An unprogrammed die is attached to a die package, and bond wires are attached between the die and lead fingers on the die package. A cavity in the die package allows the die to be configured, such as with a laser. The die is then tested and, if needed, etched to ensure the desired configuration. The die package is sealed, such as with a filler material or a lid to protect the configured die and bond wires. In one embodiment, the die and bond wires are fully exposed through the cavity. In another embodiment, only a minority portion of the bona wires are exposed through the cavity. The cavity can be formed either prior to or after attaching the die and bond wires to the die package.
