Abstract
A pull head of a Czochralski crystal puller is mounted on a receiving chamber via a mounting apparatus that provides for pull head alignment. The mounting apparatus has a top plate for secured to the receiving chamber, a bottom plate for supporting the pull head, and an adjustment mechanism disposed on the bottom plate for adjustably positioning the top plate with respect to the bottom plate, and, thus, the puller head with respect to the receiving chamber. Accordingly, the pull head can be adjusted with respect to the crucible rotation axis and can be positioned in order to insure that its rotation axis is substantially vertical.
