Publication number: 20090186293Abstract: A method for making a dry film photoresist layer for a micro-fluid ejection head and a micro-fluid ejection head made by the method. The method includes applying a photoimageable liquid to a moving web of release material to provide a photoimageable layer on the release material using a slot die coater. The layer on the release material has a coating thickness ranging from about 8 to about 25 microns with a thickness variation of no more than about one micron. The photoimageable layer on the web is dried to provide a dry film photoresist layer. A protective web is then applied to the dry film photoresist layer.Type: ApplicationFiled: January 23, 2008Publication date: July 23, 2009Inventors: Bryan Thomas Fannin, David Christopher Graham, Sean Terrance Weaver
