    摘要: A refractory metal silicide target is characterized by comprising a fine mixed structure composed of MSi2 (where M: refractory metal) grains and Si grains, wherein the number of MSi2 grains independently existing in a cross section of 0.01 mm2 of the mixed structure is not greater than 15, the MSi2 grains have an average grain size not greater than 10 &mgr;m, whereas free Si grains existing in gaps of the MSi2 grains have a maximum grain size not greater than 20 &mgr;m. The target has a high density, high purity fine mixed structure with a uniform composition and contains a small amount of impurities such as oxygen etc. The employment of the target can reduce particles produced in sputtering, the change of a film resistance in a wafer and the impurities in a film and improve yield and reliability when semiconductors are manufactured.
