Abstract: A system for growing silicon carbide crystals on substrates is described and comprises a chamber (1) which extends along an axis, wherein the chamber (1) has separate input means (2, ;) for gases containing carbon and for gases containing silicon, substrate support means (4) disposed in a first end zone (ZI) of the chambe, exhaust output means (5) disposed in the vicinity of the support means (4), and heating means adapted for beating the chamber (1) to a temperature greater than 1800° C.?; the input means (2) for gases containing silicon are positioned, shaped and dimensioned in a manner such that the gases containing silicon enter in a second end zone (Z2) of the chamber; the input means (3) for gases containing carbon are positioned shaped and dimensioned in a manner such that the carbon and tire silicon come substantially into contact in a central zone (ZC) of the chamber remote both from the first end zone (ZI) and from the second end zone (Z2).

Abstract: A support system (1) for an apparatus of the type able to treat substrates and/or wafers is described, said system comprising a fixed base element (10) having a substantially flat surface in which a substantially cylindrical seat (11) with a substantially flat bottom is formed, and a movable support element (20) having a substantially disc-shaped form, being housed inside the seat (11), being able to rotate about the axis of the seat (11) and having a substantially flat upper side provided with at least one cavity (21) for a substrate or wafer and a substantially flat bottom side; one or more passages (12) for one or more gas flows are provided, which passages (12) emerge inside the seat (11) in directions which are inclined and preferably skew with respect to its axis, in such a way as to lift and rotate the support element (20).

Abstract: The present invention relates to a susceptor system for an apparatus of the type adapted to treat substrates and/or wafers; the susceptor system is provided with a cavity (1) which acts as a chamber for the treatment of the substrates and/or wafers and which extends in a longitudinal direction and is delimited by an upper wall (2), by a lower wall (3), by a right-hand side wall (4), and by a left-hand side wall (5); the upper wall (2) is constituted by at least one piece of electrically conducting material suitable for being heated by electromagnetic induction; the lower wall (3) is constituted by at least one piece of electrically conducting material suitable for being heated by electromagnetic induction; the right-hand side wall (4) is constituted by at least one piece of inert, refractory and electrically insulating material; the left-hand side wall (5) is constituted by at least one piece of inert, refractory and electrically insulating material; the piece of the upper wall (2) is thus electrically well i

Abstract: The present invention relates to a susceptor system for an apparatus for the treatment of substrates and/or wafers, provided with a treatment chamber (1) delimited by at least two walls and with at least one heating solenoid (9); the susceptor system comprises at least one susceptor element (2, 3) delimited by an outer surface and made of electrically conducting material suitable for being heated by electromagnetic induction; the susceptor element (2, 3) is hollow; a first portion of the outer surface of the susceptor element (2, 3) is suitable for acting as a wall of the treatment chamber (1); a second portion of the outer surface of the susceptor element (2, 3) is suitable for being disposed close to the heating solenoid (9).
