摘要：
A structure and manufacturing process for electrothermal heaters for integrated printing heads where the axes of the ink nozzles are substantially normal to the plane of the heaters, and pass substantially through the centers of the heaters. The completed heater forms a loop, with the centre of the loop being formed by the nozzle etching process. A disk of heater material is formed on the substrate. The radius of the disk is equal to the radius of hole to be etched for the nozzle, plus the required heater width. The nozzle hole is subsequently etched from the centre of the heater disk. The remaining heater material is in the form of an annulus, with the internal radius being equal to the nozzle hole radius. The structure is subsequently coated with a layer of passivation material.

一种用于集成印刷头的电热加热器的结构和制造方法，其中喷嘴的轴线基本上垂直于加热器的平面，并且基本上通过加热器的中心。 完成的加热器形成环，其中心通过喷嘴蚀刻工艺形成。 在基板上形成加热材料盘。 圆盘的半径等于要喷嘴的待蚀刻孔的半径，加上所需的加热器宽度。 随后从加热盘的中心蚀刻喷嘴孔。 剩余的加热器材料是环形的，其内半径等于喷嘴孔半径。 随后用一层钝化材料涂覆该结构。
