6H-SiC ingots with diameters of 25-35 mm with flat natural surfaces have be
en grown by the Modified Lely method. Influence of the growth conditions an
d crucible geometry on the growth front shape and on the enlargement of the
seeds have been investigated. The developed growth process allows the grow
th of ingots under quasi-equilibrium conditions with and without enlargemen
t at a growth rate between 1-1.5 mm h(-1). (C) 1999 Elsevier Science S.A. A
