FORFARANDE OCH ANORDNING FOR SMELTNING OCH FORANGNING AV KISEL

摘要

A high-purity method of forming a silicon melt utilizes a solid silicon body which is drilled to provide bores into which electrodes are inserted. The electrodes preferably are also of silicon and an electric arc-current is passed through the electrodes to generate an arc which melts out the body to define a cavity therein containing the melt. The melt may be used for the drawing of a silicon bar or for the deposition of silicon in vapor form from the melt upon a substrate in a vacuum chamber.
