Abstract:
1. An Al-based alloy sputtering target consisting of 2-4 at % Ni, 0.4-2 at % of a rare earth element selected from the group consisting of Nd, Y, and Dy, and the balance Al, wherein there are 5.0×10 wherein the amount of bending of the Al-base alloy sputtering target is 2 mm or less after holding at 250° C. for 1 hour, and wherein the Al-base alloy sputtering target is formed by spray forming with a nozzle diameter (φ) ranging from 3.0 to 5.5 mm and a gas pressure ranging from 0.6 to 0.9 MPa, wherein wherein the orientation of the Al-base alloy sputtering target is controlled by rolling at a total processing rate of at least 60% and a processing rate per pass of at least 5%.
