Atomic Layer Deposition

Atomic layer deposition (ALD) is a thin film deposition technique that is based on the sequential use of a gas phase chemical process. The majority of ALD reactions use two chemicals, typically called precursors. These precursors react with a surface one at a time in a sequential, self-limiting, manner. By exposing the precursors to the growth surface repeatedly, a thin film is deposited.

Famous quotes containing the words atomic and/or layer:

    Quite often ... these little guys, who might be making atomic weapons or who might be guilty of some human rights violation ... are looking for someone to listen to their problems and help them communicate.
    Jimmy Carter (James Earl Carter, Jr.)

    After a few months’ acquaintance with European “coffee,” one’s mind weakens, and his faith with it, and he begins to wonder if the rich beverage of home, with its clotted layer of yellow cream on top of it, is not a mere dream after all, and a thing which never existed.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
