Mikko Utriainen VTT Finalnd explains PillarHall ALD test structures

PillarHall® silicon wafers and chips enable easy analysis of thin film conformality using well-defined, record-demanding microscopic 3-D structures. Typical usage areas are atomic layer deposition and chemical vapor deposition R&D.
