Abstract
A method of fabricating an ink jet recording head includes forming a photosensitive resin layer on a substrate having formed thereon an energy generation device for generating energy for ejecting recording droplets; pattern-wise exposing the photosensitive resin layer to an active radiation to a portion of the photosensitive resin layer where formation of a pattern of an ink fluid path is desired; laminating a top plate on the photosensitive resin layer; and eluting the pattern exposed portion of the photosensitive resin layer to form a pattern of an ink fluid path. An ink jet recording head includes a substrate a substrate; an energy generation device provided on the substrate and for generating energy for ejecting recording droplets; an exposed photosensitive resin layer provided on the substrate, the resin layer comprising a heat-crosslinking positive type resist material, and being provided with an ink fluid path defined between the substrate and the exposed photosensitive resin layer; a top plate laminated on the exposed photosensitive layer, the top plate being provided with an ink supply port communicating with the ink fluid path; and the ink fluid path ending as an ink ejection port on a side opposite to a side of the ink supply port. An ink jet recording apparatus includes a portion for mounting such an ink jet recording head.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
