Abstract
An implantable cardiac defibrillator is provided. The implantable cardiac defibrillator includes a can, a storage cell for powering the defibrillator, and a circuit module disposed in the can for controlling the defibrillator. The circuit module has a first substrate, a first die coupled to the first substrate, a second die, and a second substrate coupled to and disposed between the first die and the second die. The second substrate has a first plurality of conductors to carry electrical signals to and from the first die and a second plurality of conductors to carry electrical signals to and from the second die. The die may be any of a number of types of electronic components, such as power transistors, memory chips, or others. The stacking of the die saves board space, allowing for further miniaturization or incorporation of additional electronic components.
