Abstract
A method of growing semiconductor crystals including inserting a single crystal seed (14) of a semiconductor material into a melt (12) and pulling the seed (14) at a first rate to gradually grow an elongated, single crystal first neck (15), altering the pulling rate to a second rate, slower than the first rate, to grow a shoulder (17) on the first neck (15) with a diameter greater than the first neck (15), continuing to pull at the second rate to form a second neck (18) with a diameter equal to the diameter of the shoulder (17), and altering the pulling rate to a third rate, slower than the second rate, to grow a single crystal elongated body (20) of the semiconductor material.
