A Plane Sapphire Semiconductor

What Is A-Plane Sapphire?

The plane that is perpendicular to the A-axis, containing the C-axis. A-plane Sapphire orientations are widely used in optoelectronic applications.

How do Researchers Use A-Plane Sapphire Substrates?

Chemical Vapor Deposition (CVD) has been used by researchers to grow AlGaN epi-layers on a-plane sapphire. And to grow MoS2 to make more efficient electronic devices.

Reseachers have used a-plane sapphire to grow Polycrystalline Diamond Thin Film using the CVD process.

Ion Beam Milling of Single-Crystal Sapphire on A-Plane Sapphire

The removal rate of material (MRR) is the speed at which material is removed from the surface. The surface roughness (Sa) is how rough the surface is after the material is removed. The MRR of A-plane sapphire is slightly higher than that of C-plane and M-plane sapphire. The Sa of A-plane sapphire after FIB treatment is the smallest among the three different crystal orientations. These results imply that A-plane sapphire allows easier material removal during FIB milling compared with C-plane and M-plane sapphires. Moreover, the surface quality of A-plane sapphire after FIB milling is better than that of C-plane and M-plane sapphires. The theoretical calculation results show that the removal energy of aluminum ions and oxygen ions per square nanometer on the outermost surface of A-plane sapphire is the smallest. This also implies that material is more easily removed from the surface of A-plane sapphire than the surface of C-plane and M-plane sapphires by FIB milling.

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.
