ABSTRACT:
A method of creating an electrical connection involves providing a pair of contacts each on one of two different chips, the pair of contacts defining a volume therebetween, the volume containing at least two compositions each having melting points, the compositions having been selected such that heating to a first temperature will cause a change in at least one of the at least two compositions such that the change will result in a new composition having a new composition melting point of a second temperature, greater than the first temperature and the melting point of at least a first of the at least two compositions, and heating the pair of contacts and the at least two compositions to the first temperature.
