Getting More Heat onto Your Wafers (Without Wasting Power)
When you’re heating wafers on transport trolleys in a clean room, every bit of energy counts. The biggest headache? Watching your heat just… vanish. Most of the time, that infrared energy doesn’t even make it to the wafer; it just gets soaked up by the chassis. That’s why we use gold.
Why Gold?
Look, aluminum is the standard, but it’s not great. It absorbs and scatters too much energy. Gold is different. It’s incredibly efficient at bouncing near-infrared light right back where it belongs. Instead of spending your wattage heating up the trolley frame—which does absolutely nothing for your process—the gold layer kicks that radiation straight toward the target. You get a much denser heat flux, and you don’t have to crank up the power draw to get it.
Making the Heat Move
It’s all about the shape and the stuff you use. We pair high-intensity IR lamps with gold-coated parabolic or elliptical reflectors. Think of it like a spotlight. We’re squeezing that radiation into a tight beam so the wafer hits its target temperature faster. Plus, we design it specifically to kill off those annoying cold spots across the wafer.
The Catch
Here is the thing: when you focus heat that tightly, the edges of the reflector get hot. Really hot. If you try to cheat the clock by pushing the wattage too high, you’re going to stress the lamp seals. You’ve got to find a balance between your power density and how the trolley breathes. If your airflow is off, the heat builds up, the reflector can actually warp, and suddenly your focal point is gone.
Just Plug and Play
We built these to be drop-in replacements for the lines you already have. You just wire them into your current controllers and let the gold do the heavy lifting. It’s a simple way to get more heat onto the silicon without blowing your power budget.
