspections to maintain uniformity.
