    摘要： The present invention relates generally to a new multi-density ceramic structure and process thereof. Basically, the present invention relates to a structure and method for forming laminated structures and more particularly to a structure and method for fabricating multi-layer ceramic products using very thin green sheets and/or green sheets with very dense electrically conductive patterns on top of thicker green sheet. The structure and method of the present invention enables the screening, stacking and handling of very thin green sheets and/or green sheets with very dense metallized patterns in the manufacture of multi-layer ceramic packages. The thin punched green sheets were tacked/bonded to thicker punched and screened green sheets to form a sub-structure which had excellent stability in screening and enabled further processing.

    摘要： The present invention relates generally to a new apparatus and method for forming cavities in semiconductor substrates using at least one flexible preform insert. More particularly, the invention encompasses apparatus and method for fabricating cavities in MLC (multi-layer ceramic) substrates using at least one flexible preform insert that is inserted into the cavity of the MLC substrate prior to lamination and this insert helps in preventing the collapse of the shelves of the cavity during this lamination process. After the lamination process the inventive temporary preform insert is then removed.

    摘要： Methods of making and the resultant micro-spotting plates having a plurality of feed holes, a plurality of dispensing nozzles, an open cavity in communication with the dispensing nozzles and a plurality of channels. The channels connect the feed holes to the dispensing nozzles for transferring a fluid from the feed holes to the dispensing nozzles under a capillary force. A channel may connect a single feed hole retaining a liquid to a dispensing nozzle for dispensing such liquid, or a channel may connect two or more feed holes to a dispensing nozzle for enabling mixing of fluids from the feed holes within the channel prior to dispensing such mixture. The micro-spotting plates allow the continuous self-feeding flow of fluids by capillary forces through its hydrophilic layers for enabling the controlled dispensing of a multi-array of drops of fluids onto a substrate, preferably a test slide, for later use.
