A method and device for performing a contention based random access procedure by a mobile communication terminal in communication with a base station. An encapsulation body of polymer-based material encapsulates a semiconductor device and bonding wires, and a concavity structure is patterned on the encapsulation body by imprinting, laser drilling, photolithography, dry etching, die sawing, or other surface patterning technologies. Additional applications include use in the treatment of multiple sclerosis either alone or in combination with another drug. Upon detection of a valid breakpoint, the debug circuitry substitutes a jump to a debug program instruction in place of the next normal application program instruction.
