Abstract

PURPOSE:To obtain a fuse of high electrostatic dielectric strength and sure blowing by forming the fuse part of an ROM into a specific shape. CONSTITUTION:If the width in the central part of the fuse 2 of an ROM is narrowed to a taper shape or the like, the side area increases and electrostatic dielectric strength increases. Also, the fuse is blown surely from the narrow width part.
