  • Publication number: 20060210703
    Abstract: Provided are technologies for manufacturing protrusions having various properties better than the conventional technologies. The protrusions are manufactured by the steps comprising: filling a specific composition into slits by means of a squeegee printing method; curing the photosensitive resin in the composition by light exposure to make a cured composition from the composition; and firing the cured composition. These protrusions preferably have a relative dielectric constant of less than 4.0 and a difference in linear expansion coefficient of not more than 4 ppm/° C., based on the linear expansion coefficient of a dielectric layer material for use.
