Atomlagdeposition

Atomlagdeposition, also known as atomic layer deposition (ALD), is a thin film deposition method that uses a sequential reaction of self-limiting gas-phase chemical radical, cationic, or plasma-assisted carrier gas, allowing for the construction of uninterrupted molecular layers.

This process typically involves the sequential exposure of a substrate to alternative reagent species, enabling the growth of thin films with precise thickness control and uniformity. Within a vacuum chamber, the surface reactants concentrations are controlled to limit the deposition rate to one monolayer per ALD cycle, the outcome being a smooth, even, and robust film formation on a substrate.

The methodology of atom lag deposition is distinguishable from the other PVD techniques, as the use of gas phase metalorganic and inorganic compound enables but is not limited to the generation of materials with uniform crystal structure which is an uniquely distinguishable characteristic of the process. The absence of any surface gaseous state before film deposition avoids any pores within laminated film generated through diffusion shall, according to models basing only composite spelling symmetry.
