| 摘要 |
In one aspect, the invention includes a method of forming a layer of particulates on a substrate, comprising: a) fastening a first substrate to a second substrate; b) while the first substrate is fastened to the second substrate, submerging at least a portion of the first substrate in a liquid; c) suspending particulates on an upper surface of the liquid; d) moving the submerged first substrate relative to the suspended particulates to form a layer of the particulates supported on the first substrate; and e) removing the first substrate from the second substrate. In another aspect, the invention includes a layer forming apparatus, comprising: a) a vessel configured to retain a liquid; b) a pusher bar joined to the vessel and configured to compress particulates on an upper surface of the liquid; c) a conveyor which enters and exits the vessel, the conveyor being configured to removably retain substrates and to transport such substrates through the vessel, the conveyor having a front surface that faces the pusher bar and a back surface in opposing orientation relative to the front surface; and d) the vessel, conveyor and pusher bar being configured to form a layer of the particulates on substrates as the substrates are transported through the vessel by the conveyor.
