- Silicon single crystal manufacturing system silicon single crystal manufacturing method, and silicon single crystal
- the present invention relates to a design system of optimum manufacturing conditions, a method of manufacturing a silicon single crystal, and a silicon single crystal for efficiently producing a silicon single crystal having few crystal defects at a high yield.
- CZ method silicon single crystals manufactured by the Czochralski method
- D Laser scattering Tomography Defect
- COP Crystal urigmate d Particle
- vacancy-type point defect called vacancy (hereinafter sometimes abbreviated as V) that is incorporated into a silicon single crystal during crystal growth, and an interstitial defect.
- V vacancy-type point defect
- interstitial defect The factors that determine the concentration of each of the interstitial silicon-type point defects, called sial silicon (Interstitial—Si, sometimes abbreviated as I below), are generally known.
- the V region is a region where there are many voids generated by insufficient force of silicon atoms
- the I region is an aggregate of silicon atoms generated due to the presence of extra silicon atoms.
- This is a region with a large number of dislocation loop clusters, and between the V region and the I region there is a neutral-neutral (hereinafter sometimes abbreviated as N) region with few atoms.
- N neutral-neutral
- the concentration of these two point defects is determined by the relationship between the pulling rate (growth rate) of the crystal in the CZ method and the temperature gradient G near the solid-liquid interface in the crystal.
- Defect force called Oxidation Induced Stacking Fault (Oxidation Induced Stacking Fault)
- OSF ring ring shape
- growth-in defects are classified, for example, when the growth rate is relatively high, such as about 0.6 mmZmin or more, FPD, LSTD, Grown-in defects such as COP exist at high density throughout the crystal diameter direction, forming a V region.
