6inch LED Sapphire substrate

Product Description

Sapphire substrates belong to one of the most significant aspects of the construc-tional application of this material. They are used for epitaxy of semiconductor films such as Si, GaN, AlGaN, and for making integrated circuits.

Sapphire substrates are inert, work at high temperatures and mechanical loads, and can be obtained in large size. Therefore, they are used even in those cases when the lattice parameters do not completely coincide with the parameters of heteroepitaxial structures. 


Although there are lots substrates which are regarded as potential materials to replace sapphire substrate, it is still dominated in the substrates (for GaN LED growth) market, because of its reasonable price and relatively low mismatch.

Zhongju is capable of processing substrates according to customer needs. Currently, our sapphire substrate productions ranges from 2 to 12 inches with high quality and accurate orientation.
