Abstract:
An apparatus for fabricating a semiconductor device comprising:a plasma torch having a hollow convey tube of which one end portion is made of a conductor so as to function as an inner electrode, for injecting plasma generating gas through one end portion, conveying and spraying a plasma frame through the other end portion; an energy applying unit for applying a microwave to the gas conveyed through the convey tube and adds an energy thereto; an outer electrode for surrounding the other end portion of the convey tube and its extended portion coaxially; an insulation tube positioned between the convey tube and the outer electrode for electrically insulating the other end portion of the convey tube and the outer electrode and surrounding a part of the convey tube coaxially; a power source for applying a voltage to the inner electrode and the outer electrode; a suscepter installed facing the plasma frame sprayed from the plasma torch; a suscepter moving unit for moving the suscepter in the vertical and horizontal directions to the other end portion of the convey tube; and a reactive chamber for surrounding the other end portion of the convey tube and the suscepter and defining a reactive space.
