    摘要： A fluid ejection device (1), comprising: a first semiconductor body (2) including an actuator (3), which is operatively coupled to a chamber (6) for containing the fluid and is configured to cause ejection of the fluid; and a channel (11a) for inlet of the fluid, which extends in a first direction (Z) and has a section having a first dimension (A 1 ); and a second semiconductor body (8), which is coupled to the first semiconductor body (2) and has an ejection nozzle (13) configured to expel the fluid. The second semiconductor body (8) further comprises a first restriction channel (16), which is fluidically coupled to the inlet channel (11a), extends in a second direction (X) orthogonal to the first direction (Z) and has a respective section with a second dimension (A 3 ) smaller than the first dimension (A 1 ) so as to form a restriction between the inlet channel (11a) and the chamber (6).
