Abstract:
A back-shooting inkjet print head comprising:a first substrate that has a front surface and a back surface, wherein the back surface comprises a thermal barrier layer, a plurality of resistors within a thermal resistor layer and a conductive layer formed thereon, while a plurality of orifices are formed through the first substrate, the thermal barrier layer, the thermal resistor layer and the conductive layer, respectively proximate to each of the resistors; an isolation layer that has a plurality of ink channels formed therethrough, wherein the isolation layer is arranged on the back surface of the first substrate such that the region of each ink channel covers the region of one of the resistors and one of the orifices therein; and a second substrate that has an ink supply window formed therethrough, wherein the second substrate is arranged on the isolation layer such that the ink supply window, communicating with the ink channels, is located at one side of the resistors, while the orifices of the first substrate are located at the other side of the resistors facing the second substrate.
