Abstract
In a crystal manufacturing method, first, a feedstock including a tapered tip portion is disposed above a crystal growth region. Then, a side surface of the tip portion is selectively heated and melted by radiant heat traveling diagonally upward while a shape of the tip portion is maintained, and the side surface of the tip portion is physically connected to an upper surface of the crystal growth region by a material melted from the side surface. In a crystal manufacturing apparatus, the radiant heat for melting the feedstock is radiated from an electric resistance heater.
