Abstract:
1. A device comprising: a. a substrate having a top surface, a bottom surface, and a edge surface; b. a chip, having micro-mechanical components incorporated in a top surface, coupled to the top surface of the substrate; the top surface of the chip substantially parallel to the top surface of the substrate; c. a plastic mold member, having a substantially flat top surface, a substantially flat bottom surface, a substantially straight outer surface, and a substantially straight inner surface forming a hollow center portion, encapsulating a portion of the top surface and the entire edge surface of the substrate; the bottom surface of the plastic mold member and the bottom surface of the substrate being substantially co-planar; a notch near the intersection of the top surface and the inner surface of the plastic mold member adapted to receive a chemical substance suitable for releasing passivants to coat the mechanical components; d. the top surface of the plastic mold member adaptable to receive a cover lid member; and e. a gap of predetermined width between the micro-mechanical components in the top surface of the chip and the cover lid member free of solid material.
