摘要: Abstract Effect of annealing up to 1400 K under argon pressure 1.2 GPa (HT-HP treatment) on silicon implanted with hydrogen (Si:H), oxygen (Si:O) and silicon-on-insulator (SOI) structure was investigated by X-ray methods transmission electron microscopy (TEM). The results obtained for the HT-HP treated samples were compared that annealed at atmospheric (10 5 Pa). For Si:H Si:O treatment influences strain state Si top layer much stronger than pressure. prohibits diffusion towards surface region. as-bonded SOI structures indicated presence defects. mosaic-like high defect concentration observed also 1370 K–1.2 GPa, while 10 Pa resulted in improved perfection layer.
