Webfor GaN epitaxial growth are approximately 2×10-6/°C dif-ferent from GaN in the thermal expansion coefficient. Therefore, thermal stress after cooling from the high tem-perature of the growth of thick GaN crystal caused large bending and cracks. It was difficult to obtain the GaN crys-tal for substrates because many cracks were confirmed in Webcommon, the CTE values used for GaAs should also be used with GaN devices. Epoxies cure at temperatures of 100 °C to 200 °C, which lessens the impact of high temperatures …
