Filed: 2004-12-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a substrate processor where line width uniformity of a pattern can be improved much more.  <P>SOLUTION: When a substrate W (first substrate W) discharged from an indexer cell is the last substrate before a reticle is changed in an exposure device, discharge of a substrate W (second substrate W) which is to be processed next from the indexer cell is once stopped.

On an exposure device-side, an exposure processing of the first substrate W is terminated, and the second substrate W whose resist application processing is finished is carried in at timing when reticle exchange is completed. Thus, time until an exposure processing is to be performed after the resist application processing on the substrate W is completed can be made constant without deteriorating processing efficiency. Consequently, processing history of the substrate W can be made uniform and line width uniformity of the pattern can be improved much more.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
