Silicon Wafers
SPI Supplies offers silicon wafer substrates in both bare chip form and gold-coated form for use as flat, rigid support surfaces in microscopy and materials science sample preparation.
Manufacturer: SPI Supplies — USA
Overview
SPI Supplies offers silicon wafer substrates in both bare chip form and gold-coated form for use as flat, rigid support surfaces in microscopy and materials science sample preparation. The gold-coated silicon wafer substrate provides a conductive metallic surface over the rigid silicon base, suitable for applications such as specimen mounting, calibration, or reflective/conductive support work. Silicon chip substrates are supplied as small flat pieces for general sample support, calibration, or as a base for further thin-film deposition. These substrates combine the mechanical flatness and rigidity of single-crystal silicon with straightforward handling for laboratory sample preparation.
Product Options
The line includes a 4 in (100 mm) diameter gold-coated silicon wafer substrate and a range of silicon chip substrates sold under the SPI Supplies brand. The gold coating provides a conductive, reflective surface while retaining the flatness of the underlying silicon wafer.
