A method for forming a film pattern includes applying a water-soluble photosensitive resin on a substrate, exposing the photosensitive resin to light, developing the photosensitive resin with a developer, after developing the photosensitive resin, depositing a material for the film pattern on the substrate, and, after depositing the material for the film pattern, removing photosensitive resin remaining on the substrate with a remover. The remover and the developer include the same solute, and a concentration of the solute in the remover is higher than that in the developer.

Method for forming film pattern

The present invention is to provide a method for forming various patterns such as a metal or metal compound pattern, in which the amounts of the materials constituting the pattern which are removed during the formation step can be suppressed to the minimum. The method comprises a resin pattern forming step of forming on the surface of a substrate a resin pattern capable of absorbing a solution containing metal components, an absorbing step of dipping the resin pattern in the solution containing metal components to make the resin pattern absorb the solution containing metal components, a washing step of washing the substrate having formed thereon the resin pattern that has absorbed the solution containing metal components, and a burning step of burning the resin pattern after washing.

Metal or metal compound pattern and forming method of pattern, and electron emitting device, electron source, and image-forming apparatus using the pattern

Provided is a method for producing a pattern of an electroconductive member, comprising: a step of forming a resin film on a substrate surface; a step of incorporating the first metal component into the resin by applying to the resin a liquid which contains a complex of a first metal component, which contains also a second metal component different from the first component, and to which a compound forming a complex with the second metal component is contacting or contacted preliminary; and a step of baking the resin film to form the electroconductive member from the first metal component incorporated into the resin film. Thus, the second metal component is prevented from adversely affecting the first metal component to be incorporated into the resin.

Method of manufacturing electroconductive member pattern, and methods of manufacturing electron source and image displaying apparatus each using the same

A method for producing a pattern of an electroconductive member, comprises: a step of forming on a substrate surface a resin film containing acid group; a step of incorporating into the resin film a liquid containing a metal complex salt and having a pH value of 5 to 7; and a step of baking the resin film to form the electroconductive member from a metal component incorporated into the resin film, thereby improving uniformity and speed of an adsorbing of the metal component into the resin, and providing uniform characteristics of the electroconductive pattern.
