摘要: A microwave plasma treatment apparatus comprises a plurality of auxiliary magnets arranged around the periphery of a plasma formation chamber. A plurality of auxiliary magnets are disposed along the circumference of the plasma formation chamber while a plurality of auxiliary magnets may also be arranged in the axial direction of the plasma formation chamber. Also, the magnetic poles of every auxiliary magnet are respectively reverse in polarity to the adjoining magnetic poles of an auxiliary magnet(s) disposed adjacent thereto either along the circumference of the plasma formation chamber or in the axial direction thereof. This enables the whole high-density plasma to be substantially uniform throughout the inside of the plasma formation chamber.

摘要: [Objection of the invention]An ion beam generator, a thermal distortion in a grid assembly is reduced. [Structure to solve the objection]Thermal expansion coefficients αP, αM and αG, for a sidewall (1A) of a discharge chamber, mounting platform (40) and extraction grid electrode assembly (20) are selected to have a relation: αP>αM≧αG. For example, the material of discharge chamber sidewall is stainless steel o aluminum, the material of grids is Mo, W or C and the material of platform is Ti or Mo.
