Research on micro component self-assembly is required to achieve fabrication of functional MEMS devices aggregated from different components of different materials. Self-assembly is a process in which components spontaneously form ordered aggregates without human intervention. In this paper, we propose DNA self-assembly in which micro components are assembled on designated locations on Si substrate, utilizing DNA base sequence complementation and hybridization for adhesion. Surface coverage of thiol modified single strand DNA on 20μm square Au binding sites on Si substrate are measured, so as to verify the number of single strand DNA involved in the hybridization bonding between component and substrate.
