  • Precursor composition, method for manufacturing precursor composition, method for manufacturing ferroelectric film, piezoelectric element, semiconductor device, piezoelectric actuator, ink jet recording head, and ink jet printer
    Publication number: 20050271823
    Abstract: To provide precursor compositions for forming ferroelectric, methods for manufacturing precursor compositions, and methods for forming ferroelectric films using precursor compositions, which have excellent composition controllability in a liquid phase method, and in which metal compositions such as lead can be reused. A precursor composition pertains to a precursor composition including a precursor for forming a ferroelectric, wherein the ferroelectric is expressed by a general formula of AB1-xCxO3, where an element A is composed of at least Pb, an element B is composed of at least one of Zr, Ti, V, W and Hf, an element C is composed of at least one of Nb and Ta, and the precursor includes at least the element B and the element C, and has an ester-bond in a part thereof.

  • Raw material solution, ferroelectric film, method for manufacturing ferroelectric film, piezoelectric element, piezoelectric actuator, ink jet recording head, and ink jet printer
    Publication number: 20050218437
    Abstract: By designing the structure of ferroelectric constituting elements in a raw material solution for a ferroelectric thin film, the crystallization temperature is lowered. A raw material solution forms the ferroelectric shown by a general formula of ABO3, and includes a sol-gel raw material, and a MOD raw material having a stoichiometric composition of at least an element B that is identical with the sol-gel raw material.

  • Method of synthesizing metal doped diamond-like carbon films
    Patent number: 6669996
    Abstract: A method of synthesizing metal doped carbon films by placing a substrate in a chamber with a selected amount of a metalorganic compound. An electron cyclotron resonance is applied to the chamber in order to vaporize the metalorganic compound. The resonance is applied to the chamber until a metal doped carbon film is formed. The metalorganic compound is preferably selected from the group consisting of an organic salt of ruthenium, palladium, gold or platinum.
