Industry needs increasingly smaller devices for electrical systems. In particular, smaller circuit boards will facilitate more efficient nanoscale devices for micro-electromechanical systems (MEMS). The technique of microcontact printing (mCP), an inexpensive alternative to photolithography, can be achieved using self-assembled monolayers (SAMs) derived from aliphatic dithiocarboxylic acids (ADTCAs). The process enhances the integrity of circuits and can be achieved without the deterioration of pre-etched structures. Work during the past year involved the preparation of PDMS stamps for patterning metal surfaces with self-assembled monolayers. The work has advantages in industrial applications because of the quickness of the patterning, the reproducible quality of the pattern, and the robustness of stamps. Ongoing efforts seek to print the SAMs on the surface of gold by inking stamps with a solution of thiols and pressing them by hand against a surface of gold.
