Patent ID: 7041516

Claim:
A method of assembling at least a first integrated circuit and a second integrated circuit into a multi chip module, the method comprising the steps of: attaching and electrically connecting the first integrated circuit to a first substrate to form a first assembly, testing the first assembly to ensure that it functions properly, attaching and electrically connecting the second integrated circuit to a second substrate to form a second assembly, testing the second assembly to ensure that it functions properly, and attaching and electrically connecting the first substrate to the second substrate to form the multi chip module, where the first substrate is attached and electrically connected to the second substrate by slotting the first substrate onto the second substrate, where the first substrate forms a horizontal slot that is bounded above by an upper surface of the first substrate and bounded below by a lower surface of the first substrate, and the slot receives a thinned portion of the second substrate, thereby creating electrical connections between the first substrate and the second substrate when the thinned portion of the second substrate is completely inserted into the slot of the first substrate, and the first substrate and the second substrate are disposed within a substantially common plane.
