A carrier for supporting a substrate during processing by a meniscus fowled by upper and lower proximity heads is described. The carrier includes a frame having an opening sized for receiving a substrate and a plurality of support pins for supporting the substrate within the opening. The opening is slightly larger than the substrate such that a gap exists between the substrate and the opening Means for reducing a size and frequency of entrance and/or exit marks on substrates is provided, the means aiding and encouraging liquid from the meniscus to evacuate the gap. A method for reducing the size and frequency of entrance and exit marks is also provided.
A method for forming a substrate carrier for use with a meniscus forming proximity head for substrate processing, comprising:
