Abstract: Provided are a fuse box that simultaneously prevents damage caused by laser blowing and cross talk between the fuses and a method of manufacturing the same. In a fuse box having an open region in which fuses are opened by laser blowing and a bundle region in which fuse opens do not occur, a capping layer, adjacent to the open region, having a metal layer and an insulation layer covers the outermost fuses in the bundle region, thereby reducing the influence of laser blowing of fuses in the bundle region, and preventing capacitive coupling caused by the formation of a parasitic capacitor between fuse lines and an insulation layer therebetween. Accordingly, cross talk due to the capacitive coupling can be prevented, thereby enhancing the reliability of a fuse circuit. Lower fuses can be disposed in a lower layer in the bundle region, thereby forming a two-layered fuse box.

A fuse focus detector including first and second conductive layers may be formed in a scribe line region.

For a laser repair method, a target region may be divided into sub-regions. In one selected sub-region, the fuse focus detector may be laser scanned in a direction for a reflection light measurement providing information on a thickness of the fuse focus detector. Using the thickness information, a focus offset value of a fuse in the selected sub-region may be calculated. When the focus offset value is within an allowable range, fuse cutting may be performed.

Abstract: A disc loading method for an optical disc apparatus, wherein, where a disc having a reproduction-only area is loaded in the optical disc apparatus, if signal quality of the reproduction-only area of the disc is acceptable, a signal adjustment operation on this reproduction-only area is skipped so as to shorten the lead-in time needed for signal adjustment.
