IR1 High-Resistivity FZ Intrinsic Silicon Wafers, 1-8 Inch
Price range: $2.00 through $590.00
High-Resistivity FZ Intrinsic Silicon Wafers – 1–8 Inch
Product Description
High-resistivity Float Zone (FZ) intrinsic silicon wafers are designed
for semiconductor research, spectroscopy, thin-film deposition,
microscopy and advanced materials applications where high-purity
silicon substrates are required.
Float Zone silicon provides high-purity single-crystal material and is
available in multiple wafer diameters, thicknesses and crystal
orientations. High-resistivity grades are available for applications
requiring reduced free-carrier concentration and improved electrical
isolation.
Wafer diameters from 1 inch to 8 inches are available. Standard
substrate thicknesses include 525 μm, 625 μm and 725 μm, while
customized thicknesses from approximately 50 μm to 12 mm can also
be supplied.
