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 CG 4000 CD-SEM is a Critical Dimension Scanning Electron Microscope that supports 12-inch wafer sizes.[1]
What it is
The Hitachi CG 4000 is a CD-SEM (Critical Dimension Scanning Electron Microscope).[4][1][5]
How it works
General reference — not yet source-verifiedCD-SEMs operate by scanning a focused electron beam across the sample surface. The beam interacts with the sample, generating secondary electrons and backscattered electrons, which are detected to form an image. By analyzing the image, algorithms can extract accurate dimensional information, often with nanometer-scale precision.
