As semiconductor technology continues to evolve, sapphire substrates have become a key material in the fabrication of LEDs, power devices, RF chips, and optoelectronic components. Owing to their excellent mechanical strength, chemical stability, high optical transparency, and electrical insulation, sapphire substrates

Sapphire (Al2O3) belongs to the hexagonal crystal system, with its crystal orientations typically defined by crystal planes (hkl) and crystal axes (a, b, c). The crystal axes consist of three directions: a, b, and c. Among these, the a and b axes form a 60-degree angle on the plane, while the c axis stands perpendicula

In the world of advanced materials and microelectronics, sapphire wafers have become increasingly significant due to their exceptional physical, chemical, and optical properties. Whether used in LED manufacturing, semiconductor substrates, or optical applications, sapphire wafers offer a wide range of benefits that mak

1. Material Properties of Sapphire substrateCrystal Structure:Sapphire (α-Al₂O₃) belongs to the hexagonal crystal system and exhibits a highly ordered atomic arrangement.

In silicon carbide (SiC) wafer manufacturing, orientation flats (flat edges) and notches are two common methods used to indicate the wafer’s crystal orientation and axes, aiding precise alignment during the manufacturing and handling processes. The choice between these two marking designs reflects different techn

SiC is a binary compound formed by Si and C elements in a 1:1 ratio, i.e., 50% Si and 50% C, with its basic structural unit being a Si-C tetrahedron.

For example, Si atom diameter is larger, equivalent to an apple, while C atom diameter is smaller, equivalent to an orange. When an equal number of oranges and apples a

Silicon Carbide (SiC) substrates are classified based on their quality and characteristics, which determine their suitability for various applications and market value. The following are the primary grades of SiC substrates:
