1、Designation:D512713(Reapproved 2018)Standard Guide forUltra-Pure Water Used in the Electronics andSemiconductor Industries1This standard is issued under the fixed designation D5127;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the
2、year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide provides recommendations for water qualityrelated to electronics and semiconductor-industry manufactur-i
3、ng.Seven classifications of water are described,includingwater for line widths as low as 0.032 m.In all cases,therecommendations are for water at the point of distribution(POD).1.2 Water is used for washing and rinsing of semiconductorcomponents during manufacture.Water is also used for clean-ing an
4、d etching operations,making steam for oxidation ofsilicon surfaces,preparing photomasks,and depositing lumi-nescent materials.Other applications are in the developmentand fabrication of solid-state devices,thin-film devices,com-munication lasers,light-emitting diodes,photo-detectors,printed circuits
5、,memory devices,vacuum-tube devices,orelectrolytic devices.1.3 Users needing water qualities different from those de-scribed here should consult other water standards,such asSpecification D1193 and Guide D5196.1.4 This standard does not purport to address all of thesafety concerns,if any,associated
6、with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized p
