Computational fluid dynamics modeling of spatial atomic layer deposition on microgroove substrates

•The effect of microgroove structure on the fluid dynamics and film conformality in spatial atomic layer deposition is investigated.•Microgroove structure hinders the precursor inflow and purging gas outflow, leading to non-uniformity of precursor distribution.•Both growth per cycle and film conform...
