NOVELTY - The installation (1) has a transfer area (14) including a particle inlet (22) and a particle outlet (26) spaced apart from each other by two opposite side rims (28), and retaining carrier liquid (16) i.e. water, on which particles float. A capillary bridge (42) provides a connection between the carrier liquid contained in the transfer area and a substrate (38). Suction nozzles (32a, 32b) enable to draw the particles present in the transfer area toward the side rims. A Teflon (RTM: PTFE) layer (50) enables temporary retention of the particles in the transfer area.    USE - Installation for depositing a film of ordered particles e.g. monolayer type silica particles, on a moving substrate. Uses include but are not limited to fuel cell application, optic al application, photonics application and polymer coating application, chips, microelectromechanical systems, and surface structural application for organic electronic and photovoltaic devices.    ADVANTAGE - The suction nozzles enable to draw the particles present in the transfer area toward the side rims so as to avoid formation of clusters and formation of vacuum particles, thus ensuring satisfactory ordering of the particles in the transfer area during activation phase. The nozzles are inactivated, so that automatic ordering of the particles is realized. The nozzles prevent evacuation of a part of the particles or the substrate during activation phase and prevent isolation of the portion of an end product issued from the activation phase, thus reducing manufacturing cost.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for depositing a film of ordered particles on a moving substrate.
