发明名称 Edge feed ink delivery thermal inkjet printhead structure and method of fabrication
摘要 This invention provides an apparatus and method of fabrication thereof for an inkjet printhead with an improved ink flow path between an ink reservoir and vaporization chambers in an inkjet printhead. In the preferred embodiment, a barrier layer containing ink channels and vaporization chambers is located between a rectangular substrate and a nozzle member containing an array of orifices. The substrate contains two linear arrays of heater elements, and each orifice in the nozzle member is associated with a vaporization chamber and heater element. The ink channels in the barrier layer have ink entrances generally running along two opposite edges of the substrate so that ink flowing around the edges of the substrate gain access to the ink channels and to the vaporization chambers. The apparatus is fabricated without using ion implant technology.
