Abstract:
An automated system capable of processing one or more substrates, comprising:an inkjet print head for spraying a microdroplet comprising a chemical species on a substrate; a scanning transport for scanning the substrate adjacent to the print head to selectively deposit the microdroplet at specified sites; a flow cell for treating the substrate on which the microdroplet is deposited by exposing the substrate to one or more selected fluids; a treating transport for moving the substrate between the print head and the flow cell for treatment in the flow cell, wherein said treating transport and said scanning transport are different elements; and an alignment unit for aligning the substrate correctly relative to the print head each time when the substrate is positioned adjacent to the print head for deposition.
