Abstract
An ink-jet printhead, and a method for manufacturing the same. The printhead includes a substrate, a first insulating layer on the surface of the substrate, first and second conductors on the first insulating layer separated from each other, a heater including conductor connection layers for electrically connecting the first and second conductors to each other and between the first and second conductors. A second insulating layer is between the first and second conductors and between the conductor connection layers, and a barrier wall is provided on the substrate and defines an ink chamber filled with ink to be ejected. A nozzle plate is provided on the barrier wall, and forms upper walls of the ink chamber and in which nozzles, through which ink filled in the ink chamber is ejected, are formed.
Claims11
An ink-jet printhead comprising:
- a substrate;
- a first insulating layer on the surface of the substrate;
- first and second conductors on the first insulating layer separated from each other;
- a heater including a plurality of conductor connection layers electrically connecting the first and second conductors to each other, and between the first and second conductors;
- a second insulating layer between the first and second conductors and between the plurality of conductor connection layers;
- a barrier wall on the substrate and defining an ink chamber with ink to be ejected;
- and
- a nozzle plate on the barrier wall, forming upper walls of the ink chamber and in which nozzles through which ink filled in the ink chamber is ejected are formed.
An ink-jet printhead, comprising:
- a substrate;
- a plurality of conductors positioned on the substrate;
- and
- a plurality of connection layers connecting at least one of the conductors to another conductor,
- wherein the connected conductors form a heater such that an additional resistance material need not be provided.
