Abstract
An electrical resistance heater for use in a crystal puller used for growing monocrystalline ingots according to the Czochralski method comprises a heating element sized and shaped for placement in the housing of the crystal puller for radiating heat within the housing. The heating element has heating segments arranged in a generally side-by-side relationship and electrically connected together. Each heating segment comprises a web and a flange projecting outwardly from the web in non-coplanar relationship therewith. This reduces the cross-sectional area of the heating segment for increasing the electrical resistance and power output of the heater while providing desired structural rigidity.
