Sample holders
A variety of sample holders are available for the SDCOM, enabling you to process smaller, larger, or irregular samples easily.
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 five seconds.
SDCOM delivers the highest level of precision of up to 0.01o, and with a wide variety of sample holders and transfer fixtures including a marking option for lateral crystal direction, this easy-to-use compact is the ideal solution for many applications within wafer processing and research.
Features and Benefits
Ultra-fast and precise: azimuthal scan method
The azimuthal scan method requires only one measuring circle to gather all the necessary data to fully determine the orientation, which delivers high precision at a very low measuring time – in the range of a few seconds.
The sample is rotated 360o, 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 high precision in a short period of time.
Compact and versatile
SDCOM is lightweight and compact, making it easily movable and able to fit easily into your process – whether in research or industry. 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 1 mm in size, and examples of measurable materials include:
- 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
- Tetragonal: MgF2, TiO2, SrLaAlO4
- Hexagonal and trigonal: SiC 2H, 4H, 6H, 15R, GaN, ZnO, LiNbO3, SiO2 (quartz), Al2O3 (sapphire), GaPO4, La3Ga5SiO14
- Orthorhombic: Mg2SiO4, NdGaO3
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.
User-friendly precision
SDCOM delivers excellent precision of up to 0.01o depending on the sample, and is able to measure crystals ranging from 1 mm and upwards in size. This precision is maintained at the highest speeds thanks to the azimuthal scan method, which provides full characterization of crystal orientation within a single measuring rotation. There is also an option to include a lateral crystal direction marking function.
Thanks to manual handling and intuitive software design, the SDCOM is easy to use and accessible for a range of user types – practical in both research and industry, where user experience levels may vary.
Cost-effective
SDCOM’s X-ray tube is air-cooled, eliminating the need for water cooling. Thanks to the SDCOM’s efficiency and small footprint, its energy consumption is kept to a minimum – and so are your running costs.
