摘要： A method for producing a semiconductor device having semiconductor layers of SiC with at least three doped layers on top of each other, comprises the steps of growing a first semiconductor layer of SiC; implanting an impurity dopant into the first layer to form a second doped surface layer as a sub-layer therein, the second doped surface layer being surrounded, except for the top surface thereof, by the first semiconductor layer; and epitaxially growing a third semiconductor layer of SiC on top of the second layer of SiC and regions of the first layer adjacent thereto to totally bury the second semiconductor layer. The impurity dopant implanted into the first semiconductor layer is of a first conductivity n or p type, and the first semiconductor layer being doped with a second, opposite conductivity type, so as to form a pn-junction at the interface between the first and second layers.

摘要： A device for epitaxially growing objects by Chemical Vapour Deposition on a substrate (1) comprises a susceptor (4) having a room (6) for receiving the substrate and means (9) for heating the susceptor and thereby the substrate and a gas mixture to be fed to the substrate for said growth. The substrate is arranged close to a first susceptor wall part (7) at least partially delimiting said room. Said heating means is arranged to heat the susceptor to a higher temperature of at least a second wall part (5) delimiting said room thereof and located substantially opposite to said first wall part than the temperature of the first wall part for obtaining a temperature gradient from said second wall part to the substrate and radiative heating thereof by said second wall part. (FIG. 1).
