Abstract

A hybrid process combines a thin-film surface micromachining process such as by sputtering, evaporation or chemical vapor deposition with a thick-film surface micromachining and release process such as dry-film lamination. Such combination results in thin film micro-structures with all the benefits of surface micromachining without the typical problems of stiction and limited range of motion.
