Schematic of ALD chamber: a the precursors and N2 gas are pulsed in through the gas inlets and exit through the exhaust, making the gas flow from left to right over the silver knife. b The knife made two points of contact with the ALD chamber floor, one on the blade and the other at a high point on the handle. Side A is defined as side of the knife that faced the ALD chamber lid during the first half of deposition, Side B is defined as the stamped knife side that faced the chamber floor during the first half of deposition
