Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
The Hitachi PD 3000 is a mask visual inspection tool. The Hitachi PD 3000 supports 8-inch wafers. The Hitachi PD 3000 was introduced in 1994.[1]
What it is
The Hitachi PD 3000 is a mask visual inspection system.[1]
Where it fits in the process flow
General reference — not yet source-verifiedMask inspection is performed after the mask has been written, etched, and cleaned, but before the reticle is released for use in wafer lithography. The inspection step serves as a quality control gate in the mask manufacturing process. Defective masks may be sent for repair, or if irreparable, rejected. After inspection, acceptable masks proceed to the wafer fab, where they are used in steppers or scanners to pattern wafers.
