According to an embodiment of the present invention, an improved method
and system are provided. In one embodiment, a conductive connection is
made between two metal layers separated by an intermediate insulating
layer by providing vias between one of the metal layers and the
insulating layer. A conductor, such as a conductive sphere made of gold
is disposed into the vias and pressed so as to create a conductive
connection between the metal layers. In a further embodiment, vias are
created in both metal layers. In such a case, a fixture support may be
provided so that when the conductive sphere is pressed into the vias, it
is also pressed into the support to improve the conductive connection.
