Method to protect internal components of semiconductor processing equipment using layered superlattice materials

Abstract:

This invention relates to apparatus and a method to protect the internal components of semiconductor processing equipment such as a plasma reactor or a reactive species generator against physical and/or chemical damages during etching and/or cleaning processes. Layered superlattice materials having three or more metal elements such as strontium bismuth tantalate (SBT) are used to form a protective barrier on the surfaces of the internal components of a reaction chamber.

Abstract(Chinese):

本发明涉及在蚀刻和/或清洁过程中保护诸如等离子体反应器或反应物种发生器的半导体加工设备的内部部件抵抗物理和/或化学损伤的装置和方法。使用具有三种或更多种金属元素的层状超晶格材料，例如钽酸锶钡（SBT），在反应室的内部组分的表面上形成保护屏障。
