Coating and the substrate surface temperature of the coating would have a bad contraction stress, caused by cracking and peeling off the coating.

涂层与基体表面的温度差会使涂层产生收缩应力，引起涂层开裂和剥落。

Thus, the semi-insulating nitride semiconductor crystal substrate in which warpage is less and cracking is less likely can be obtained.

由此，能获得其中翘曲较少且较不可能发生破裂的半绝缘氮化物半导体晶体衬底。

The strippable film on the substrate has high attachment, no surface cracking and long service life.

本发明模仁的 离形膜附着性好，表面无裂纹，因此其使用寿命较长。
