Abstract
Oxygen and oxygen-related centers in cast multicrystalline silicon (mc-Si) have been investigated. The concentration profile and the map of oxygen in me-Si revealed that oxygen with higher concentration occurred at the bottom area and at the edge area of me-Si ingots. The oxygen concentration and it s profile were partly dependent on the cooling progress. It was found that the thermal donors related to oxygen were generated in the area of higher o xygen concentration. The concentration of thermal donors can reach to 1 x 1 0(14)/cm(3). Meanwhile, as-grown oxygen precipitates were observed at the b ottom of mc-Si. (C) 2000 Elsevier Science B.V. All rights reserved.
