Question

_____________ involves depositing successive layers of different substances to produce layered, crystalline films.

(a) Atomic layer chemical vapor deposition

(b) Combustion chemical vapor deposition

(c) Low pressure chemical vapor deposition

(d) Plasma enhanced chemical vapor deposition

The question was posed to me at a job interview.

I need to ask this question from Blending and Vapor Deposition in Thermoplastics in chapter Thermoplastic Polymers Properties & Processing of Food Packaging Technology

Answer 1

Right option is (a) Atomic layer chemical vapor deposition

To elaborate: Atomic layer chemical vapor deposition (ALCVD) involves depositing successive layers of different substances to produce layered, crystalline films. In short, ALCVD is a method in chemical vapor deposition in which deposition occurs through chemisorption of pulsed chemical reactant.
