Abstract: A method of making and the resultant micro well plate that includes a plurality of greensheets, either laminated or sintered together, whereby these greensheets have a plurality of vertical micro well reaction chamber openings therein, and optionally a plurality horizontal channels connecting selected well reaction chamber openings. The vertical micro well reaction chambers have at, at least one end thereof a plurality of optical micro plugs which are aligned to the vertical micro well reaction chamber openings. The plurality of optical micro plugs allow for the micro well plate to be integrated with macro analytical instrumentation for the analysis, examination, and/or testing of chemicals, reagents or samples provided within the vertical micro well reaction chamber openings.

Abstract: Methods to create raised pedestal parts in ceramic substrates sintered under a load. The invention uses a patterned, buried, non-sintering layer that provides the needed transfer of load during the sintering process to the raised or pedestal portion of the substrate while maintaining dimensional control of the metallized features on the surface of the pedestal base. The methods involve cutting channels in the ceramic substrate corresponding in position to the perimeter of the opening in the patterned non-sintering contact sheet. The channels may be cut either before or after the sintering of the ceramic substrates.

Abstract: A method and structure for filling an opening in a substrate which includes positioning a sheet above the substrate and punching the sheet into the opening in the substrate, wherein the sheet and the substrate have similar shrinkage characteristics when subjected to a subsequent sintering process.

Abstract: Disclosed is a multilayer ceramic substrate having an outer pad, for example an I/O pad, which is anchored to a middle pad of the multilayer ceramic substrate by a plurality of vias which in turn is anchored to an inner pad of the multilayer ceramic substrate by a second plurality of vias. The middle and outer pads and vias are made of high metal material, preferably 100% metal, so they won't adhere very well to the ceramic substrate. The inner pad is a composite metal/ceramic material which will bond very well to the ceramic substrate.

Abstract: Disclosed is a multilayer ceramic substrate having an outer pad, for example an I/O pad, which is anchored to an inner pad of the multilayer ceramic substrate by either a plurality of vias or one large via. The outer pad and vias are made of high metal material, preferably 100% metal, so they won't adhere very well to the ceramic substrate. The inner pad is a composite metal/ceramic material which will bond very well to the ceramic substrate.
