Abstract
Embodiments of the device relate to a modular injector (100) for injecting a gas into a processing chamber (42), comprising at least two adjacent injectors (1), each injector comprising an inlet for receiving a gas wave or a gas flow, a flow shaping section (2) having left and right sidewalls that diverge according to a divergence angle relative to a propagation axis of the gas, for expanding the gas in a direction perpendicular to the propagation axis, and an outlet for expelling the gas. The modular injector forms an equivalent large injector having an equivalent large outlet which includes the outlets of the adjacent injectors and expands the gas over the equivalent large outlet.
