20110086213 | METHOD OF PRODUCING A SILICON CARBIDE BULK SINGLE CRYSTAL WITH THERMAL TREATMENT, AND LOW-IMPEDANCE MONOCRYSTALLINE SILICON CARBIDE SUBSTRATE - A silicon carbide bulk single crystal is produced at a growth temperature of up to 2200° C. by sublimation growth and is subjected to thermal aftertreatment after the sublimation growth. The bulk single crystal is brought to an aftertreatment temperature that is higher than a growth temperature. Very low-stress and low-dislocation SiC substrates can be produced from such a SiC bulk single crystal, the substrates additionally having a particularly low electrical resistivity. The SiC bulk single crystal is positioned within an SiC powder before the thermal aftertreatment and it is completely surrounded by the SiC powder during the thermal aftertreatment. | 04-14-2011 |
20130171402 | PRODUCTION METHOD FOR AN SIC VOLUME MONOCRYSTAL WITH A HOMOGENEOUS LATTICE PLANE COURSE AND A MONOCRYSTALLINE SIC SUBSTRATE WITH A HOMOGENEOUS LATTICE PLANE COURSE - A method is used for producing an SiC volume monocrystal by sublimation growth. Before the beginning of growth, an SiC seed crystal is arranged in a crystal growth region of a growth crucible and powdery SiC source material is introduced into an SiC storage region of the growth crucible. During the growth, by sublimation of the powdery SiC source material and by transport of the sublimated gaseous components into the crystal growth region, an SiC growth gas phase is produced there. The SiC volume monocrystal having a central center longitudinal axis grows by deposition from the SiC growth gas phase on the SiC seed crystal. The SiC seed crystal is heated substantially without bending during a heating phase before the beginning of growth, so that an SiC crystal structure with a substantially homogeneous course of lattice planes is provided in the SiC seed crystal. | 07-04-2013 |
20130171403 | PRODUCTION METHOD FOR AN SIC VOLUME MONOCRYSTAL WITH A NON-HOMOGENEOUS LATTICE PLANE COURSE AND A MONOCRYSTALLINE SIC SUBSTRATE WITH A NON-HOMOGENEOUS LATTICE PLANE COURSE - A method is used for producing an SiC volume monocrystal by sublimation growth. During growth, by sublimation of a powdery SiC source material and by transport of the sublimated gaseous components into the crystal growth region, an SiC growth gas phase is produced there. The SiC volume monocrystal grows by deposition from the SiC growth gas phase on the SiC seed crystal. The SiC seed crystal is bent during a heating phase before such that an SiC crystal structure with a non-homogeneous course of lattice planes is adjusted, the lattice planes at each point have an angle of inclination relative to the direction of the center longitudinal axis and peripheral angles of inclination at a radial edge of the SiC seed crystal differ in terms of amount by at least 0.05° and at most by 0.2° from a central angle of inclination at the site of the center longitudinal axis. | 07-04-2013 |
20130305983 | Physical Vapor Transport Growth System For Simultaneously Growing More Than One SIC Single Crystal and Method of Growing - The present invention relates to a configuration and in particular a physical vapor transport growth system for simultaneously growing more than one silicon carbide (SiC) bulk crystal. Furthermore, the invention relates to a method for producing such a bulk SiC crystal. A physical vapor transport growth system for simultaneously growing more than one SiC single crystal boule comprises a crucible containing two growth compartments for arranging at least one SiC seed crystal in each of them, and a source material compartment for containing a SiC source material, wherein said source material compartment is arranged symmetrically between said growth compartments and is separated from each of the growth compartments by a gas permeable porous membrane. | 11-21-2013 |
