Inhibition of fluid flow instabilities in the melt by the axial magnetic field in Czochralski silicon crystal growth (AMCZ) is investigated precisely by a high-sensitivity striation etch in conjunction with temperature measurements. The magnetic field strength (B ) was varied up to 4.0 kG, incremented mostly in 0.5-kG/2.5-cm crystal length. The convection flow was substantially suppressed at B> 1.0 kG. A low oxygen level of 2-3 ppm and a high resistivity of 400 n cm is achieved in the AMCZ silicon crystals atB> 1.0 kG. Random striations at B = 0, characteristic of turbulent convection, assumed progressively a periodicity, indicative of oscillatory convection at 0.35
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
