SDCOM

Overview

Quick and precise crystal orientation measurement has never been so accessible – meet the SDCOM, your user-friendly compact XRD. The azimuthal scan method unlocks ultra-fast measurement, with results returned in under ten seconds.

Delivering the highest level of precision of up to 0.01^o while supporting a wide variety of accessories, SDCOM is the ideal solution for many applications within wafer processing and research.

Features and Benefits

Fast and precise: azimuthal scan method

The azimuthal scan method requires only one measuring rotation to gather all the necessary data to fully determine the orientation, delivering results within 10 seconds whilst not compromising accuracy.

The sample is rotated 360^o, with the X-ray source and detector positioned to achieve a certain number of reflections per turn. These reflections enable the orientation of the crystal lattice to be measured in relation to the rotation axis with a high precision of up to 0.01^o.

Compact and versatile

Due to its lightweight and compact shape, SDCOM is easily integrable in research or industry processes. The XRD Suite software is both powerful and intuitive, making it convenient and easy to operate for a range of users.

Flexibility is key to the SDCOM, which is especially clear in the range of materials it can measure. The SDCOM can measure crystals starting from 2 mm in diameter up to 300 mm in diameter

For added flexibility, the SDCOM also supports the Theta-scan. With this you can cover an even larger range of materials and off-cuts.

There is also a variety of sample holders and transfer fixtures that can further expand the possibilities of your SDCOM’s applications, ensuring compatibility with your workflow. Manual and motorized wafer mapping stages are also available.

Examples of measurable materials include (azimuthal scan method):

Cubic, arbitrary unknown orientation: Si, Ge, GaAs, GaP, InP
Cubic, special orientation: Ag, Au, Ni, Pt, GaSb, InAs, InSb, AlSb, ZnTe, CdTe, SiC₃C, PbS, PbTe, SnTe, MgO, LiF, MgAl₂O₄, SrTiO₃, LaTiO₃
