Vacuum-Compatible Infrared Heaters: Why Wafer Fabs Keep Coming Back to Our R7s Halogen Lamps for 0.1°C Control
We built this vacuum-ready infrared heater for one simple reason: to keep temperature steady—rock steady—inside the chamber. No drift. No leaks. Just tight, repeatable control. If you run wafer processing, you already know the stakes. A fraction of a degree can change everything. Our lamps deliver the stability wafer fabs need, and they do it at a price that lets you scale without cutting corners.
Power, Voltage, and Geometry—Designed Around Your Chamber
Here’s the thing: heat has to land exactly where you want it. So we match the lamp geometry to the chamber footprint. The 300mm tube length gives you a clean heat profile across the target zone, with minimal stray warmth. We chose 400V input on purpose. It keeps current lower for the same wattage, which means less voltage drop over longer wiring runs and fewer I²R losses inside the feedthroughs. And the 2500W rating? That gives you serious heat density, so you hit setpoint fast. But there’s a trade-off. High density needs solid chamber cooling and good thermal management. If the heat sinking is too small, the control loop has to work harder, and overshoot becomes more likely.
Material and Design: Halogen, Quartz, and the R7s Advantage
The heart of it is a halogen-filled quartz tube, running shortwave infrared. Halogen chemistry keeps the filament stable over time, so the output stays consistent—even after thousands of cycles. The quartz body is vacuum-rated and handles rapid thermal shock without cracking. And the R7s connector? It’s just practical. It locks in place, carries the current safely, and makes the lamp a true drop-in replacement in standard fixtures. Wire it once, and the contact stays solid—even when there’s vibration.
Wafer Fabs Need Control. This Lamp Delivers It.
In wafer processing, what you really need is controllability. Our lamp sprints to temperature, then holds it—supporting that 0.1°C consistency across the process window. Because it’s vacuum-compatible, you can run under low-pressure conditions without stressing about outgassing or leak paths. The payoff is repeatable runs, fewer tuning iterations, and uptime you can actually rely on. When you’re spec’ing a chamber upgrade, this lamp gives you the thermal headroom and the reliability to run tougher recipes without having to back off the spec sheet.
