Semiconductor Wafer Division

Inseto is a leading UK-based semiconductor wafer and substrate supplier, proudly supporting customers worldwide in research, academia, and high-tech manufacturing. We supply a comprehensive range of high-quality wafer materials that meet strict standards for flatness, cleanliness, and crystal orientation. These include:

• Silicon Wafers – Prime, test, and mechanical grade
• Silicon Oxide Wafers – SiO₂ wafer coatings
• Silicon Nitride Wafers – Si₃N₄ wafer coatings
• Glass & Fused Silica Wafers – Ideal for photonics and microfluidics
• Silicon-on-Insulator (SOI) – For advanced device & MEMS fabrication
• Silicon-on-Sapphire (SOS) – Specialised substrates for thermal and optical environments
• Sapphire – High-purity substrates for thermal and optical environments
• Compound Semiconductor Wafers – Including SiC, InP, GaN, GaAs and Ge

For applications requiring oxide or nitride coatings, our silicon wafers can be processed using atmospheric thermal oxide: dry oxide (for thinner layers); wet oxide (for thicker layers) or PECVD oxide (when single-sided coatings are required). Additionally, for nitride coatings, we offer PECVD, LPCVD, or low-stress LPCVD options.

Inseto also provides a range of additional fabrication processes to tailor wafers to your exact requirements. These include thinning, plating, bumping with solder or copper pillars, and dicing to virtually any die size.

All wafers are available in SEMI standard, PRIME, TEST, and custom thicknesses, with single or double-side polish and full traceability via Certificates of Conformance and compliance with industry standards.
