Inseto provides high quality Oxide and Nitride Coated Wafers where either one or both wafer surfaces have been enhanced with a controlled layer thickness.

Our oxide wafers (SiO2 Silicon Oxide) are coated using either atmospheric thermal oxide (ATOx), which always coats both sides of the wafer, dry Oxide that produces a thinner oxide layer but with a higher uniformity film and PECVD Oxide, which produces a coating on a single side of the wafer.

Highly controlled thickness enables photonic devices to be fabricated on chip and integrated photonics within other electronic structures. These wafers are also very widely used as substrates for 2D materials exfoliation where the exceptional thickness and refractive index control gives reliable flake location. SiO2 layers are also used as etch stop layers where stress and flatness must be tightly tolerance.

Our Nitride wafers (SiN - Silicon Nitride) are produced by using either PECVD, LPCVD or low stress LPCVD. These variants are changes in the method of deposition and alter the final physical and mechanical properties of the film enabling fabrication of X ray windows and membranes as well as cladding layers in Photonics devices.

A large percentage of wafers we ship are coated or processed in some way and we are able to offer a wide range of additional steps, to facilitate your onward processing. This service can save you substantial time in searching for suppliers of these layers yourself and our regular supply chain for this work enables rapid turnaround and advantageous pricing.
