WebSep 2, 2024 · In flood exposure, the unexposed regions of photoresist become developable. The exposure levels are generally twice as high as the first initial exposure due to the absence of a photomask. To maintain a hydrated surface, rehydration is conducted through water which in turn helps to maintain a high development rate.
