Getting MEMS Wafer Drying Right

Drying MEMS sensor wafers is a bit of a tightrope walk. If you don’t get the heat distribution just right, surface tension kicks in, you get stiction, and suddenly your delicate sensor membranes are ruined. To stop that from happening, we use specialized infrared (IR) heating elements. The goal is simple: flash-evaporate the leftover liquids instantly, but do it without cooking the sensors.

The Heat Struggle

Here’s the thing about power density. You need the temperature to be dead-on across the entire wafer. If one spot is hotter than the rest, the wafer warps. Simple as that. We build these heaters with high wattage density so they ramp up fast. But there’s a catch. While high power lets you shave time off your drying cycle, it puts a lot of pressure on your power supplies. Just double-check that your electrical feed can actually handle that initial surge of current when the heat kicks in.
