For development and prototype

Shin-Etsu handoutai (SEH) will supply the fablication process of compound semiconductor device for custom devices, development, prototype and pilot production.
Capability of wafer process at SEH is from epitaxial wafer to device fablications. We can accept everything from the small-scale customization or product to the partial process testing.

Please contact us if you have any problems with processing materials that contain arsenic, such as GaAs.
If you would like to carry out prototyping or testing that is not listed below, please contact us.

We can also prototype InP/InGaAs system and other systems not listed in the table.
We have experience in manufacturing light-emitting devices with DBR structure.
We can flexibly accommodate the structures with a thick current spreading layer or DBR, which tend to increase epitaxial costs.
