Latest Patents

Xia-Xi Zheng holds a patent for a MOCVD method for growing an InAlGaN/GaN heterostructure. This method involves sequentially growing a nitride nucleation layer, a GaN buffer layer, and an InAlGaN barrier layer on a substrate. A precursor gas containing silane is used to in-situ grow a SiNx protective layer on the InAlGaN barrier layer at a temperature of 950-1000° C. in the same reaction chamber. This innovative approach results in a SiNx/InAlGaN/GaN heterostructure with an ultrathin barrier layer, which is ideal for fabricating HEMT elements. The method also prevents oxidation and damage to the heterostructure by eliminating the need to take samples out of the reaction chamber.
