Vacuum-Compatible Infrared Heaters: The Real Deal Behind High-End Wafer Lines
We built these vacuum-compatible infrared heaters for one reason: to tough it out in the brutal environment of advanced semiconductor processing. And to deliver heat that’s consistent, high-density, and exactly where you need it. We’ve run our units head-to-head against the big international brands, right there on actual wafer lines. The numbers speak for themselves.
Let’s Talk Power, Voltage, and Size
The core is a 300mm quartz tube. It’s sized to drop right into standard tools, so you don’t have to rework your whole setup. The 400V input isn’t just a random choice. It’s what lets us push serious current through a compact design, giving you the watt density you need for a lightning-fast thermal response. The 2500W rating means you get rapid ramp-up and rock-solid holding temperatures, even under vacuum. But here’s the catch: your chamber’s cooling needs to be up to the task. If your heat exchanger isn’t sized right, you’ll feel that extra heat in the room.
Inside the Design: The Details That Matter
Inside the tube, the halogen cycle keeps the filament stable. So it resists burnout, even after thousands of thermal cycles. The quartz envelope is chosen specifically for its high transmission in the shortwave infrared band. That means direct, line-of-sight heating with almost no extra mass. A protective coating keeps contamination and outgassing at bay under vacuum, so your chamber stays clean. And the R7s connector? It’s just a smart, practical choice. It locks in place, handles the current, and makes swapping out the lamp a simple, drop-in job.
What This Means for Your Wafer Line
On a high-end wafer line, your heater needs to deliver precise, localized heat without adding particles or causing process drift. Our vacuum-compatible infrared unit does exactly that. It focuses the energy right where you want it, cuts down cycle times, and means less time spent on maintenance. It’s built for the rigors of the cleanroom, where reliability is all about uptime and yield. If you want to see what it can do, we’ll put our heater on your line. Let the data do the talking.
