電子氣體是半導體制造的關鍵，高純電子級二氧化碳在集成電路中尤為重要。新國標《GB/T43772-2024》對二氧化碳純度有嚴格要求。
?
國際半導體設備與材料組織（SEMI ）在2018年C3.57-0312中，對二氧化碳產(chǎn)品的純度要求要達到 99.999% 以上，雜質(zhì)限量在ppm級別。隨著集成電路行業(yè)的發(fā)展，我國新制定的國標《GB/T43772-2024 電子氣體 二氧化碳》中對二氧化碳品的純度要求已達到 5N以上，對氣體雜質(zhì)要求達1~5ppm，其中總硫要求低至10ppb

Electronic gases are crucial for semiconductor manufacturing, and high-purity electronic grade carbon dioxide is particularly important in integrated circuits. The new national standard GB/T43772-2024 has strict requirements for the purity of carbon dioxide.
According to the International Semiconductor Equipment and Materials Organization (SEMI) in C3.57-0312 of 2018, the purity requirement for carbon dioxide products must be above 99.999%, with impurity limits at the ppm level. With the development of the integrated circuit industry, the purity requirement for carbon dioxide products in China's newly formulated national standard "GB/T43772-2024 Electronic Gas Carbon Dioxide" has reached 5N or above, and the requirement for gas impurities is 1-5ppm, with a total sulfur requirement as low as 10pppb
This document specifies the technical requirements, sampling, testing methods, inspection rules, labeling, packaging, transportation, storage, and safety information requirements for carbon dioxide.
This document applies to electronic carbon dioxide prepared by purifying high-purity carbon dioxide.
