Keeping Your Class 100 Cleanroom Actually Clean

When you’re working in a Class 100 environment, “efficiency” takes a backseat. The only thing that really matters is particle control. The problem is that most standard IR lamps are kind of messy. They off-gas or shed tiny bits of debris from their seals and end caps. It’s invisible, but it’s there. We deal with this by using high-purity quartz tubes paired with specialized ceramic end caps.

Why the materials matter

Here’s the thing: most IR emitters rely on adhesives or cheap plastics where the tube ends. In a high-temp cleanroom or a vacuum, those materials just break down. That’s how you end up with contamination on your wafer. We switched to high-purity synthetic quartz. It doesn’t flinch under thermal shock and it stands up to chemical etching. But the real secret is in the ceramic end caps. We use high-alumina ceramics without any metallic binders. This stops that annoying “dusting” effect you see with cheaper lamps and ensures no organic volatiles leak out when you’re ramping up the heat.
