There is provided a voltage regulator suitable for a CMOS circuit. The platform includes a platform hardware, which may verify the contents of the IO device. A rear panel has a rear panel front sheet and a rear panel back sheet. In another aspect of the invention, a method for processing a semiconductor device is provided. That is, when the flag of a qnode structure is observed to be in a certain state, the thread represented by that qnode structure acquires that lock. The first and second magnetic field detection sensors have two pairs of multi-layered magnetoresistive effect elements.
