TWO-AXIS SPIN COATING METHOD AND APPARATUS
20230124666 · 2023-04-20 ·

A modified technology of spin coating which is named Two-Axis spin coating is disclosed. The innovative Two-Axis spin coating apparatus is a rotary device that spins the substrate horizontally the same as conventional spin coaters while the whole horizontal spinning system can be rotated vertically. The vertical rotation of the substrate generates a vertical centrifugal force perpendicular to the surface of the substrate which allows the coating face with an elevated artificial gravity acceleration. The elevation of gravity acceleration adjusts and normalizes the local high and low surface tension stresses on the surface of the coated film. This elevation of gravity also increases the weight of coating elements artificially and obliges the wavy surface convex regions to flow toward the concave areas. The elevation of gravity also obliges the lighter probable air bubbles inside the layer, immediately before the coating surface skinning process, move toward the surface and drain out from the layer. The invention provides a method to level the layer's edge beads, level the coated surface, drain out probable micro sized air bubbles inside the layer and form denser film simultaneously.
