Abstract:
1. A coating and developing apparatus carrying out coating of a resist film upon a substrate taken out from a carrier fed into a carrier block, said coating and developing apparatus further applying a developing process to a substrate finished with an exposure process in an exposure apparatus, said coating and developing apparatus further carrying out, after processing of substrates of a preceding lot, processing of substrates of a subsequent lot, said coating and developing apparatus comprising: a wait module in which a substrate coated with a resist film and ready for an exposure process waits for transfer; a transfer unit transferring said substrate waiting in said wait module to a feed-in port of said exposure apparatus, said transfer unit being further fed with a substrate finished with an exposure process from a feed-out port of said exposure apparatus and transferring to a selected heating module selected from a plurality of heating modules; a calculation unit calculating, during said processing of substrates of said preceding lot, a timing for transferring out a first substrate of said subsequent lot to be processed with said heating module from said wait module for each of said plurality of heating modules; a control unit controlling said transfer unit such that a first substrate of said subsequent lot is transferred out from said wait module with a timing calculated with said calculation unit, wherein said calculation unit obtains, for a current heating module included in said plurality of heating modules, a waiting time t defined as a time interval from a time point in which a first substrate B t said calculation unit obtaining said time t a predicted residual time t a time interval t said calculation unit further obtaining said time t a time interval t a time t a time t said calculation unit further calculating said residual time t said calculation unit calculating said predicted residual time t said transfer unit transferring out said substrate B
