Abstract: The present disclosure relates to a method of forming a pattern on a semiconductor substrate. One or more layers are formed over the semiconductor substrate. A first self-assembled monolayer (SAM) layer is formed over the one or more layers, wherein the first SAM layer exhibits a first SAM pattern. At least a first of the one or more layers is patterned using the first SAM layer as a first etch mask to form first pillars in the first of the one or more layers and then removing the first SAM layer. A second self-assembled monolayer (SAM) layer is formed along sidewall portions of the first pillars after the first SAM layer has been removed, wherein the second SAM layer exhibits a second SAM pattern that differs from the first SAM pattern and where the second SAM layer differs in material composition from the first SAM layer.
