Getting Your Wafer Heat Right

When you’re working in a semiconductor environment, “clean” isn’t just a preference—it’s the whole game. That’s why we use UHP (Ultra High Purity) heater lamps. Here’s the deal: when you’re heating a silicon wafer, you want every single photon hitting that surface. Wasting power by heating up the chamber walls is just throwing money and energy away.

Why we go with gold

You’ll see some people using standard aluminum reflectors, but they soak up too much energy. We use gold-coated reflectors instead. It’s not about making the equipment look fancy. It’s about the physics of infrared light. Gold is incredible at bouncing that energy right back where it belongs—onto the wafer. Instead of your heat bleeding out into the machine frame, the gold coating keeps it focused. You get more heat on the target without having to crank up the power bill.
