Why We Use Gold Reflectors for IR Curing

The semiconductor world is pushing hard toward lead-free, eco-friendly standards. It sounds great on paper, but in the actual fab, it’s a headache. Standard convection ovens just aren’t cutting it. They spend way too much time heating up the air before they even touch the part. It’s a waste of power, and honestly, it’s a great way to accidentally contaminate your wafers. That’s why we stick with infrared (IR) bulbs and gold reflectors.

Stop Wasting Heat in Your Wafer Processing

When you’re heating silicon wafers, every single watt matters. But here’s the problem: standard quartz lamps are leaky. They bleed a ton of energy out the back and sides where it does absolutely nothing for your process. That’s why we use gold-coated twin tube lamps. By putting a high-purity layer of gold on the back of the tube, we basically turn the lamp into a spotlight for heat.

Keeping Your Class 100 Cleanroom Actually Clean

If you’re running a Class 100 cleanroom, you already know the nightmare of outgassing. One tiny bit of particulate shedding from a heating element and your semiconductor wafers are ruined. It’s frustrating. Most standard infrared lamps just can’t hack it—they break down under the heat and start spitting out microscopic debris right where you don’t want it. We figured out a way to stop that. We use high-purity synthetic quartz and a gold-reflective coating. Simple, but it works. Why the gold? It’s not about looking fancy. We put a thin layer of gold on the back of the quartz envelope because gold is incredible at reflecting infrared radiation—about 98% of it, to be exact. Instead of letting heat bleed out everywhere, we push it all forward toward your target. This means you aren’t wasting energy, and your HVAC system doesn’t have to work overtime to keep the room cool. Plus, you hit your target temperatures way faster without having to crank the wattage to some scary level. The grit and the glass We stick with high-purity quartz because cheap glass just burns out. Quartz can take a beating. You can cycle the power on and off, and it won’t crack from the thermal shock. As for the gold, we use a vacuum deposition process to lock it to the quartz. We did this because if that coating flakes or peels, you’ve got particles on your silicon. And that’s the last thing you want. This process makes sure the gold stays put. Getting it running These lamps are basically drop-in replacements for your curing and drying stages. You can wire them right into your current controllers. But here is the catch: keep an eye on your heat density. Because that gold coating is pushing almost all the energy forward, the front of the lamp gets much hotter than a clear one. Just make sure your shielding and cooling fans are up to the task. You don’t want a concentrated blast of heat accidentally frying a nearby sensor.
