A soft bake that&rsquo;s off by even a fraction of a degree across the wafer shows up in the photoresist profile—edge beads, thickness gradients, and linewidth control that drifts out of spec. Right after cleaning, the drying step is where residual moisture and micro-droplet marks turn into yield <a href="https://o-yate.com">killers</a> that don&rsquo;t show themselves until after the expensive mask and exposure steps are already done. The heater under the wafer can&rsquo;t just be warm. It has to be precise, clean, and repeatable, <a href="https://o-yate.net">shift</a> after shift. We built the automated wafer drying heater to live in that reality. This isn&rsquo;t a general-purpose hot plate dressed up for the cleanroom. It&rsquo;s a process-critical thermal module designed around the constraints of lithography and wafer prep, where temperature uniformity, particle control, and uptime are non-negotiable.</p>
