Abstract

The needs to establish ultra-precision mechanical fabrication processes to produce “micro-functional structures”, which have microstructures on their surfaces and/or inside, and capable of performing various functions, are inarguably growing stronger and stronger. In industries today, holographic optical elements (OHE), silicon-on-insulator (DOI) substrates and semiconductor devices wafers for ultra-large scale integrated circuits (ULSI), micro-lens and micro-parts / components are good examples of micro-functional structures in the field of optoelectronics and mechatronics. For all these application, the definition of precision engineering was change by a few orders of magnitude. Some example of new precision engineering processes will be presented. This will include atomistic level polishing of AlTiC magnetic heads, micro-spherical lens fabrication, and molecular dynamics (MD) simulation of the abrasive processes. Finally, some of the limitations of the precision engineering processes will be pointed out.
