Reflow photoresist
WebPurpose of Reflow of Photoresist Structures While the thermal softening and roundening (reflow) or developed photoresist structures is undesired during e. g. metallization, the … WebP4000 photoresist films thicker than 4.0µm require a rehydration hold between soft bake and exposure. Hold times are typically 30-60 minutes (depending upon film thickness) @ relative humidity 40 - 45%. EXPOSURE AZ P4000 is sensitive to exposure wavelengths between 310 and 450nm. 365-436nm is recommended. POST EXPOSE BAKE

Web‐For layers ≥ 150 m, allow the wafer to rest on the spinner so hanging resist can retract onto the wafer before cleaning the edge bead. If the outer 2‐5 mm of resist is removed, it will reflow into the void during baking. Softbake (Always level the hotplates) ≤ 10 microns WebMaterial re-deposited on the resist structures during dry etching will also make it difficult to remove the resist film. Using Solvents as Remover Acetone is not well-suited as stripper for photoresists: The high vapour pressure of acetone causes a fast drying and thus re-deposition of stripped photoresist onto the substrate form-ing striations.
