Abstract:
A deep ultra-violet (DUV) track system, said system comprises:an indexer end station for storing a substrate;a vapor-prime chamber connected to said indexer end station, wherein said substrate is heated and a chemical solution is applied on a surface of said substrate in said vapor-prime chamber before a photoresist layer is coated on said substrate, a base gas being introduced into said vapor-prime chamber to harden a surface of said photoresist layer;at least one chill-plate chamber connected to said vapor-prime chamber for bringing said substrate to a stable, constant temperature;a coater chamber connected to said chill-plate chamber for uniformly coating said photoresist layer on said substrate;at least one vacuum-bake chamber connected to said coater chamber for heating said photoresist layer;a stepper chamber connected to said vacuum-bake chamber through an interface chamber, wherein said photoresist layer is exposed in said stepper chamber; anda developer chamber connected to said chill-plate chamber, wherein exposed or unexposed portion of said photoresist layer is removed in said developer chamber.
