Abstract:
1. A method for manufacturing a semiconductor device, wherein process recipes used in individual processes stored in a manufacturing execution system are transmitted to a manufacturing apparatus and a lot of semiconductor devices is then subjected to processing, the method comprising steps of: a) inserting a process control system into a path of a local area network on which the manufacturing execution system and the manufacturing apparatus are connected with each other; b) obtaining a pattern size required in a lithography process at the process control system; c) rewriting, in accordance with the obtained pattern size, a process recipe, transmitted by the manufacturing execution system, for an etching process that follows the lithography process; and d) transmitting the rewritten process recipe for the etching process from the process control system to the manufacturing apparatus after step (c), a value of an oxygen flow rate included in the process recipe being rewritten at step (c).
