Abstract

PCTJP/043990 MAGNETIC MATERIAL SPUTTERING TARGET AND METHOD FOR 5 MANUFACTURING SAME Provided is a magnetic sputtering target which includes oxides having a melting point of 500°C or lower, and the magnetic sputtering target is characterized by an average number density of oxides having a grain size of 10 pm or more on a 10 sputter surface of the sputtering target is 5/mm 2 or less. The present invention addresses the problem of providing a sputtering target and a method for manufacturing the same, whereby the generation of particles or abnormal electric discharge caused by oxides in the sputtering target, particularly coarsely grown oxides, can be reduced. 15 Fig. 3 22
