Abstract:
The present invention relates generally to a new interconnection and a method for making the same, and more particularly, to an elongated solder interconnection and a method for making the same. On an electronic carrier (12) a pad (14) is formed on which a solder mass (16) is deposited and capped with a metal layer (19), thereby forming an elongated solder interconnection. A further elongated solder interconnection can now be formed by forming a second solder mass (26) on the first solder mass that has been capped by a metal layer. Additional elongated solder interconnection can be formed by capping the preceding solder mass and/or the last solder mass with a metal capping layer. Alternatively, the encapsulating layer can be in the form of a sidewall spacer formed on the sidewalls of the solder mass.
