Abstract:
An integrated circuit package may be fabricated with a universal dummy device, instead of utilizing a dummy device that matches the bump layer of an electronic substrate of the integrated circuit package. In one embodiment, the universal dummy device may comprise a device substrate having an attachment surface and a metallization layer on the attachment surface, wherein the metallization layer is utilized to form a connection with the electronic substrate of the integrated circuit package. In a specific embodiment, the metallization layer may be a single structure extending across the entire attachment surface. In another embodiment, the metallization layer may be patterned to enable gap control between the universal dummy device and the electronic substrate.
