Getting IR Thermal Sensing Right in the Fab

If you’re trying to build a digital twin for your Fab, you quickly realize that sensors aren’t the hard part. The real struggle is getting a data stream that doesn’t drift. For wafer processing, we lean on high-precision infrared (IR) sensing to grab real-time thermal maps. Without that, your whole thermal management system is basically flying blind.

Why we can’t just “touch” the wafer

Here’s the thing: you can’t just stick a physical probe on a wafer. You’d ruin it instantly. That’s why we use IR sensors. They pick up the radiation coming off the silicon and turn it into a temperature reading. But it’s not as simple as pointing and clicking. You have to deal with emissivity. Since silicon changes how it emits heat based on the temperature and the doping level, you’ve got to calibrate for it. If you skip this step, your data is pretty much worthless.
