ALD precursors

ALD (Atomic Layer Deposition) is a vapor-phase thin-film deposition method. It works by alternately introducing precursor A and co-reactant B in sequence, where each step proceeds via a surface self-limiting (self-saturating) reaction. As a result, the film grows in cycles, enabling ...

The primary distinction between Atomic Layer Deposition (ALD) and Chemical Vapor Deposition (CVD) is rooted in their deposition techniques, ability to regulate film characteristics, and appropriate applications. ALD is characterized by a step-by-step, self-terminating process that builds thin ...

Chemical vapor deposition (CVD) is a technique that employs gaseous or vaporized materials to react within the gas phase or at the gas-solid boundary, resulting in the formation of solid coatings. Atomic layer deposition (ALD), a specialized form of CVD, enables precise deposition at the atomic ...
