The present invention is to provide a crucible for the growth of silicon crystal, which can enhance the productivity, yield and quality of crystal in the process of silicon crystal growth by Czochralski method, and a silicon crystal growing method by Czochralski method using said crucible. <??>A crucible for the growth of silicon crystal by Czochralski method having an inner bottom surface, the profile of which has at least a raised portion symmetrical about the rotary axis of the crucible wherein the periphery of the raised portion is positioned at a distance of from 0.4 to 1.2 times the radius of crystal to be grown from the rotary axis and the height of the raised portion is from not smaller than 7% to not greater than 100% of the radius of crystal to be grown. |
