Typical Silicon-on-Sapphire (SoS) Packaging for One Wafer

Silicon on Sapphire Wafers

Pre-cut 4'' Silicon-on-Sapphire (SOS) Wafer

We can pre-cut SoS wafers into diced pieces.

Sapphire thickness 460+/-25um,we have 400nm SOS based on 460um DSP R-sapphire,if need SSP SOS,we have it with >/=600nm Si on 460+/-25um SSP Sapphire.

Wafers for Metasurfaces Research

600nm thick Silicon deposited on on sapphire wafers have been used from research clients for their academic research metasurfaces.

Our Research Client States:

We will use e-beam lithography to fabricate designed silicon
nanostructures on the sapphire wafer, which is called as

Metasurfaces can be used to manipulate the wavefront,
propagation direction, or focusing of light.

Silicon on Sapphire (SoS)

The advantage of sapphire is that it is an excellent electrical insulator, preventing stray currents caused by radiation from spreading to nearby circuit elements.
