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.
Claims2
A method of manufacturing a printhead comprising:
- providing a polymeric substrate on a carrier substrate with a first material layer positioned between the polymeric substrate and the carrier substrate, the first material layer including a drop forming mechanism, the first material layer being laminated to the carrier substrate with a laminate;
- providing a patterned second material layer on a surface of the polymeric substrate that does not contact the first material layer;
- removing at least some of the polymeric substrate not covered by the patterned second material layer using an etching process;
- removing the first material layer, the polymeric substrate, and the second material layer from the carrier substrate by delaminating the first material layer, the polymeric substrate, and the second material layer from the carrier substrate;
- and
- patterning the first material layer.
