    • A method for forming iii-nitrides semiconductor on the semiconductor substrate is provided to reduce the junction density by improving a crack on the surface of GaN. A crystal direction silicon semiconductor substrate is used as a growth substrate, and the surface nitridation water is removed by using HF.
