* Silian COB overview

Chongqing Silian Optoelectronics Science & Technology Co., Ltd was founded by China Silian Instrument Group Co., Ltd for the development of LED industry. After the acquisition of Honeywell Sapphire business, the company has become China’s first enterprise with the world’s top-quality large-sized sapphire production and R&D capabilities. The company has the world’s leading high-power sapphire substrates technology. Taking the excellent oppotunity, the company has developed LED packaging, LED lighting applications and other industries in succession to project extension in LED industrial chain. Based on the core-technology of sapphire substrates, we have created an area of 1000 mu (approximately 66.7 hectares) to develop LED industrial china from basic materials to high end products and become the most completed and largest semiconductor energy-efficient in dustrial base in Western China.

Maintaining the enterprise spirit of “People oriented, Natural Selection, Inheriting innovation and Pursuit of Excellence” and the customer tenet of “Silian is guided through customers and stands with customers”, we are committed to provide customers with high-quality sapphire chip substrates, optical window materials, LED packaging devices, and high efficiency LED lighting desplay high end products and creating value for customers.

Silian the international large-sized sapphire substrates standards lauching member.

Acquiring the completed production line from sapphire crystal growth to substrate processing.

We have the qulity advantages of high purity, high consistency and high repeatability.

Cooperating with world top level LED chip manufactures.
