X-Prep® Vision™
The X-Prep® Vision™ is a metrology tool that enables measurement of silicon and semitransparent substrates. It is necessary for applications that require uniform thinning to a specific target with a tolerance of +/- 3 µm or better.
The X-Prep® fixture adapter is also secured to the motorized stage on the X-Prep® Vision™, ensuring the measurement/tool control coordinates remain aligned when transferred between systems.
A library with over 130 materials (i.e., GaAs, InGaAs, SiC, Sapphire/Al2O3, InP, SiGe, GaN, photo-resist) is included with every system.
Measurement & Observation - How it Works
IR light is focused onto a sample, and a unique signal based on the refractive index of the material is created. The return signal is analyzed by the software to produce a thickness value.
Measuring Below 10 µm Thickness
For applications requiring thinning to less than 10 µm, precise measurement is possible only by adding the visible light spectrometer accessory.
