Abstract
A method of manufacturing a printhead includes providing a polymeric substrate having a surface; providing a patterned material layer on the surface of the polymeric substrate; and removing at least some of the polymeric substrate not covered by the patterned material layer using an etching process.
Claims15
A method of manufacturing a printhead comprising:
- providing a polymeric substrate having a surface;
- providing a patterned material layer on the surface of the polymeric substrate by depositing the material layer directly on the surface of the polymeric substrate and then patterning the material layer;
- and
- removing at least some of the polymeric substrate not covered by the patterned material layer using an etching process.

A method of manufacturing a printhead comprising:
- providing a polymeric substrate having a first surface and a second surface;
- providing a patterned material layer on the first surface of the polymeric substrate;
- depositing a second patterned material layer on the second surface of the polymeric substrate;
- and
- removing at least some of the polymeric substrate not covered by the patterned material layer using an etching process.
