ABSTRACT:
A photoresist and etch method is used to manufacture valve elements of an ink jet printer. The method involves the building of successive layers upon a substrate, with the layers including conductive spacer layers which may be dissolved and plated layers that resist the dissolving. The resulting structure is a very small structure manufactured to extreme accuracy.
