Edge-defined film-fed growth or EFG was developed for sapphire growth in the late 1960s by Harold LaBelle and A. Mlavsky at Tyco Industries. A shaper (also referred to as a die) having dimensions approximately equal to the crystal to be grown rests above the surface of the melt which is contained in a crucible. Capillary action feeds liquid material to a slit at the center of the shaper. When a seed crystal is touched to the liquid film and raised upwards, a single crystal form…
