Patent ID: 7553375

Claim:
A functional device mounting board fabricating system comprising: a fabrication apparatus; and a booth in which the fabrication apparatus is placed and a clean air supplying unit which supplies clean air around a substrate, wherein the fabrication apparatus comprises, a holder configured to support the substrate on which a functional device is to be formed, the substrate and the holder are configured to remain stationary with respect to the functional device mounting board fabrication system while a droplet containing a functional material is ejected onto the substrate; a jet head configured to eject the droplet onto the substrate so as to form the functional device, which functions under the application of voltage, in a functional device forming area of the substrate, by allowing a volatile ingredient of the droplet on the substrate to vaporize by heating process, while allowing a solid component to remain on the substrate; and a data input unit configured to supply 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, wherein the droplet ejection speed of the jet head is faster than the relative moving speed between the jet head and the substrate and faster than a clean air flow speed supplied by the clean air supplying unit by 2 m/s or more.
