## About

Established in 2017 and based in Xi'an, China, WaferChina operates as a semiconductor manufacturer, focusing on the development and production of III-V compound semiconductor epitaxial wafer with GaAs (gallium arsenide) and InP (indium phosphide) as the substrate, and specially provides customized epitaxy growth services. In October 2025, WaferChina raised a strategic investment from new investor Puhua Capital.

The company offers GaAs VCSELs (vertical cavity surface-emitting lasers), GaAs EEL (edge-emitting lasers) /PD (photodiode), GaAs HBT (heterojunction bipolar transistor), and InP DFB (Distributed Feedback)/ FP (Fabry-Perot)/ PD (Photodiode).

The company generates revenue by supplying GaAs VCSEL, GaAs EEL/PD, GaAs HBT, and InP DFB/FP/PD.

The company will use the latest funding to accelerate its technological research and development and expand its production scale, further consolidating its technological advantages and market position in the field of compound semiconductor materials.
