Abstract:
Methods of forming structures including a stress management layer for photolithography and structures including the stress management layer are disclosed. Further disclosed are systems for depositing a stress management layer. Exemplary methods include forming the stress management layer using one or more of plasma-enhanced cyclic (e.g., atomic layer) deposition and plasma-enhanced chemical vapor deposition.
