    摘要: An inkjet printhead and a method of fabricating an inkjet printhead is disclosed. The inkjet printhead includes a conducting material layer deposited on an insulative dielectric. The conducting material layer has a chamber formed between a first and a second section of the conducting material layer. A dielectric material is fabricated on the first and second sections of the conducting material layer and on the insulative dielectric in the chamber. The dielectric material has a planarized top surface. A first via is formed in the dielectric material, thereby exposing a portion of the first section of the conducting material layer. A second via is formed in the dielectric material, thereby exposing a portion of the second section of the conducting material layer. The first and second vias each having sidewalls sloped at an angle in the range of approximately 10-60 degrees. A resistive material layer is formed in the first and second vias and on the planarization dielectric between the first and second vias through a single photoresist mask and a single etch process. A passivation material layer is formed onto the planarization dielectric material and onto the resistive material layer.
