Abstract: The present invention relates generally to a new method and apparatus to enable high yielding double sided and/or multipass screening in the manufacture of multilayer ceramic packages.

Abstract: A method to control the post sinter distortion of free sintered multilayer ceramic substrates by placing a discrete non-densifying structure in the green ceramic laminate prior to sintering. One or several discrete non-densifying structures are placed on one or more ceramic greensheets which are then stacked and laminated to form a green ceramic laminate. The laminate is then sintered and the discrete non-densifying structure will locally control the dimensions of the free sintered multilayer ceramic substrate. The method can be used to control post sinter dimensions in MLC substrates manufactured as either single or multi-up substrates by placing the discrete non-densifying structure in the active area or in the kerf area between the individual product ups prior to sintering.

More particularly, the invention encompasses an apparatus and a method for fabricating cavities in semiconductor substrates wherein a coated membrane sheet is placed over the cavity prior to lamination and caused to conform to the contour of the cavity, thus preventing collapse of, or damage to, the cavity shelves during the lamination process. After the lamination process, the coated membrane is conveniently removed without causing damage to the cavity shelves or paste pull-outs.

Abstract: The surface metallurgy of a green sheet may be controlled during processing to provide an increased resistance to low strength structural failure of the metal-ceramic interface under an input-output pad structure and increased pin-pull strength of input-output pads on alumina multilayer ceramic substrates. The surface area on a green sheet in the region where an input-output pad is to be screened is roughened in order to increase the contact surface area between the green sheet and the input-output pad. The mechanical interlock between the metal-ceramic interface is strengthened by the increased number of bonding points between the green sheet and the input-output metallurgy and the use of different screening materials.
