Atomic Layer Deposition (ALD) Processes for ULSI Manufacturing

  • Schubert S. ChuEmail author


Atomic layer deposition (ALD) is a technique where precursors are introduced alternatively, and a monolayer (or fraction thereof) is deposited on the surface at a time [1–4]. The sequential introduction of all precursors, separated by purge steps, completes an ALD cycle. Figure 14.1 illustrates the steps that comprise an ALD cycle.
