HN1 High-Purity Single-Crystal Silicon Substrates for SEM, XPS & AFM
Price range: $0.00 through $131.00
High-Purity Single-Crystal Silicon Substrates for SEM, XPS & AFM
Product Description
High-purity single-crystal silicon substrates provide a flat and smooth
polished surface for electron microscopy, atomic force microscopy,
X-ray photoelectron spectroscopy, thin-film deposition and other
analytical applications.
Single-side polished silicon substrates are available in sizes from
1 inch to 12 inches. Both CZ (Czochralski) and FZ (Float Zone)
single-crystal silicon materials are available with multiple
thicknesses, crystal orientations, conductivity types and resistivity
ranges.
For AFM applications, precision-polished silicon substrates are
recommended when very high surface flatness is required. The smooth
silicon surface helps minimize substrate-related interference during
nanoscale surface characterization.

Silicon Substrates for SEM & AFM
Silicon substrates used for electron microscopy provide a flat,
smooth and mirror-like surface. The wafer manufacturing process
includes cutting, grinding, multi-wire slicing, mechanical polishing,
chemical etching and chemical-mechanical polishing to achieve a highly
finished surface.
During SEM observation, surface flatness and cleanliness can directly
affect the quality of the observed sample. A smooth substrate helps
clearly display microscopic structures and surface details.
AFM measurements place even higher requirements on substrate flatness.
Precision-polished silicon substrates are therefore recommended for
atomic force microscopy applications where nanoscale surface
characterization is required.
