METHODS FOR PRODUCING A MONOCRYSTALLINE INGOT BY HORIZONTAL MAGNETIC FIELD CZOCHRALSKI

Methods for producing monocrystalline silicon ingots by horizontal magnetic field Czochralski are disclosed. During growth of the neck and/or growth of at least a portion of the crown, a magnetic field is not applied to the neck and/or crown or a relatively weak magnetic field of 1500 gauss or less...

More Information
Summary:Methods for producing monocrystalline silicon ingots by horizontal magnetic field Czochralski are disclosed. During growth of the neck and/or growth of at least a portion of the crown, a magnetic field is not applied to the neck and/or crown or a relatively weak magnetic field of 1500 gauss or less is applied. A horizontal magnetic field (e.g., greater than 1500 gauss) is applied during growth of the ingot main body.
