Keeping Your Class 100 Cleanroom Actually Clean

If you’re running a Class 100 cleanroom, you already know that air filters are only half the battle. The real nightmare? The stuff your own equipment sheds. Most heating lamps are a liability. They flake, they outgas, and they leave behind tiny bits of debris right when you can’t afford them. We decided to fix that by pairing high-purity synthetic quartz envelopes with carbon fiber heating elements. Here is why that actually matters.

Getting the Heat Right for CNT Growth

When you’re growing carbon nanotubes, it’s easy to get obsessed with raw wattage. But here’s the thing: it doesn’t matter how much power you’re pumping into the system if that energy never actually hits the wafer. You don’t need more power; you need a better way to aim it. That’s why we use gold-coated reflectors. It’s all about stopping the waste.

Why Gold?

If you’re using standard quartz heaters, you’re probably losing a ton of energy to the chamber walls. It’s basically like trying to heat a room with an open window. We swapped that out for high-purity gold coatings on the housing. Why? Because gold is incredible at bouncing infrared radiation back where it belongs. It beats out aluminum or polished steel every time. Instead of heating up the entire vacuum chamber, the photons get shoved right back toward the wafer. It makes the energy focus much tighter. Plus, your cooling water system doesn’t have to work nearly as hard, and you’ll notice you hit those growth temperatures a lot faster.
