Specimen support for SEM, SIMS, AFM.

They are useful as a smooth, inert background is for the determination of resolution and contrast of "in-the-lens" SEMs equipped with high brightness electron emitters. Additionally, conducting specimens, or non-conducting specimens in low vacuum or low voltage SEM, may be viewed without coating.
Si chips are opaque, have low electrical resistance, are very smooth, brittle and hard like glass. Si chips are chemically quite inert. These chips are pre-cleaned, but for tissue and cell culture, additional cleaning and sterilising may be required.
Si-chips are opaque, of low electrical resistance and have surface properties equal to glass (including smoothness). They are also good substrates for growing or mounting cells. Si-chips are precleaned before packaging. Also ideal for imaging small particles due to low background signal.

The wafers are cut into chips measuring 5 x 5mm, 5 x 7mm or 10 x 10mm.

Before dicing they are rinsed in de-ionized water for cleaning
