CDR40-EBD
|
|
40 nm full carbon CD probe. Low vertical edge height, constant edge radius maintains resolution over tip life.
Ordercode: CDR40_NCHR_3
The nanotools CDR-EBD probes for 3D reference and hybrid metrology: with a full range of CDR-EBD probes from 130 nm down to 20 nm, this is pushing the limits of 3D-AFM technology for measuring tight dimensions and extending its capability for future nodes. It brings EBD´s key strength: precise tip orientation, precise control in tip dimensions (length, total diameter, vertical edge height, overhang) and large volume production to undercut applications. These tips do not have a wear resistance coating - but made from bulk wear resistance diamond like carbon.
