The photoresist has to hit the target <a href="https://goldisgood.com">temperature</a>—clean, uniform, across every die. Give the hot zone a 1°C drift, or let a cold spot show up at the edge, and critical dimension control walks. The line stops.</p> <h2 id="what-actually-matters-under-the-hood">What actually matters under the hood</h2> <p>We built the bake around zoned heating, with independent elements that respond fast and hold tight thermal uniformity across the wafer plane. During soft bake and hard bake, the system keeps setpoint stability within ±0.1°C, and the ramp profiles repeat—so you protect the resist profile and keep standing waves from showing up. Quartz and short-wave infrared sources deliver the heat quickly and cleanly, with low particulate. The controller watches each zone in real time, so it can compensate for edge effects and for the usual tool-to-tool variation.</p>
