Magnetically sealed multichip integrated circuit package

摘要

A magnetically sealed integrated circuit package includes a substrate having a cavity for holding multiple integrated circuit die, a lid for covering the cavity to protect the die, a ferromagnetic seal ring which is fixed to the substrate around the die, and a magnet which is fixed to the lid and coincides in shape to the seal ring for magnetically attracting the seal ring to hold the lid in place when the lid covers the cavity.
