Abstract
A method and a device for igniting silicon rods outside a CVD-reactor. A silicon rod is disposed inside a chamber of a casing of an ignition device. At least one pair of contact electrodes applies a first voltage supplied by a transformer with an open circuit voltage sufficiently high to initialize a current flow in and ignite the silicon rod. Optionally, the silicon rod may be heated by a current flow and/or an external heating unit to a temperature within a predetermined range. The silicon rod is removed from the ignition device and may be exposed to a depositing process inside a CVD-reactor. The ignition of the silicon rod outside the CVD-reactor facilitates a new ignition for the depositing process.
