Patent ID: 8847112

Claim:
A laser-based processing method, comprising: providing a series of laser pulses characterized by a first pulse and at least 9 following pulses, where each laser pulse in the series is characterized by a spike/plateau chair laser pulse shape, and each pulse in the series is further characterized by a laser spot with a laser spot area; and removing a thin film of material, deposited on a substrate, along a pattern down to the substrate by: placing the laser spot of the first pulse through the substrate at a spot position on said thin film of material; and placing the laser spots of each of the following pulses in the series of pulses through the substrate at spot positions along said pattern on said thin film of material such that each spot position is adjacent to the spot position of the laser spot of the previous pulse, and there is an overlap of spot positions such that an area of each spot overlaps in some amount an area of each previous spot, wherein said laser pulse shape is configured such that no micro-cracks are formed in edges of the pattern in the thin film material.
