Sapphire is a single crystal of alumina and is the second hardest material in nature, after diamond. Sapphire has good light transmittance, high strength, collision resistance, wear resistance, corrosion resistance and resistance to high temperature and high pressure, biocompatibility, can be made into various shapes of objects. It is an ideal substrate material for making semiconductor optoelectronic devices.

Application: Sapphire single crystal is an excellent multifunctional material. Can be widely used in industry, national defense and scientific research and other fields (such as high temperature resistant infrared window). It is also a widely used single crystal substrate material. Is the current blue, purple, white light emitting diode (LED) and blue laser (LD) industry of the first choice substrate (need to epitaxy gallium nitride film layer on sapphire substrate), is also an important superconducting thin film substrate. In addition to making Y- series, La- series and other high temperature superconducting thin films, it can also be used to grow new practical MgB2 (magnesium diboride) superconducting thin films.

OPTICAL PROPERTIES

Founded in 1999, Hangzhou Freqcontrol Electronic Technology Ltd. is a China leading manufacturer of piezoelectric crystal wafers, substrates, components and single crystal growth. We, known as the "CQT Group" in global market, headquartered in Hangzhou, China, empowered by its manufacturing sites in Shanghai, Jiaxing and Deqin etc.

Our products are mainly used in RF Telecom, Semiconductor, Biotech, Optical engineering and frequency control industries. The monthly production capacity: 500K single quartz blanks (SC, AT, IT, FC, etc.), 20K quartz wafers (AT, ST, X, Z, etc.), 10K LiNbO3 wafers (3~8 inch), 10K glass wafers (Fused silica, Borofloat33, Corning, etc.), 8K LiTaO3 wafers (3~6 inch), and 100K filters/oscillators (VCXO, TCXO).

Our company vision is to be a reliable primary Microelectronic substrates supplier in today's world.

The CQT Group consists of five major plants with total floor area over 10,000 m². Our production machines include crystal growth furnace, wire saw, X-ray orientation, grinding machine, polishing machine, chamfering machine, CNC, REDOX chambers etc. Inspection equipment include Flatmaster 200, AOI, profilometer, optical imager, X-ray inspector etc. We are also equipped with Class 100 and 1000 clean rooms.

The CQT group is primarily known as the expert of hexagonal crystals, We master the manufacturing process of single & doubly rotated quartz blanks, and we can provide quartz of any orientation cut whether given by IRE , Miller index, Euler angle or conventional sign.

In addition to our leading quartz blank manufacturing capabilities, the last decade sees our major technological breakthroughs. We overcome the 3~6 inch ultra-thin wafer mass production barrier, obtained the reduction technology of black LiNbO3 & LiTaO3 wafers, and achieved 8 inch LiNbO3 wafer mass production successfully.
