X-Ray Section Topography of Hydrogen Precipitates in Silicon

  • S.F. Cui (a1), G.S. Green (a1) and B.K. Tanner (a1)


Spherical strain centres produced by annealing of silicon crystals grown in a hydrogen atmosphere have been studied by X-ray section topography. Excellent agreement has been found between experimental images and those simulated by numerical solution of Takagi's equations. The contrast differences between images in four reflections are examined and recommendations made as to the most suitable conditions for the study of oxygen precipitates in processed silicon wafers.
