Abstract: A selectively compliant chuck for assembling tiles into larger LCD displays facilitates alignment between a cover plate and a tile. A linear clutch is positioned between the tile chuck and the tile chuck carrier. This allows each chuck to float in the axis perpendicular to the tile's mating surface. The chuck has freedom to move linearly in this axis, and allows for pitch and roll motion as well. This floating connection can be turned on or off at will. Thus, a tile attached to the chuck can be lowered to intimately contact a cover plate and the chuck will compliantly move for high mating tolerances. Thereafter, the clutch can be locked to fix the chuck in it's current position. In this manner, the tile can be raised so that an adhesive can be applied to the cover plate. The tile can then be lowered back over the adhesive with the clutch locked and alignment maintained.

A first mask is disposed over electrically conductive material and semiconductive material and includes apertures that are alignable between rows of pixels of the field emission array. Row lines of the field emission array are defined through the first mask. A passivation layer is then disposed over at least selected portions of the field emission array.

The second mask is used in defining openings through the passivation layer and over the pixel regions of the field emission array. Conductive material exposed through the apertures of the second mask may also be removed to expose the underlying semiconductive grid and to further define the pixel openings.

Abstract: A field emission device is disclosed having a buffer layer positioned between an underlying cathode conductive layer and an overlying resistor layer. The buffer layer consists of substantially undoped amorphous silicon. Any pinhole defects or discontinuities that extend through the resistor layer terminate at the buffer layer, thereby preventing the problems otherwise caused by pinhole defects. In particular, the buffer layer prevents breakdown of the resistor layer, thereby reducing the possibility of short circuiting. The buffer layer further reduces the risk of delamination of various layers or other irregularities arising from subsequent processing steps. Also disclosed are methods of making and using the field emission device having the buffer layer.
