摘要:
A sputtering target formed of a refractory metallic silicide having a composition MSi.sub.x including a mixture composition of an MSi.sub.2 phase in the form of particles (M: at least one refractory metal selected from a group consisting of W, Mo, Ti, Zr, Hf, Ni and Ta), and an Si phase provided as a matrix phase. Interface layers having a predetermined thickness are formed at the interfaces between the MSi.sub.2 phase and the Si phase. The value X in the composition formula MSi.sub.x is set to a range of 2.0 to 4.0, and the thickness of the interface layers formed between the MSi.sub.2 phase and the Si phase, the dispersion of the composition, the density ratio of the target, the electrical resistivity of the Si phase and the surface roughness are set to predetermined values. An uniform high-quality thin film in which a composition distribution is uniform can be manufactured stably by using this target.

Three magnetic field generating coils on the distal end side of the shape detection probe are provided in the curvable portion, and the first coil at the leading end position is placed at the position corresponding to the leading end curvable piece, whereas the third coil at the position corresponding to the trailing end curvable piece. Further, the second coil is placed at a middle position between the leading end curvable piece and the trailing end curvable piece in the curvable portion. With this structure, the accuracy of detecting the shape of the curvable portion can be improved, and the production cost of the system as a whole can be lowered.

This is a highly purified metal comprising one metal selected from the group consisted of titanium, zirconium and hafnium. The highly purified metal has an Al content of not more than 10 ppm. It also has an oxygen content of more than 250 ppm, each of Fe, Ni and Cr contents not more than 10 ppm and each of Na and K contents not more than 0.1 ppm. The highly purified metal is obtained by either purifying crude metal by the iodide process or surface treating crude metal to remove a contaminated layer existing on the surface thereof and then melting The surface treated material with electron bean in a high vacuum.

According to the present invention, metal silicide grains are coupled with each other in a linked manner so as to provide a metal silicide phase, and Si grains forming a Si phase are dispersed in the gaps of the metal silicide phase discontinuously so as to provide a mixed structure of a sputtering target of high density and containing carbon at a rate less than 100 ppm. Because of the high density and high strength of the target, generation of particles at the time of sputtering can be reduced, and because of the reduced content of carbon, mixing of carbon in a thin film formed by the sputtering can be prevented.

A resin-sandwiched metal laminate, a process and apparatus for producing the same and a process for producing a resin film for the resin-sandwiched metal laminate are disclosed. The laminate comprises a pair of face and back metal sheets and a resin layer and is capable of passing electricity between the face and back metal sheets, the resin layer being composed of electroconductive filler-containing resin regions at the side edges of the resin layer in the width direction of the metal sheets and an electroconductive filler-free resin center region provided between the electroconductive filler-containing resin regions at the side edges.
