Aluminum reflector for IR lamp

On the lithography floor, you know the drill. A 1°C swing during the photoresist bake is enough to scrap an entire lot. Thermal control has to act like a setpoint, not a wild card. That’s why we built the aluminum IR reflector for semiconductor-grade heating, where yield lives and dies on repeatability. What matters, technically We tune the reflector geometry and surface finish to hit ±0.1°C uniformity across the wafer, so your thermal budget stays stable through soft bake and hard bake. It’s cleanroom-compatible for Class 1–100, and the particle-controlled design keeps contamination out of the chamber. The material and coating strategy keep outgassing low and reflectance steady over thousands of hours, so lamp output doesn’t drift and thermal repeatability stays solid. Here’s what that means on the line. You get tighter critical dimension control, fewer reworks, and bake profiles that stay consistent shift after shift. You can run with confidence because the system holds up 24/7, cutting unplanned downtime. Plus, the reflector maximizes IR coupling into the photoresist, so you lower the thermal load on the module and trim operating costs—without giving up temperature stability. A few practical notes. The reflector has to be aligned within tight tolerances to the lamp axis; if it’s off, the hot zone shifts and uniformity falls apart. Expect a short ramp-up after install to reach thermal equilibrium, and plan periodic checks on reflectance and cleanliness to keep performance where it should be. When it’s specified and installed right, the bake stays on the wafer, not on the hardware.
