Abstract:
A semiconductor device fabricating equipment using radio frequency energy, comprising:a housing having an upper electrode part in an upper portion thereof, the upper electrode applying the radio frequency energy, said housing including a ledge located between a top and bottom thereof extending from an inner wall of said housing to an interior of said housing; a chuck assembly which applies the radio frequency energy, fixes a provided wafer, and is installed so as to ascend and descend, opposite to the upper electrode part, inside the housing; a baffle plate which is fixed to an inner wall of the housing so that an inner side edge portion of said baffle plate is positioned adjacent to a side wall of the chuck assembly with a given distance therebetween, wherein the baffle plate is installed on and is supported by the ledge; a shield installed on the ledge, said shield having a tubular shape closely covering an inner wall of the housing; a tubular shaped liner extending down from the ledge of said housing and covering a surface of an inner wall of the housing, said liner having a bent upper end portion extending on the ledge, said baffle plate being positioned to be closely supported by the bent upper end portion of the liner, and said shield being installed in a form pressurizing and fixing an outer edge portion of the baffle plate; and a fastening instrument fastening the shield, the upper end portion of the liner, and the baffle plate on the ledge of the upper housing by piercing through them from an upper side thereof.
