A 0.3°C drift in the LPCVD furnace profile is enough to push critical thickness targets off-spec. When the heating element starts to underperform, thermal uniformity falls apart, doping and deposition stoichiometry follow, and the lithography stack takes the hit. Photoresist soft bake and hard bake windows narrow, CD control tightens, and etch selectivity starts to drift.</p>
