Why We Stress-Test Every Single Wafer IR Sensor

In wafer fabrication, one tiny electrical arc is all it takes to trash an entire batch of silicon. It’s a nightmare scenario. That’s why we don’t believe in “spot checks.” Every single lamp and sensor that leaves our shop goes through a full withstand voltage and insulation resistance test. No exceptions.

Finding the weak spots

Here is how it works: we push these components way past their normal operating voltage. We’re basically trying to break them. Why? Because we’d rather find a microscopic crack in the quartz or a tiny impurity in the seal right here in our lab than have it fail inside your machine. If the insulation gives way or the leakage current spikes, the unit is garbage. We scrap it.

High precision heat for wafer IR

Out on the fab floor, the lithography cluster keeps moving, no pause button. The track feeds the wafer, the resist spins, the edge bead gets stripped, and the bake has to land inside a tight thermal window—every single pass. A 1°C drift during soft bake or hard bake shifts critical dimension, throws off swing curves, and eats into dose margin. When the bake module can’t hold uniformity across the wafer, you see it fast: footing, scumming, and yield loss that shows up right in the electrical test bins. Wafer IR heating isn’t about “warming” the wafer. It’s about delivering repeatable, wafer-level thermal control that fits cleanly into the lithography flow and behaves predictably under production pressure.
