Abstract: A set (50) of laser pulses (52) is employed to sever a conductive link (22) in a memory or other IC chip. The duration of the set (50) is preferably shorter than 1,000 ns; and the pulse width of each laser pulse (52) within the set (50) is preferably within a range of about 0.1 ps to 30 ns. The set (50) can be treated as a single “pulse” by conventional laser positioning systems (62) to perform on-the-fly link removal without stopping whenever the laser system (60) fires a set (50) of laser pulses (52) at each link (22). Conventional IR wavelengths or their harmonics can be employed.

Abstract: A method of forming a scribe line having a sharp snap line entails directing a UV laser beam along a ceramic substrate such that a portion of the thickness of the ceramic substrate is removed. The UV laser beam forms a scribe line in the ceramic substrate in the absence of appreciable ceramic substrate melting so that a clearly defined snap line forms a region of high stress concentration extending into the thickness of the ceramic substrate. Consequently, multiple depthwise fractures propagate into the thickness of the ceramic substrate in the region of high stress concentration in response to a breakage force applied to either side of the scribe line to effect clean breakage of the ceramic substrate into separate circuit components. The formation of this region facilitates higher precision breakage of the ceramic substrate while maintaining the integrity of the interior structure of each component during and after application of the breakage force.

Abstract: Terminating the ends of passive electronic components entails applying a laser-removable coating to one or both of the opposed major surfaces of a substrate. A UV laser beam having a spot size and an energy distribution sufficient to remove the laser-removable coating from multiple selected regions of at least one of the major surfaces to which the laser-removable coating was applied is directed for incidence on the substrate. Relative motion between the UV laser beam and substrate effects removal of sufficient amounts of laser-removable coating to expose the multiple selected regions. The substrate is then broken into multiple rowbars or individual components, each of which includes side margins. An electrically conductive material is applied to the side margins to form electrically conductive interconnects between portions of the side margins spatially aligned with the multiple selected regions.
