Abstract

We investigated the relationship between the formation of small grains and distribution of precipitates such as Si3N4 and SiON in a multicrystalline silicon ingot grown by the unidirectional solidification method. Si3N4 precipitate was mainly observed inside the small grain region, while SiON was mainly precipitated outside there. We found that SiON started to precipitate prior to formation of Si3N 4 precipitates. Therefore, precipitation of SiON prior to precipitation of Si3N4 plays a key role in the formation of small grains.
