Micro electro-mechanical system with one or more moving parts method and apparatus

This invention relates generally to micro electro-mechanical system (MEMS) methods and apparatus. A meso-scale MEMS device having a movable member () is formed using standard printed wiring board and high density interconnect technologies and practices. In one embodiment, sacrificial material disposed about the movable member () is removed through openings () as formed through a cover () to form a cavity () that retains and limits the freedom of movement of the movable member (). The movable member can support a reflective surface () to thereby provide a mechanism that will support a projection display and/or image scanner (such as a bar code scanner).
