STrained layers and strain depth profile of high dose As ion implanted (100) si wafer annealed at various temperatures have been investigated by means of X-ray double crystal diffractometry (X-ray DCD). The results obtained by x-ray rocking curve analysis showed a defect layer at the original amorphous /crystalline interface of 1400$\AA$ depth. In addition arsenic ion concentrtion profiles and defect distributions in depth were obtained by the SIMS and TRIM -code simulation . the positive strain depth profile determined from the rocking curve analysis were only presented under 0.14 $\mu$m from the surface for samples ananelaed at $600^{\circ}C$. The results was shown that the thickness of amprphous layer is 0.14 $\mu$m indirectry, and it was good agreement with the TRIM -Code simulation. Additionally, it could be thought that the positive strain have been affected residual intersitial atoms under the amorphous/crystalline interface formed by ion implantation.
