Title: Method for detecting dust generating part in highly vacuum apparatus for manufacturing ic
Inventor: OKUMURA HIROYUKI
IPC: G01N21/94
Filed: 1991-11-20
Abstract: PURPOSE:To provide a function for detecting a dust generating part in a short time, by conveying every wafer or every batch of wafer continually and reversibly along a desired carrying path. CONSTITUTION:In an IC-processing high vacuum apparatus, dust generating parts are detected in a plurality of processing parts including a vacuum part. In a manufacturing step, a wafer is put, for example, to a carrying path 1 for processing. Several minutes later a wafer is put from a carrying path 2 to a load lock part 5, where the wafer is put in a state for waiting evacuation. While one wafer is carried along the carrying path 2, a wafer is put to a carrying path 3 instead of a carrying path 1, and when its carrying path is completed the wafer is taken out from the load lock part 5. In this way, the wafer is carried forward or backward continually along a desired conveying path to detect a dust generating part. Consequently, this survey can be carried out in a short time.
