Microelectronics Metrology Solutions for Hard Disc Drive Component Metrology - HDD ETCH Dimension - Environmental - Environmental Data and IT Systems

Precision etch dimension measurement of hard disk heads. In order to reliably produce hard disk heads with proper performance, a disk head manufacturer must be able to measure the etch dimensions accurately. The required precision can be on the order of a few tenths of a micron or less, requiring nanometer-level detection of the pole tip and the locations of the various edges of the etched steps.
