product details

Custom Sapphire Wafer, Sapphire Substrate for Semiconductor & Optics

We supply high‑quality sapphire wafers and substrates, available in round, square and rectangular shapes. Multiple crystal orientations are optional. Products cover thin wafers, thick substrates, sapphire slabs, cylindrical blanks and sheet pieces.

Sapphire wafer features high mechanical hardness, excellent thermal conductivity, outstanding chemical corrosion resistance, and broad‑spectrum optical transmittance. Surface can be fine polished, lapped or etched according to requirements. Custom edge chamfering, cutting and special‑shape processing are supported.

We fully customize diameter, thickness, crystal orientation and surface treatment based on customer drawings or specifications. Strict inspection is implemented for flatness, surface roughness and dimensional tolerance. Suitable for LED epitaxy, semiconductor, optical instrument and industrial sensor applications. Factory direct supply for sample evaluation and mass‑volume production.
