DIPPING

• it is the simplest method of deposition

• How is it done: a substrate is immersed in a solution containing the coating material and withdrawn

• Disadvantages:
  • Bad uniformity (it can be seen in the animation how the thickness varies due to gravitation force)
  • the layers may have poor quality, pinholes; the dipping is repeated in this case

• Film thickness: is dependent on the viscosity of the paint

• Applications:
  • for metals with low melting point
  • biosensors
