Patent ID: 7615121

Claim:
A susceptor system for an apparatus of the type adapted to treat substrates and/or wafers, the susceptor system being 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 ) being constituted by at least one piece of electrically conducting material suitable for being heated by electromagnetic induction, the lower wall ( 3 ) being constituted by at least one piece of electrically conducting material suitable for being heated by electromagnetic induction, the right-hand side wall ( 4 ) being made in its entirety by at least one piece of inert, refractory material and preventing conduction of electrical current there through, the left-hand side wall ( 5 ) being made in its entirety by at least one piece of inert, refractory material and preventing conduction of electrical current there through, the right-hand side wall ( 4 ) and the left-hand side wall ( 5 ) each separating the upper wall ( 2 ) from the lower wall ( 3 ) SO that the or each piece of the upper wall ( 2 ) is electrically insulated from the or each piece of the lower wall ( 3 ), the walls ( 2 , 3 , 4 , 5 ) being included in the susceptor system.
