Methods and apparatuses to design an Integrated Circuit with a shielding of wires. That is, the guide pipe is formed so that a route for transmitting an ultrasonic wave generated from the ultrasonic sensor may be tapered from this ultrasonic sensor toward a reflector plate. An insulating material is formed on the substrate and the base electrodes that separates the gate electrodes from the base electrodes, the gate electrodes formed on the insulating material. The public-key encrypting unit encrypts the random number by the public key in the storage unit, the random number generated by the random number generating unit after the debugging unit is disabled. The LED structure includes a Group IV-based substrate, an AlN nucleation layer formed on the Group IV-based substrate, a GaN epitaxial layer formed on the AlN nucleation layer, a distributed Bragg reflector multi-layer structure formed on the epitaxial layer, and an LED active layer formed on the DBR multi-layer structure.
