| Outline of Final Research Achievements |
Thermal annealing have been employed for the interface alloying between semiconductor and metal contact. Similar process trying to be applied also to wide bandgap semiconductors. However, extreme high temperature annealing is needed due to the strong bond peculiar to the wide bandgap semiconductors. Because of its high temperature environment, the high temperature annealing lead to the bad effects such as the restriction of the devices processes.
We tried to anneal the interface between metal and wide bandgap semiconductors by using the laser irradiation. It was found that the atomic migration was induced by the femtosecond laser irradiation associated with the relatively low temperature thermal annealing. In addition, similar phenomena was observed also by the continuous wave laser irradiation.
