It shows up as linewidth variation, scumming, and yield bleeding away. Thermal budgets are already tight, and the oven or hotplate simply can’t afford excursions that push the photoresist outside the right <a href="https://o-yate.com">glass</a> transition window.</p> <h2 id="what-matters-technically">What matters, technically</h2> <p>We built the thermal analyzer heating lamp around short-wave infrared (SWIR) halogen emitters in a quartz envelope, tuned to match the absorption profile of common photoresist stacks. Across the bake surface, wafer-level uniformity holds within ±0.1°C, and setpoint repeatability keeps the thermal profile locked to the recipe. It runs in cleanroom classes 1–100 without spiking particle counts, using a low-outgassing assembly and a laminar-flow-compatible housing that meets SEMI S2. Output stays stable over 5,000+ hours, with less than 5% intensity drift, so the same thermal dose lands run after run.</p>
