How we workProduct Categories
Silicon Wafers
Prime, test and dummy grade silicon in common and non-standard diameters, cut and polished to order.
Oxide & SOI Wafers
Silicon with grown oxide layers and silicon-on-insulator stacks for MEMS, photonics and power devices.
Glass & Quartz
Borosilicate glass and fused silica wafers with tight flatness for optics, packaging and microfluidics.
Compound Substrates
Sapphire and other single-crystal substrates for LED, RF and wide-bandgap research.
Featured Products
View all →Borosilicate Glass Wafer
Low-expansion glass wafers suited to anodic bonding with silicon, polished to optical quality.
Polished Silicon Wafer
Single- or double-side polished CZ and FZ silicon, 2" to 12", with custom thickness, doping and orientation.
Sapphire Substrate
Single-crystal Al₂O₃ substrates in C, A, R and M planes, flat or patterned.
Thermal Oxide Wafer
Silicon wafers with a dense, uniform SiO₂ layer grown by wet or dry oxidation, from tens of nanometres to several microns.
SOI Wafer
Silicon-on-insulator wafers with selectable device layer, buried oxide and handle thickness.
