Sub-Nanometer Profile Metrology In The Wafer OCD Measurement System Market

As semiconductor manufacturing advances beyond 3nm logic nodes and high-density 3D NAND flash memory stacks exceed three hundred vertical word-line layers, validating the physical dimensions of complex 3D nanostructures has become a primary metrology challenge. While traditional scanning electron microscopy (CD-SEM) provides high-resolution top-down images, it cannot measure internal vertical...
