    摘要: Provided is a cylindrical ceramic sputtering target, which significantly reduces the occurrence of a crack, a chip, extraordinary discharge and a nodule. By filling a molten bonding material in a cavity defined by a cylindrical ceramic target material and a cylindrical base material, starting cooling the molten bonding material from its one end toward its other end in a cylindrical axial direction in sequence, and further filling the molten bonding material in the cavity during cooling, a cylindrical ceramic sputtering target is manufactured so as to be characterized in that as observed by an X-ray radiograph of the bonding material, the total area of portions where no bonding material exists is 10 cm 2 or less per 50 cm 2 of X-ray radiograph area, and the maximum area of the portions where no bonding material exists is 9 cm 2 or less.

    摘要: To provide a cylindrical sputtering target, whereby cracking during sputtering can be remarkably reduced.
    A cylindrical sputtering target, wherein a cylindrical target material made of ITO or AZO has a relative density of at least 90%; the angle between the grinding direction on its outer circumferential surface and a straight line parallel with its cylindrical axis (out of such angles, θ represents an angle between 0° and 90°) satisfies 45° πR/L (where R is an outside diameter of the cylindrical target material, and L is the length of the cylindrical target material); and the surface roughness Ra of the outer circumferential surface of the cylindrical target material is at most 3 µm.
