Accelerating research and development, [new] surface analysis service launched!

Not only the surface, but also up to a depth of 30nm - Quantitative evaluation of the chemical state at the surface and inside the material at the same location and non-destructively!

We have launched a new service using XPS/HAXPES starting in June! For increasingly complex materials and fine structure samples, we can evaluate the composition and chemical bonding states from the surface to the interior of the material (up to ~30nm) at the same location and in a non-destructive manner. - Depending on the elements of interest and the analysis area and depth, we can select the appropriate X-ray source (Al Kα/Mg Kα/Ga Kα/Cr Kα) to achieve evaluation under suitable measurement conditions. - Non-exposure measurements to the atmosphere, Ar monomer/GCIB sputter etching, and heating pretreatment can be combined. - It is possible to evaluate the electronic states of semiconductor samples using UPS/LEIPS (ionization potential/electron affinity/band gap).

basic information

In recent years, we have been able to respond to the increasing demand for "quantitative evaluation" of deep regions and "analysis of the bonding state of fine structure samples." By introducing a new Cr line in addition to the conventional Al, Mg, and Ga lines, we have narrowed down the measurement locations while expanding the maximum measurable depth to 30 nm. This allows for evaluation of deep regions even with small spots. Additionally, a significant feature is that XPS (surface analysis) and HAXPES (deep analysis) can be measured at the same location without positional deviation.
