Abstract
A method of manufacturing a fluid injection device. The method of the present invention applies a compensated geometric shape of the unetched isolating portions to increase the additional compensated portion for etching, or the ion implanting process to reduce the etching rate of the unetched isolating portions. Thus, crosstalk or overshoot in the isolating portions of the fluid injection device can be reduced, and the fluid injection device can be precisely manufactured in a small size.
