Abstract:
1. An apparatus for fabricating a functional device mounting board, comprising: a holder for holding a substrate on which a functional device is to be formed; a jet head for ejecting a droplet containing a functional material onto the substrate so as to form the functional device in a functional device forming area of the substrate, by allowing a volatile ingredient of the droplet to vaporize, while allowing a solid component to remain on the substrate; a data input unit for supplying droplet ejection information to the jet head, the jet head ejecting the droplet onto the substrate based on the droplet ejection information so as to form the functional device in the functional device forming area; a reservoir positioned under the substrate, the reservoir containing a solution of the functional material; a flexible tube connecting the reservoir to the jet head; and at least two types of filters positioned downstream of the reservoir, wherein a most downstream filter is fixed so as not to be detached.
