摘要

The behavior of flow pattern defects (FPDs) in as-grown and RTA treated heavily Sb-doped wafers in the atmosphere of H_2 was investigated in this paper. The experimental results showed that FPDs density in heavily Sb-doped wafers was largely higher than that in B-doped wafers. The density of FPDs in heavily Sb-doped as-grown wafers was 17.5X10~6/cm~3, but the density of FPDs in lightly B-doped grown-in wafers was only 4.8X10~6/cm~3. After annealed with rapid thermal anneal (RTA) at 1150℃ for 10 min, the FPDs density in Sb-doped wafers decreased sharply. It became to 0.51 X 10~6/cm~3, and the density of FPDs in lightly B-doped grown-in wafers became to 0.41 X 10~6/cm~3. It attributed to that heavily doping Sb increased vacancy concentration and doping B decreased vacancy concentration. After annealed, the low concentration of oxygen and the out-diffusion oxygen accelerated the annihilation of void in Sb-doped wafers.
