Methods and systems for forming a layer from a fluid mixture on a web are provided. The system includes a fluid delivery apparatus for delivering the fluid mixture onto the web. The fluid delivery apparatus includes a cascade device and a chemical dispenser device. The system also includes a fluid stirring apparatus comprising at least one fan positioned over the web and configured to generate a flow pattern that stirs the fluid mixture on the web while the layer is being formed, without the at least one fan contacting the fluid mixture. The system further includes a fluid removal apparatus having a rinsing device and a suction device. The rinsing device is configured to dispense a rinsing fluid onto the web. The suction device is configured to remove by suction the rinsing fluid and a remaining portion of the fluid mixture remaining on the web after formation of the layer.

A chemical bath deposition (CBD) apparatus includes a first cap, a second cap, and a solution input/output device. The second cap is arranged corresponding to the first cap so as to form a deposition space. The solution input/output device is located in the first cap so as to feed a solution into/out of the deposition space. The position of the solution input/output device is fixed, or the solution input/output device is movable in the deposition space.
摘要:
A coating apparatus includes modular interfaces and substrate receptors for accommodating various shapes and sizes of monolith substrates when coating layers are applied onto the monolith substrates. The monolith substrates are laterally surrounded by an elastically deformable sleeve that prevents lateral leakage of a vacuum out of the monolith substrate when a vacuum is applied to opposing ends of the monolith substrate, thereby eliminating needs for bulky vacuum chambers. The coating apparatus also includes valves and control apparatus that enable excess precursor liquid to be drained from monolith channels in-situ, without the use of additional spin-drying steps. Coating methods for using the coating apparatus are provided.
摘要:
A deposition process for coating a substrate with films of varying thickness on a substrate can be achieved. The thickness of the film deposition can be controlled by the separation between the substrate and a curtain. Different separation distances between the substrate and curtain in the same chemical bath will result in different film thicknesses depositing on the substrate.
摘要:
A deposition process for coating a substrate with films of a different thickness on front and rear surface of a substrate can be achieve in one growth. The thickness of the film deposition can be controlled by the separation between the substrates. Different separation distances between the substrates in the same chemical bath will result in different film thicknesses on the substrate. Substrates may be arranged to have different separation distances between front and back surfaces, a V-shaped arrangement, or placed next to a curtain with varying separation distances between a substrate and the curtain.
