Abstract: The present invention relates to a reaction chamber (1) for an epitaxial reactor, provided with walls delimiting an inner cavity (10), specifically a lower wall (3) and an upper wall (2) and at least two side walls (4,5); the lower wall (3) and the upper wall (2) have different configurations and/or are made of different materials; this allows the lower wall (3) to be heated to a higher temperature than the upper wall (2). The present invention also relates to a method for heating a reaction chamber.

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).
