Claim 0:
1. A fluid handling structure (structure) for a gas phase deposition apparatus, the structure defining a flow path with an inlet and an outlet for transmitting pressurized fluid from said inlet to the outlet,
wherein the structure includes:
an elongated slit, and
a series of nozzles through which pressurized fluid is allowed to enter the elongated slit,

wherein the inlet is upstream the series of nozzles,
wherein the outlet is formed downstream at a gap opening of the elongated slit allowing pressurized fluid to discharge from the elongated slit,
wherein the series of nozzles provide a larger flow resistance than the elongated slit,
wherein the series of nozzles form a series of jet flows directed towards one or more impingement surfaces of the structure as pressurized fluid is transmitted through the flow path,
wherein the elongate slit is defined between a first wall and a second wall spaced across a gap from the first wall, and
wherein the second wall includes a series of cavities arranged for receiving the formed jets as pressurized fluid is transmitted through the flow path, and wherein the impingement surfaces are formed by the series of cavities.
