A machine used for spin coating is called a spin coater, or simply spinner. [1] Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved. The applied solvent is usually volatile, and simultaneously evaporates. The higher the angular speed of spinning
A common issue in spin coating is a "beading" up of solvent at the edge of the silicon wafer. A process known as backside washing is most commonly used to spin this bead off of the wafer. By programming multiple different spin speeds into the spin coating apparatus the thickness of the solvent can be made uniform without the "beading" up at the ...
For example, a whole car has been coated with spray assembly, optically transparent films have been prepared with spin assembly, etc. [1] Characterization of LbL film deposition is typically done by optical techniques such as dual polarisation interferometry or ellipsometry or mechanical techniques such as quartz crystal microbalance.
Spin casting is a favored method for fabricating items in the specified materials – low temperature metals and thermoset plastics. Compared to the two main competing processes, injection molding and (zinc) die-casting, spin casting has significant advantages in terms of startup cost and ease of use.
Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
This is a list of television programs currently or formerly broadcast by Cartoon Network in the United States. The network was launched on October 1, 1992, and airs mainly animated programming, ranging from action to animated comedy.
The wagon-wheel effect is most often seen in film or television depictions of stagecoaches or wagons in Western movies, although recordings of any regularly spoked rotating object will show it, such as helicopter rotors, aircraft propellers and car rims. In these recorded media, the effect is a result of temporal aliasing. [1]
