Claim Text:
1. A method of processing a plurality of substrates belonging to the same lot in succession by using a processing apparatus body and a controller for controlling said processing apparatus body, said processing apparatus body including a substrate holding part for holding a substrate, a rotary drive part for rotating said substrate holding part, a liquid chemical supply part for supplying a liquid chemical to said substrate held by said substrate holding part, a rinsing liquid supply part for supplying a rinsing liquid to said substrate held by said substrate holding part, and a cup surrounding said substrate holding part, said method comprising the steps of: (a) previously setting a plurality of substrate processing modes in said controller; (b) selecting one of said substrate processing modes set in said controller for each of said plurality of substrates to cause the selected substrate processing mode to be executed; and (c) detecting an occurrence of trouble in said processing execution step, said substrate processing modes including: (A) a normal mode applying to a first substrate which is a substrate belonging to said lot to be executed in the case where the occurrence of said trouble is not detected in said detecting step, wherein said normal mode having a first liquid chemical process which supplies the liquid chemical to said first substrate while rotating said first substrate held by said substrate holding part to perform liquid chemical treatment on said first substrate, and a first rinsing process which supplies the rinsing liquid to said first substrate while rotating said first substrate held by said substrate holding part to rinse away the liquid chemical from said first substrate; and (B) a special mode applying to a second substrate which is a substrate belonging to said lot and to be processed after the time point of detecting the occurrence of said trouble in the case where the occurrence of said trouble is detected in said detecting step, wherein said special mode having a second liquid chemical process which corresponds to said first liquid chemical process in said normal mode and a second rinsing process which supplies the rinsing liquid to said second substrate while rotating said second substrate held by said substrate holding part under an operating condition different from that in said first rinsing process to clean said cup with the rinsing liquid flown off from the rotating second substrate while rinsing away said liquid chemical from said second substrate, executing at least one of the processes of a positional adjustment sub-process which adjusts a portion where the rinsing liquid flowing off from said second substrate makes contact with said cup by vertically moving said cup, a speed adjustment sub-process which adjusts a rotation speed of said second substrate variable, and a supply quantity adjustment sub-process which adjusts a supply quantity of said rinsing liquid to said second substrate.
