Vision & Development

CWT always provides customers with products in top quality. Also, we put customers’ demands at first and serve what they need as fast as we can. Therefore, we can continuously satisfy our customers with tailor-made products and services. In recent years, accompanying with an era of information explosion resulted from creations of smart phones and mobile devices, there is enormous growth of needs for communications elements. At the same time, the needs for Sapphire Carrier Wafers expand a lot during making GaAs Wafers. By this point of time, CWT has developed aquired technology and gotten certifications issued by customers. CWT becomes the first high-precision supplier of Carrier Wafers for GaAs Wafer manufacturers.



Gallium arsenide (GaAs) is a compound of the elements gallium and arsenic. It is a III/V semiconductor. Its specialties include high frequency, low noise, efficiency and low power consumption, which are desirable for used on applications of wireless communications. Due to the popularization and penetration of 3G/4G cell phones and smart phones, the demands for GaAs grow rapidly. Besides, because more and more sapphire Optic-Electronics elements are applied to smart phones, the requirements for sapphire Optic-Electronics elements become strong too.
