Abstract
In a process for sintering a metal member bonded to a substrate during which the metal member undergoes densification at a temperature which is different from the curing temperature of the substrate, an improvement is provided which comprises causing the densification temperature of the metal member to be closer to or identical with the curing temperature of the substrate by adding to said metal member prior to sintering an amount of organometallic compound which undergoes decomposition before the densification temperature of the metal member has been reached to provide under the sintering conditions employed a densification temperature-modifying amount of a metal or metal oxide which can be the same as or different from the metal of the aforesaid metal member. The improved sintering process of the present invention is particularly adapted for use in the fabrication of multilayer ceramic substrates which serve as circuit modules for seminconductor chips.
