Customized Sample Fixture

Park Systems can prepare customized sample fixtures to support customers’ specific samples, row bars or individual sliders. The customized sample fixture guarantees a superior connection between the measuring sample and the XE-PTR.


Automatic Tip Exchange (ATX)

Automatic Tip Exchange performs fully automated tip exchanges in order to seamlessly continue automated measurement routines. It automatically calibrates cantilever location and optimizes measurement settings based on measurements of a reference pattern. Our novel magnetic approach to the tip exchange yields a 99% success rate, higher than the traditional vacuum techniques.


Ionization System

Ionization system effectively removes electrostatic charges. It ionizes the charged objects and is very reliable since the system always generates and maintains an ideal balance of positive and negative ions without causing any contamination to the surrounding area. It also reduces the accidental electrostatic built-in charge that may occur during sample handling.
