摘要
On the reliability evaluation, the phenomenon of surface roughness on the Al substrate surface on power device is confirmed. This surface roughness is generated by cyclic thermal stress under thermal cycle test. In this study, the surface roughness characteristic after thermal cycle test is executed to DBA substrate and the generating mechanism was investigated.
