Sub-Lithographic Patterning Via Tilted Ion Implantation For Scaling Beyond The 7nm Technology Node


Tilted ion implantation (TII) can be used in conjunction with pre-existing masking features on the surface of a substrate to form features with smaller dimensions and smaller pitch. In this paper, the resolution limit of this sub-lithographic patterning approach is examined via experiments as well as Monte Carlo process simulations. TII is shown to be capable of defining features with size belo... » read more
