Epitaxy Technology

With years of accumulated experiences of mass production, manufacturing, R&D and epitaxial structure design, HLJ has become a forerunner of manufacturing III-V group compound GaAs based VCSEL. From epitaxial structure designs to chip manufacturing processes, we fully control the whole R&D and production know-how, and this has brought advantages for HLJ in quality control and price competitiveness. Our facilities include Metal Organic Chemical Vapor Deposition machines (MOCVD), Double Crystal X-Ray Diffractometer (X-Ray), PL wavelength & Reflection measurement machine, Electrochemical Capacitance Voltage Profiler (Ecv), and Hall machines, etc., which enable HLJ to conduct full spectrum quality analyses on Epitaxial wafers.

HLJ is proud for its independent epitaxial structure design ability. Our main products include standard 850nm and 940nm, 680nm VCSEL wafers. HLJ also works with customers to develop customized products with special specification of wavelength.
