A plurality of pulses each having relatively low energy are consecutively applied to a subject fuse to cause breakdown, wherein the total energy of pulses is set in light of a prescribed breakdown threshold, which is calculated in advance. The subject fuse has a pair of terminals and an interconnection portion that is narrowly constricted in the middle so as to realize fuse breakdown with ease. A pulse generator generates pulses, which are repeatedly applied to the subject fuse by way of a transistor; then, it stops generating pulses upon detection of fuse breakdown. Side wall spacers are formed on side walls of fuses, which are processed in a tapered shape so as to reduce thermal stress applied to coating insulating films. In addition, pulse energy is appropriately determined so as to cause electro-migration in the subject fuse, which is thus increased in resistance without causing instantaneous meltdown or evaporation.

In a surface-area light source device, a light entrance side surface of a light guide plate of a surface-area light source device has a staircase shape having steps in the vertical direction, and light emission diodes are provided at each step. The structure enables the distance between a light emission diode provided at one step and light emission diodes provided at an adjacent step to be maintained greater even if the thickness of the light guide plate is reduced so as to decrease intervals of the light emission diodes in the direction of the thickness of the light guide plate.
