The wafer hits the track, the resist gets dispensed, and that soft bake has to land on target within a window tight enough to keep linewidth variation in spec. One bake profile that drifts, one hot spot, and the line starts to walk. There’s no do-over with the thermal budget. The cost conversation around infrared wafer heater lamps never stops at the purchase order. It’s the cost of scrapped lots. The cost of chasing uniformity lot after lot. And the cost of a 2 a.m. lamp failure that shuts the line down. If the lamp can’t deliver sub-millimeter thermal field control with repeatable performance, every other cost control effort in the fab is fighting uphill.</p>
