RTP System Lamps: Built for the Toughest Wafer Work
Let’s talk about RTP lamps. We built these things for the hardest jobs in advanced semiconductor wafer processing. The whole point? Give you consistent, high-density heat in a package that doesn’t eat up space. When your line is screaming along, these lamps keep pace. Every single cycle.
What’s Inside: Power, Voltage, and the Right Fit
It all comes down to tight temperature control. Most industrial RTP systems run on 400V, and that’s intentional. It keeps the current lower, which means smaller wiring, less voltage drop, and a cooler electrical connection. And the 300mm length? Not a random choice. It lines up perfectly with the standard wafer pocket and chamber, so you get even heat across the whole wafer. The power ratings are tuned to hit your ramp rates cleanly, without pushing the system too hard.
The Materials That Make It Happen
The tube is quartz. Why? Because it handles sudden temperature swings without flinching, and it transmits infrared consistently. Inside, the halogen cycle keeps the filament stable over long runs. No blackening. No drop-off. Just steady output, shift after shift. Then there’s the R7s connector. It’s a direct, bi-pin setup that locks the lamp into the reflector. You get a solid mechanical and electrical fit, which cuts down on contact resistance. When it’s time to swap a lamp, it’s a quick job—no tools needed.
Real-World Use: Where These Lamps Shine
Out on the floor, these lamps live inside rapid thermal processing chambers. They deliver fast, focused heat for annealing and thin-film work. The compact size and R7s mount make them a straight drop-in for many OEM fixtures, so changeover is fast. You get serious power density—that’s the payoff. But that heat has to go somewhere. The chamber and cooling have to be up to the task. If the cooling is too small, you’ll see drift and cycle limits creep in. We focus on delivering the heat. You focus on building the system that can manage it.
