Abstract
A sputtering target that consists essentially of a continuous matrix of Ti-W phase, Ti phase having a particle diameter of 50 .mu.m or less distributed in the matrix, and a W phase having a particle diameter of 20 .mu.m or less also distributed in the matrix. Preferably the target contains aluminum in the range of 1 ppm or less. The target has high density and a low impurity content, which reduces the generation of particles from the target when it is used for sputtering. A method of manufacturing the sputtering target is also disclosed.
