    Abstract: A solder paste composition used in a solder precoating method of forming solder bumps by forming a dam around electrodes on a substrate, filling a solder paste composition on the electrodes within opening parts surrounded by the dam, and heating the solder paste composition filled, so that solder is adhered to the surfaces of the electrodes. The solder paste composition contains solder powder, which is of a particle size distribution in which particles having a particle size of below 10 μm are present 16% or more, and a sum of the particles having a particle size of below 10 μm and particles having a particle size of 10 μm or more and below 20 μm is 90% or more. This enables to suppress occurrence of bump defects, and form solder bumps of a uniform height with a high yield by a solder precoating method using the dam.

    Abstract: An interconnection substrate includes: an interconnection layer region where at least a first conductor layer and a second conductor layer are vertically stacked in that order on a substrate, with the first conductor layer and second conductor layer containing conductive particles and a binder, wherein the first conductor layer and second conductor layer stacked in the interconnection layer region have conductive particles different in average particle size from each other. As a result, only an intended region can have low resistance.

    Abstract: Spherical solder drops having precise and accurate shape are formed by an ejection device and solidified to form solder balls for making solder pastes. The diameters of the solidified solder balls are determined by an excitation signal applied to the ejection device and changes in the diameter of the orifice in the ejection device. A solder paste is produced by mixing solidified solder balls of a single diameter or a combination of several different diameters with a carrier.

    Abstract: The method for metallizing the surface of dielectric materials according to the invention comprises a first step wherein a metal powder, the size of the grains of which is comprised between 10 and 5000 nm, is deposited and then incorporated into the surface of the dielectric material. In a second step of the method, the dielectric material which is so impregnated with metal, is immersed into an autocatalytic bath to coat the impregnated zones of the material with a layer of the metal contained in the bath in a thickness which is proportional to the immersion time. This method enables to metallize materials such as oxides, polymers and composites containing these oxides and/or these polymers. The characteristics of the metal deposits are controlled, on the one hand, by the type of metal, and the size and the geometry of the metal powder grains and, on the other hand, by the type and the structure of the dielectric materials coated with these deposits.
