Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

Abstract: The present invention relates to a method of updating a new BIOS image of a BIOS ROM in a portable computer in a production line. The present invention comprises the steps of: determining whether the computer system is being powered only by a battery; determining whether the battery level is above a reference level when the computer system is powered only by the battery; updating a BIOS ROM by means of a flash utility program when the computer system is powered only by the battery and the battery level is above the reference level.
