    Abstract: The organic MEMS according to the present invention comprises a polymeric substrate comprising a substrate surface including a first region and a second region. A polymer coating is applied to the first region to provide a coating surface that is spaced apart from the substrate surface. A terminal is disposed on the second region. A metallic trace is affixed to the coating surface such that the metallic trace forms a flexible extension over the second region. The extension has a rest position where the extension is spaced apart from the terminal, and a flexed position where the extension is disposed towards the terminal. An actuator is used to provide an electric field to deflect the extension from the rest position to the flexed position. By changing the spacing between the extension and the terminal, it is possible to change the electrical condition provided by the MEMS.

    Abstract: A wafer (10) having integrated circuit elements formed therein is thinned and a first carrier (41) is adhered thereto. The first carrier (41) facilitates handling of the thinned wafer (30). A second carrier (51) is then adhered as well and the various integrated circuits are singulated to yield a plurality of thinned die (81). Once the thinned die is mounted to a desired substrate (91), the first carrier (41) is readily removed. In one embodiment, the first carrier (41) has an adhesive that becomes less adherent when exposed to a predetermined stimulus (such as a given temperature range or a given frequency range of photonic energy). Such thinned die (or modules containing such die) are readily amenable to stacking in order to achieve significantly increased circuit densities.

    Abstract: The invention provides a method for attaching a flip chip to a printed wiring board. A bumped opto-electronic or electromechanical flip chip is provided. An underfill material is applied to a first portion of the flip chip, wherein a second portion of the flip chip is free of the underfill material. The flip chip is positioned on a printed wiring board, and a bumped portion of the flip chip is heated to electrically connect the flip chip to the printed wiring board. The second portion of the flip chip remains free of the underfill material when the flip chip is electrically connected to the printed wiring board.

    Abstract: A field emitting device having a plurality of preformed emitter objects. The emitter objects include sharp geometric discontinuities, and a significant number of these geometric discontinuities are oriented in a way that supports desired field emission activity. Field emission devices built with such emitters can be utilized to provide a flat display screen.
