摘要： The invention discloses a method for forming a conductive polymer with an electrophoretic deposition cell, into porous anode for electrolytic capacitors. The conductive polymer is directly deposited on the oxide layer of the anode body. The electrolytic polymerized conductive polymer material form the cathode in solid electrolyte capacitors. The method allows low ESR capacitors to be produced. The invention provides a high yield and low cost industrial process with efficient materials utilization. The present invention successfully deposits particles from dispersion on continuous, highly insulating dielectric layers using electrophoretic deposition by use of EPD voltage near or above the anode dielectric formation voltage, where the anode body is positively biased relative to the EPD counter electrode, thereby allowing a current to be driven through the dielectric layer.

摘要： The present invention is a method of manufacturing high density interconnects, electrical passive components (such as resistors, capacitors, transmission lines and inductors) and circuits on dielectric carriers. The method comprises performing electrophoretic deposition (EPD) on a conductive substrate that has been previously prepared in such a way that electrochemical deposition is possible only on selected areas of said conductive substrate. The present invention is a method of forming a green film in the form of fine lines and passive electrical elements and circuits on a dielectric tape, and in particular, on a ceramic tape such as the LTCC. This method has the capability to produce features of smaller dimensions (and therefore improved resolution) cost effectively and with improved uniformity in the properties of said green film. The invention is also electrical passive components and circuits manufactured totally or partially by EPD on dielectric carriers and to devices using such components and circuits.

摘要： An improved method for depositing ferroelectric particles on a surface of a substrate to form films or stand-alone bodies. The improvement is based on electrophoretic deposition (EPD) of ferroelectric films by using a tri-functional phosphate ester additive having a concentration less than 10 volume percent in the EPD suspension, without the need for addition of a binder. The method includes preparation of the suspension by washing and dispersing ferroelectric particles, for example, commercially available PZT powder, in a polar solvent such as ethanol, followed by addition of the phosphate ester additive to the suspension, and an ultrasound treatment. The suspension is used in EPD of the ferroelectric particles on a prepared substrate. Following EPD, the green film is dried and sintered at high temperature. Visual and physical examination of stand alone and patterned PZT deposited films show excellent quality obtained in manufacturing a diversity of piezoelectric products, featuring exceptionally high green film uniformity, thickness distribution, and reproducibility to within +/- 2 microns for 20 micrometer film thickness. The phosphate ester additive functions by improving stabilization and control of suspension characteristics and properties during the electrophoretic migration process, and by improving desired dimensions, characteristics, and electrical properties of the deposited green film. Thin or thick ferroelectric films, either as stand alone products, or formed on geometrically demanding patterned or non-patterned substrates are produced by using the method. The improved method is applicable to different ferroelectric particulate materials and to different substrates used for manufacturing piezoelectric elements and devices, in a cost effective manner.
