Polished silicon is an excellent substrate for imaging experiments, nanotechnology and micro-fabrication applications. For imaging applications, it is an ideal sample substrate for small particles due to the low background signal of the highly polished surface. For biological applications silicon resembles glass, which makes it a suitable support for growing and/or mounting cells.
The silicon wafers and chips are all P-type, doped with B to provide excellent conductivity for SEM, FIB and STM applications. It is available as wafers, diced wafers or as smaller chips (pieces). The silicon wafer and chips all have a <100> orientation. Cleaving of the wafers to the desired size with a <100> orientation wafers is straight forward and simple.
Micro-Tec silicon wafer substrates from Micro to Nano are a useful flat substrate for SEM imaging of particles due to the low background and can also be used as sample substrates, micro-fabrication, substrate for thin film research or biological substrates. Micro-Tec Si wafers are packed in a wafer carrier tray for protection. The diced wafer supplied on wafer adhesive disc and packed between two plastic sheets for protection. The Si chips can be easily lift off the adhesive sheet.
