Sputtering Targets (1)
As semiconductor devices continue to shrink in size and increase in density, demand Increases for high purity, low particle films such as wiring, gate electrode, and barrier metals.We draw on our proprietary technologies to meet these needs and to further apply these technologies to the high power sputtering target market.
-
a Particle levels and bottom
coverage are significantly
improved By controlling
the re-crystallization
and the orientation of the target -
We offer high quality
Ti-W targets with high density
and Low particles as a refiner
of high purity tungsten
-
We provide high purity and fine
grain size dielectric, PZT,
chalcogenide and BST sputtering
targets which are prepared by our
exellent powdering and sintering
technique, applicable to new non-volatile
memory such as FeRAM, PCRAM,
and thin film condensers.
-
High purity nickel and cobalt targets
have fine, homogeneous grain size and
low magnetic permeability.
Sputtering Targets (2)
Thin films are used in various fields of modern society. It is sputtering targets which are essential for the formation of thin films. Mitsubishi Materials Corporation supplies sputtering targets of every variety which are used in each field of semiconductor,LCD,disks for optical memory and magneto optical memory,sensor magnetic disk,functional glass,superconductor and so on as a general target manufacturer.
Semiconductor devices and recording media devices, which support today's information society, have especially made great progress. Our sputtering target is improves those technique and development by utilizing real demanded quality and speed.
We consider the sputtering target business to be the general business which integrate materials,film forming and evaluation.We are going to meet customer needs which become more and more complicated and sophisticated by reinforcing and encouraging the integration with the reinforcement of each basic technique.

반도체
We supply the targets corresponding to high purity, low particle and high sputtering power for each film forming of semiconductor devices which become to be higher-integration and finer more and more. We can also supply large-size targets corresponding to large-diameterizing of wafer (300mm).
Especially dielectric materials (high dielectrics and ferroelectrics) including those electrode materials provide the best materials for each thin film forming method putting MOCVD materials and sol-gel liquid together. In addition, we invest our energy in the development of materials for nonvolatile phase change memory for the next generation putting our technology of phase change materials which we improved with rewriting disks.
