  • Publication number: 20060269762
    Abstract: Disclosed are organic-compatible thin film processing techniques with reactive (such as Ti) layers for embedding capacitors into substrates. Hydrothermal synthesis allows direct deposition of high-k films with capacitance density of about 1 ?F/cm2 on organic substrates. This is done by reactively growing a high-k film from Ti foil/Ti-coated copper foil/Ti precursor-coated organic substrate in an alkaline barium ion bath. Alternatives may be used to address multiple coatings, low temperature baking, low temperature pyrolysis with oxygen plasma, etc. Sol-gel and RF-sputtering assisted by a reaction with the intermediate layer and a foil transfer process may be used to integrate perovskite thin films with a capacitance in the range of 1-5 ?F/cm2. Thermal oxidation of titanium foil/Ti-coated copper foil/Ti-coated organic substrate with a copper conductive layer is also a reactively grown high-k film process for integrating capacitance of hundreds of nF with or without using a foil transfer process.
