Abstract (en)

[origin: EP1249521A1] The growth of a silicon carbide single crystal comprises growing a SiC single crystal on a seed crystal comprising a SiC single crystal at an angle alpha (20 [deg] less than alpha less than 60 [deg]) to the {0001} surface and at an angle beta of = 15[deg] of the vector obtained by projecting the normal vector onto the {0001} surface and the (11-20) direction. An independent claim is also included for a silicon carbide single crystal grown by this method.
