Nikon’s Confocal NEXIV delivers a new dimension in IC metrology.
The 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.

Confocal Technology Advantages
Widely used in bio-science research, confocal microscopy offers several advantages over conventional optical microscopy, including controllable depth of field, the elimination of image degrading out-of-focus information, and the ability to collect serial optical sections from material samples. The key to the confocal approach is the use of spatial filtering to eliminate flare in material sample images. The Nikon Confocal NEXIV uses a Nipkow disk, which features multiple, symmetrically placed spirals of pinhole apertures through which light is passed and split into mini-beams. As the disk rotates, each beam scans across a portion of the sample field and generates a 3D image. The image is projected into a digital CCD camera using optical sectioning technology. The result is a 3D image captured in one scan delivering highly accurate and reliable height measurement data.
