Stop Letting Your Heating Elements Ruin Your Wafers
If you’re running a Class 100 cleanroom, you already know the nightmare. One tiny flake of material—something you can’t even see—lands on a wafer, and suddenly an entire batch is trash. It’s frustrating, it’s expensive, and it usually comes down to outgassing or shedding from your heating elements. We decided to fix that by using high-purity synthetic quartz for our IR lamps. Why the quartz actually matters Here’s the thing: standard glass or cheap quartz just can’t handle the heat of a semiconductor environment. When things get hot, those impurities break down. You’ll see the lamp “smoke” or start shedding particles right when you’re ramping up. Our fused silica is different. We keep the metallic impurities incredibly low so the lamp stays clean. Plus, it’s chemically inert. It doesn’t care what process gases you’re pumping into your tool; it just doesn’t react. Getting the heat exactly where it needs to go You need the wafer hot, and you need it fast. But you don’t want to heat the air around it. Our lamps use short-wave radiation. It hits the wafer surface directly. This is a big deal because it cuts down on those convection currents that stir up floor dust and send particles flying toward your product. You can spec these to fit your specific wattage and voltage. If you go for high-wattage density, you save a lot of space in the chamber. Just a heads-up, though: pushing that much power through a short tube creates a lot of heat soak. Make sure your cooling manifolds are up to the task, or you’re going to fry your connectors. Easy swaps, less stress Nobody likes spending hours on maintenance. We offer a few different end-cap options to make sure you get a tight seal, which is the only way to stop vacuum leaks in the chamber. When a lamp finally gives out, you just pop it out and drop a new one in. No need to rewire your entire rack or spend all day scrubbing the area. It’s quick, it’s clean, and it gets you back to work without the usual headache of introducing new contaminants during a swap.
