Abstract:
A fluid ejection device, comprising: a first semiconductor body including an actuator, which is operatively coupled to a chamber for containing the fluid and is configured to cause ejection of the fluid; and a channel for inlet of the fluid, which extends in a first direction and has a section having a first dimension; and a second semiconductor body, which is coupled to the first semiconductor body and has an ejection nozzle configured to expel the fluid. The second semiconductor body further comprises a first restriction channel, which is fluidically coupled to the inlet channel, extends in a second direction orthogonal to the first direction and has a respective section with a second dimension smaller than the first dimension so as to form a restriction between the inlet channel and the chamber.
