Abstract
A semiconductor integrated circuit according to the invention includes a wiring member formed on a main face of a semiconductor substrate, a fusing member connected to the wiring member and having a predetermined thickness, a barrier member for covering a bottom face and a side face of the fusing member, a light absorbing member for covering at least a side face portion of the barrier member for covering the fusing member, and an insulating member for embedding the wiring member, the fusing member, the barrier member and the light absorbing member. A complex permittivity of the light absorbing member is provided with a real part smaller than that of the fusing member in absolute value and an imaginary part larger than that of the fusing member.
