发明名称 Al-BASED ALLOY SPUTTERING TARGET AND Cu-BASED ALLOY SPUTTERING TARGET
摘要 <P>PROBLEM TO BE SOLVED: To provide a technique capable of improving a film forming speed in pre-sputtering and in the following sputtering to a substrate or the like using an Al-based alloy sputtering target or a Cu-based sputtering target and also suppressing sputtering failure such as a splash. <P>SOLUTION: When the total area rate of crystal orientations <001>&plusmn;15&deg;, <011>&plusmn;15&deg;, <111>&plusmn;15&deg;, <112>&plusmn;15&deg; and <012>&plusmn;15&deg; in the normal direction of the sputtering face in the depth within 1 mm from the outermost surface of the Al-based alloy or the Cu-based alloy sputtering target is defined as a P value, the sputtering target satisfies the requirement of the following (1) and/or (2), wherein (1) the area rate PA of <011>&plusmn;15&deg; with respect to the P value is 40% or less, and (2) the total area rate PB of <001>&plusmn;15&deg; and <111>&plusmn;15&deg; with respect to the P value is 20% or more. <P>COPYRIGHT: (C)2012,JPO&INPIT
