Atomic Layer Deposition

Due to high controllability of deposition parameters (thickness; composition and structure), excellent uniformity and consistency, atomic layer deposition has gained broad applications micro/nanoelectronics and nanomaterials. Below is one of the major applications:

Magnetic read head

Thin films such as Al2O3 by atomic layer deposition have found application in magnetic read head in hard drives. Due to low cost, high quality and simple process, ALD thin films have quickly replaced sputtered films in this application area.
