NEXIV VMZ-K6555 - Ground-breaking multi-functional confocal video measuring system

nikon metrology vision systems VMZ K6555The Nikon Confocal NEXIV VMZ-K6555 was developed on the strength of Nikon's leading opto-mechatronics (optical, mechanical and electronic) technologies. It incorporates a variety of confocal optics for fast and accurate evaluation of fine three-dimensional surface metrology, image processing technology, and TT L laser autofocus. It allows both 2D and height measurements in the same field of view.

The Confocal NEXIV VMZ-K6555 is used for the inspection and measurement of critical dimensions of highly complex structures on advanced semiconductor devices, probe cards, substrate patterns on circuit boards, MEMS and a variety of other demanding applications.


Key benefits

  • Simultaneous wide-area height measurement with Nikon proprietary confocal optics
  • 2D measurement with 15x brightfield zoom optics
  • Fully compatible with 300 mm wafer measurement at semiconductor fabs
  • Handles printed circuit board sizes with its 650 x 550mm stroke


  • IC Packages: Flip Chip/COF(Bump)/COG, CSP (FBGA)/SIP (Bump, Wire), Interposer (Pad height)
  • MEMS
  • Probe Card (Silicon Probe, Au Probe)
  • Precise Glass Components (Micro Lens, Contact Lens)
  • Photo Spacer Width/Height for Color Filter for FPD Panel
