Challenges for Non-Ideal Atomic Layer Deposition Processes & Systems

May 09, 2016 |

ALD has been described as a thin film deposition technology that can keep the semiconductor industry on track per Moore's law (or observation) [1] for a few more years. In its most ideal form, it is a process that enables monolayer, or sub-monolayer growth of certain materials through the sequential exposure of a functionalized substrate to a pair of precursor gases. If dosed correctly the gases attach at specific surface sites and react to create a near perfect film on the order of a few angstroms thick. Presently the U.S. Department of Defense anticipates that the last process node for semiconductor devices (the end of Moore's) is 7 nm and will be achieved by 2020 [2].
