Abstract:
A mesoscale microelectromechanical system (MEMS) package for a micro-machine. The mesoscale micro-machine is formed on a printed circuit board (10) at the same time and of the same materials as the mesoscale micro-machine package. Both the micro-machine and the package have a first metal layer (12, 16), an insulating member (22, 26) formed on the first metal layer, and a second metal layer (32, 36) situated on the insulating layer. The package consists of a perimeter wall surrounding the micro-machine and a low-flow capping adhesive layer (40). The first metal layers of both the micro-machine and the package are formed in the same process sequence, and the insulating layers of both the micro-machine and the package are formed in the same process sequence, and the second metal layers of both the micro-machine and the package are formed in the same process sequence. The low-flow capping adhesive secures an optional cover (46) on the package to provide an environmental seal.
Abstract:
A meso-scale MEMS device having a movable member (51) is formed using standard printed wiring board and high density interconnect technologies and practices. In one embodiment, sacrificial material disposed about the movable member (51) is removed through openings (101, 102) as formed through a cover (91) to form a cavity (121) that retains and limits the freedom of movement of the movable member (51). The movable member can support a reflective surface (224) to thereby provide a mechanism that will support a projection display and/or image scanner (such as a bar code scanner).
Abstract:
An organic semiconductor device ( 11 ) can be embedded within a printed wiring board ( 10 ). In various embodiments, the embedded device ( 11 ) can be accompanied by other organic semiconductor devices ( 31 ) and/or passive electrical components ( 26 ). When so embedded, conductive vias ( 41, 42, 43 ) can be used to facilitate electrical connection to the embedded device. In various embodiments, specific categories of materials and/or processing steps are used to facilitate the making of organic semiconductors and/or passive electrical components, embedded or otherwise.

Abstract:
A meso-scale MEMS device having a cantilevered beam (113) is formed using standard printed wiring board and high density interconnect technologies and practices. The beam includes at least some polymer material (71) to constitute its length, and in some embodiments also comprises a conductive material as a load-bearing component thereof. In varying embodiments, the beam is attached at a location proximal to an end thereof, or distal to an end thereof.
