Abstract
A metal paste comprising ultrafine particles of a metal. The particles have a particle size of 1000 angstroms (0.1 micron) or less and are individually uniformly dispersed in an organic solvent. A process for producing a metal paste comprises the steps of evaporating a metal in a vacuum chamber in an atmosphere of an inert gas at a pressure of 10 Torr or less and of collecting the vapor of the evaporated metal on a cooling surface in the form of ultrafine particles having a particle size of 1000 angstroms (0.1 micron) or less, wherein a vapor of an organic solvent is introduced into the vacuum chamber while the metal is being evaporated. A method for preparing a metallic thin film having a thickness of between 0.01 micron and 1 micron uses a metal paste containing ultrafine metal particles having a diameter of 0.1 micron or less uniformly dispersed in an organic solvent. In the method, the metal paste is coated on a substrate, dried and sintered.
