Mess up the thermal step that follows by even a hair, and you’ll see the photoresist profile drift, edge bead stick around, and the next lithography overlay target miss. That’s not a hypothetical—it’s a yield leak you can count in scrap wafers. Wafer drying lamps aren’t just heat sources. They’re the last, decisive move in the thermal budget of wafer prep, and they directly set up what the photoresist will do in soft bake and hard bake. When you spec a drying lamp, you’re really buying repeatability: hitting the same temperature profile, wafer after wafer, shift after shift.</p>
