# Layer (electronics)

A layer is the deposition of molecules on a substrate or base (glass, ceramic, semiconductor, or plastic/bioplastic).

High temperature substrates includes stainless steel and polyimide film (expensive) and PET (cheap).

A depth of less than one micrometre is generally called a thin film while a depth greater than one micrometre is called a coating.

A web is a flexible substrate.
