A method of coupling an integrated circuit to a substrate includes providing the substrate, forming a contact pad in the substrate, contacting the contact pad with a solder ball, and repeatedly exposing the solder ball to a thermal process to cause intermetallics based on a metal in the contact pad to be formed in the thermal ball.

Creation of lead-free solder joint with intermetallics

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.

Optical micro plugs for multichannel and multilayer pharmaceutical device

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.

Method to produce pedestal features in constrained sintered substrates

A cost-effective surface metallization structure of a TCA carrier is produced by using a high-grit conducting paste to fill TSM vias in the TSM of the TCA carrier. This concept can be applied to alumina substrates with refractory metal conductors or to LCGC substrates with more noble metal conductors.

Surface metallization structure for multiple chip test and burn-in

A multilayer ceramic substrate electronic component is provided having high temperature superconductor material circuitry. The high temperature superconductor material is preferably yttrium-barium-copper-oxide and is encased within a noble metal such as silver or gold when forming the surface circuitry or filling of the vias. The noble metal layers preferably have through-openings to enable direct connection of circuitry to the encased superconductor layer. A method is also provided for fabricating such multilayer ceramic substrate electronic components.

Disclosed is a method of forming an aluminum nitride article. The method includes the steps of adding platinum to a composition including a binder, aluminum nitride particles and a sintering aid; forming the composition into an article; placing the article in a substantially non-carbonaceous container; and sintering the article in a reducing atmosphere to cause removal of the binder and densification of the aluminum nitride article, wherein the platinum catalyzes the removal of the binder.
