Note (General): 出版タイプ： NA
In order to choose a crucible material for liquid Si diffusion experiments, a Boron Nitride (BN) and Pyrolytic Boron Nitride (PBN) were examined. The Si sample was heated in a BN and a PBN crucible, and the concentrations of B and N were analyzed. The concentration of B amounted to 5-8 x 10(exp 19) atoms/cc even after the sample was held at just above the melting point (1713 K) for a short period (10 minutes). N concentration was about 2 x 10(exp 17) atoms/cc, that is 2 orders smaller than B concentration. The reaction of the Si sample to BN or PBN crucible was not observed.
