T/ICMTIA CM0035-2023 半导体硅材料制程装置用密封垫片

半导体材料提纯作为发展半导体器件的重要基础。由于大规模和超大规模集成电路的工艺要求,为得到N12级高纯度的硅材料，原料和中间体的高纯度和生产环境的高洁净度成为影响产品质量的一个突出问题。极微量的杂质混入对半导体的特性和芯片的良率均会造成极其严重的影响。因而在半导体材料和元件生产过程中对杂质必须进行严格控制。 垫片作为螺栓法兰密封组合装置中重要的组成部分，它的密封性能、可靠性和清洁度也同样影响着制程的稳定性和产品质量。密封垫片是半导体硅材料行业得到广泛应用且不可或缺的基础件，但国内外一直没有对用于制造半导体硅材料工艺装置和管道上的密封垫片作出明确的技术要求规范，如密封垫片的类型、质量要求、性能参数、清洁度要求等。 为了与现行行业相适应，也避免因垫片质量影响成品质量，特编制本文件。 本文件旨在确立半导体硅材料制程装置用密封垫片设计、制造、性能、选用所必须的要求。

It is also possible to have seals of irregular cross sections, or made of polymers which, due to their nature, or not conducive to a high-strength splice, although they will perform satisfactorily in their intended application. 1.3 Seals are exposed in service to a wide variety of media at various temperatures. The effect of such media on the spliced area must be considered. Details of the test procedures to evaluate the effect of the media shall be agreed upon by the purchaser and seller as part of the purchase contract. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.
