Getting Your Heat Right in a Smart Fab

If you’re building a Smart Fab today, you have to rethink how you handle heat. The old ways of doing things just don’t cut it anymore. For wafer processing, we’re moving toward infrared (IR) systems. They’re basically the heartbeat of how we collect thermal energy and keep heating precise.

The “Goldilocks” Zone

Getting the distance between your IR emitter and the wafer just right is a bit of an art. If you push them too close? You’ll get hot spots. Those little spikes in temperature can warp a wafer in seconds. But if you pull them too far back, you’re just wasting energy by heating up the chamber walls instead of the product. We usually look at the wavelength to figure this out. Shortwave is great when you need heat to penetrate fast. Medium-wave is better if you want the surface to stay stable. It’s all about balancing the lamp’s wattage with that gap to make sure the temperature is the same from one edge of the wafer to the other.
