A method and apparatus is provided to debug using replicated logic. A pair of anti-fall hooks is formed at a tip portion of the mounting surface to support a front edge portion of the work unit so as to prevent the work unit from falling off the mounting surface. Through the increase in the water content in the fluid, a shift in the reaction equilibrium takes place and consequently a cleavage of the 2-methyl-1,3-dioxolane present into ethylene glycol and acetaldehyde takes place. If the third actual terrain data point is above a line interconnecting the first and second actual terrain data points, the first actual terrain data point is modified such that the third actual terrain data point is not above a line interconnecting said modified first actual terrain data point and the second actual terrain data point. In a variation thereof, an electrical fuse is formed which includes a continuous silicide region through which a current can be passed to blow the fuse. Both sections can be placed in a protective material.
