Reaction mechanism studies on atomic layer deposition process of AlF<sub>3</sub>

نویسندگان

چکیده

In this work, the reaction mechanism in atomic layer deposition (ALD) process of AlF3 thin films is studied with situ quartz crystal microbalance and quadrupole mass spectrometer. The depositions are done AlCl3 TiF4 as precursors. Similar to many metal fluoride deposited by ALD, growth rate strongly temperature dependent. addition, at low temperatures, exceptionally high for a traditional ALD process. study, reasons behind these characteristics detailed step-by-step film presented.

Reaction Path Analysis for Atomic Layer Deposition Processes

In this paper, we examine the mathematical structure of thin-film deposition process reaction kinetics models with the goal of determining whether a reaction network can guarantee the self-limiting and stable growth inherent in true atomic layer deposition systems. This analysis is based on identifying reaction invariants and interpreting the chemical significance of these conserved modes. A sp...
