Abstract
Methods and structures relating to the formation of mixed SAMs for preventing undesirable growth or nucleation on exposed surfaces inside a reactor are described. A mixed SAM can be formed on surfaces for which nucleation is not desired by introducing a first SAM precursor having molecules of a first length and a second SAM precursor having molecules of a second length shorter than the first. Examples of exposed surfaces for which a mixed SAM can be provided over include reactor surfaces and select surfaces of integrated circuit structures, such as insulator and dielectric layers.
