Abstract
A method of fabricating inkjet print heads usable in an ink jet printer. The method of fabricating ink jet print heads includes preparing a plurality of ink jet print heads on a wafer while forming sub sidewalls around the ink jet print heads when the ink jet print heads are being prepared, attaching protection films onto the sub sidewalls of the wafer and the ink jet print heads, and dicing the ink jet print heads and detaching the individual ink jet print heads from the wafer. In the method, the ink jet print heads are diced in a wafer unit. Particularly, connect pads of the ink jet print heads can be prevented from being contaminated by the protection films.
