Compact infrared dryer for IC

On the fab floor, you know the drill: a photoresist bake that drifts even 0.2°C can pull critical dimension control off-spec and eat into yield. You need a thermal step that repeats, hour after hour, without adding particles or unplanned downtime. What matters technically We built this compact infrared dryer for IC around short-wave emitters and quartz optics. The result is rapid, direct-coupled heating with tight thermal uniformity. Across the wafer, temperature control holds ±0.1°C, and soft bake and hard bake photoresist profiles stay stable run-to-run. The footprint fits tight bays, yet the output keeps pace with the thermal budget of larger ovens. It runs on standard voltage, integrates with existing handlers, and meets cleanroom Class 1–100 constraints without generating particles. Repeatability isn’t marketing—it’s specified: 5,000+ hours with less than 5% output drift. Why it works where it matters In lithography and post-process drying, time and temperature are a pair—you can’t move one without affecting the other. This unit cuts cycle time by heating on demand, while keeping the process window intact so CD and overlay stay protected. Energy use drops because the energy goes into the film, not the chamber. That translates to stable line yield, fewer scrap lots, and maintenance intervals you can plan around. The design is a drop-in alternative to mainstream thermal modules and aligns with international semiconductor equipment practices. Things to keep in mind Installation is straightforward, but confirm line voltage and connector compatibility before integration. Emitter window surface temperatures need safe clearance and proper guarding, especially on manual stations. Plan a short qualification run to map your exact film stack and nail the bake curve. Then lock it into the recipe so execution stays consistent, shift after shift.

Short wave infrared lamp for IC

On the fab floor, you learn fast: a 0.1°C drift in bake temperature can shift a critical dimension by nanometers and wipe out hours of lithography work. When you’re running photoresist processing—soft bake, hard bake, post-exposure bake—wafer-level thermal uniformity isn’t a “nice to have.” It’s the gate on yield. Here’s what we lean on. Our short wave infrared (SWIR) lamps put heat directly into the stack, fast, and keep uniformity across the wafer within ±0.1°C. The quartz envelope and reflector geometry hold the thermal profile steady, and the lamp output stays repeatable cycle after cycle. Cleanroom behavior is built in, not bolted on. We use low-outgassing materials, sealed terminations, and a design that doesn’t shed particles—so Class 1–100 environments stay in spec. And the system runs 24/7 on predictable maintenance, not surprise downtime. SWIR energy gets absorbed efficiently by photoresist and substrates, which shortens bake time and lowers the thermal budget. Tighter temperature control means solvent removal is consistent during soft bake, and glass transition behavior is repeatable during hard bake. That translates to fewer defects and better critical dimension control. You get faster throughput without giving up repeatability, and lower energy draw without compromising precision. The payoff is fewer rework lots, tighter process windows, and yield that stays put. A few practical notes before you spec it in. Installation has to match the lamp footprint, voltage, and connector type to your existing thermal module. If the reflector or thermal mass is off, the uniformity profile drifts. The quartz envelope is tough, but it needs careful handling during replacement. A scratch can create a hot spot you’ll pay for later. Plan routine calibration to hold that ±0.1°C spec over thousands of bake cycles.
