Oxygen precipitation occurs along growth striations in Czochralski-grown (CZ) silicon single crystal. Interstitial oxygen (Oi) striations in various CZ and horizontal magnetic field Czochralski-grown (HMCZ) silicon single crystals were studied with a

Growth striations in CZ and MCZ silicon wafers were studied by the striation-etching method, spreading resistance measurements and the micro-FTIR mapping method. Microvariations in oxygen concentration were successfully measured using the micro-FTIR

A method for revealing point defects in silicon single crystals has been investigated. D or A defects could be revealed by a preferential etching technique using Secco's etchant. Wedge-shaped flow patterns and etch pits were recognised in the D and A

We investigated phenomena of oxygen precipitation nonuni-formity along crystal growth axis due to different thermal histories during CZ crystal growth. The oxygen precipitation process employed in this paper was two-step thermal treatments consisting

We investigated the effect of D-defect in CZ silicon single crystals on the oxygen precipitation by two-step thermal treatments consisting of the first annealing in nitrogen ambient at 1073K and the second annealing in dry oxygen ambient at 1273K. Th

We investigated phenomena of oxygen precipitation in silicon single crystals by two kinds of thermal treatment, supposing a CMOS fabrication process. The one consisted of the first annealing at 1123K for 4 hrs and the second annealing at 1423K for 16
