Further information

The spin coating chuck has a recess designed to hold the substrate securely in place by friction and centrifugal force, while allowing excess solution to escape.

This eliminates the need for a vacuum and significantly reduces substrate warpage for better film quality as shown in the figure below.


Vacuum warping of spin coater substrate
The effect of vacuum warpage during spin coating is shown in the left hand image of a thin film of fluorescent OLED material of approximately 70 nm thickness. By eliminating the vacuum during the spin coating process a much more uniform film can be obtained (right).

This two-level chuck offers full flexibility across our substrate ranges. The additional corner recesses on both levels also ensure excess solution can still escape. Further more it is ideal for use with our carrier plates allowing you to adapt the chuck to work with custom or alternative substrate sizes.
