Claim 19:
20. An integrated circuit package, comprising:
a first integrated circuit package module, including:
a first integrated circuit package device including a first contact element; and
a first bonding system formed on the first integrated circuit package device, the first bonding system including:
a first bonding system substrate; and
a first bonding element formed in the first bonding system substrate, the first bonding element comprising:
a first conduction component conductively connected to the first contact element, the first conduction component formed from a first metal having a first melting point; and
a first bonding component formed from a second metal, the second metal having a melting point lower than the first melting point; and

a second integrated circuit package module, including:
a second integrated circuit package device including a second contact element; and
a second bonding system formed on the second integrated circuit package device, the second bonding system including:
a second bonding system substrate; and
a second bonding element formed in the second bonding system substrate, the second bonding element comprising:
a second conduction component conductively connected to the second contact element, the second conduction component formed from a third metal; and
a second bonding component formed from a fourth metal;

wherein the first bonding component of the first bonding element is bonded to the second bonding component of the second bonding element to form a bond between the first bonding system and the second bonding system; and
wherein the first conduction component of the first bonding element is conductively connected to the second conduction component of the second bonding element to define a conductive connection between the first contact element of the first integrated circuit package device and the second contact element of the second integrated circuit package device.
