A semiconductor integrated circuit is capable of filling the need for more memory space through the effective use of an already-designed core block. At least so far as light falls within a half-intensity-angular-range, the light satisfies Condition 1 >1 except for light in the vicinity of a normal direction of the emission control face) and Condition 2. Furthermore, a passivation layer is provided, which covers the top side and the edge sides of the intermediate layer whilst leaving the chip contact area free. In addition, the method decrypts the encrypted message to a readable message when the first mobile phone receives the encrypted message, and displays the readable message on a display screen of the first mobile phone.
