Ferroelectric materials and Piezoelectric materials


PZT type materials which have properties of Ferroelectric and Piezoelectric effect have been applied to a wide range of fields, e.g. FeRAM (Ferroelectric Random Access Memory), MEMS (Micro Electro Mechanical Systems) sensor and inkjet device. We produce and sell various kinds of film formation materials such as MOD coating materials, MOCVD materials and sputtering targets. We can deal with not only the composite oxides such as PZTs and BSTs but also customized products.

CVD(Chemical Vapor Deposition)

  We have a lot of experiences and achievements about products (synthesis, refining, and analysis) and cylinders (cleaning, maintenance and design). We can promptly prepare any cylinder from small size for development to large size for mass production.

PVD(Physical Vapor Deposition)

We are dealing with a full range of size, control of purity/gas amount/crystal design, manufacturing of backing plate, bonding and making parts of equipment.
We have a product line of standard composition, but it is possible to make an adjustment of that according to your demands.
