Why we’re ditching the old ovens for IR curing

For a long time, semiconductor fabrication relied on those massive convection ovens. But honestly? They’re becoming relics. We’re moving toward infrared (IR) curing now, mostly because it actually hits those “green” and lead-free targets that everyone is chasing these days. Instead of just blowing hot air around, IR uses electromagnetic radiation. It goes straight for the wafer surface. No middleman.

Getting the heat where it actually belongs

Think about how a convection oven works. You heat the air, and then the air heats the wafer. It’s a waste of power. IR is different. It bypasses all that. The photons dive right into the photoresist or solvent layer and trigger a reaction immediately. The best part? We can stop using those nasty toxic catalysts and lead-based stabilizers that used to be the norm. We usually stick with short-wave IR for this. It packs the most punch. Because the heat hits so hard and fast, the wafer spends way less time in the heating zone. Less time under the lamp means lower power bills. Simple as that.

What’s Under the Hood: Power and Size

Here’s the thing about this heater—we built it around a quartz halogen core because it throws out intense, focused heat. It’s a 2500W unit, wired for 400V. That higher voltage means the current draw stays low, so you can keep the wiring thin and easy to manage. The tube is just 300mm long, which keeps the footprint small. It slips into tight spots without giving up a single watt of output. And that power density? It’s why the temperature shoots up fast, so you’re not standing around waiting for the shop to warm up.
