Abstract:
1. In a substrate processing environment, a computer-implemented method for managing substrate processing data, said substrate process data being acquired while a substrate is processed in a plasma-processing chamber of a cluster tool, comprising: receiving meta-data that identifies an identification of said substrate, said meta-data further identifying a process recipe employed for processing said substrate; receiving from a plurality of transducers a plurality of process data streams, each of said plurality of process data streams pertaining to a process parameter being monitored, individual data items in each of said plurality of process data streams being collected; storing said individual data items associated with said plurality of process data streams in a single table; storing said single table and said meta-data in a single file, said single file storing data pertaining to only said process recipe and said substrate; using a process control computer to receive a registration from an application, said registration identifying a file type needed by said application; receiving, using said process control computer, a notification indicating that said single file in accordance with said file type has been created; writing said single file to said process control computer as a written file; updating indexes in a database with said individual data items; after said updating, pushing said written file to said application as a pushed file via a first path; after said updating, notifying said application via a second oath that said pushed file is available; receiving second meta-data that identifies said identification of said substrate, said second meta-data further identifying a second process recipe employed for processing said substrate; and creating a second file for storing said second meta-data and a processing data set, said processing data set resulted from processing said substrate using said second process recipe.
