1、Designation: F 1513 99 (Reapproved 2003)Standard Specification forPure Aluminum (Unalloyed) Source Material for ElectronicThin Film Applications1This standard is issued under the fixed designation F 1513; the number immediately following the designation indicates the year oforiginal adoption or, in
2、the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers pure aluminum metal (unal-loyed) for use in evaporation s
3、ources and sputtering targets.This material is intended as a raw material for electronicapplications. The material is used as-supplied in some cases(for example, as e-beam evaporation sources). In other in-stances it may be remelted, alloyed, cast and processed by thepurchaser to make finished produ
4、cts (for example, sputteringtargets).1.2 This specification sets purity grade levels, physicalattributes, analytical methods, and packaging.1.3 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.2. Referenced Documents2.1 ASTM Sta

20、mits of the specified methods.12. Certification12.1 When required by the purchaser, a certificate ofanalysis/compliance that represents the finished material lotshall be provided for each lot by the supplier.12.2 The certificate of analysis/compliance shall state themanufacturers or suppliers name,
21、the suppliers lot number,the grade level (Section 4), impurity levels (Section 6), methodof analysis (Section 11), and any other information as agreedupon between the supplier and the purchaser.12.3 Impurity levels are to be reported in the certificate ofanalysis/compliance using actual analytical (
22、not “typical”)results for the material lot. All impurity levels, except uraniumand thorium, shall be reported in wt. ppm. Uranium andthorium are ordinarily controlled at very low levels in thismaterial and may be reported in parts per billion by weight (wt.ppb). Nondetected trace impurities shall be
