Direct laser patterning of various materials has found its way into several micro-system production lines like inkjet printing, solar cell technology, flat-panel display production, semiconductors and medical treatment. Typically, TEM00 single-mode solid state lasers and their higher harmonics are used, especially for machining of holes and trenches....$28.00

Keming Du, EdgeWave GmbH; Wurselen Germany
Presented at ICALEO 2009
Structuring and patterning of thin layer via selective laser ablation is one of the key technologies in production of display and photovoltaic. Concurrently, there are two ablation processes used in production of thin film solar: Scribing via selective ablation and edge isolation via deletion. Beside the wave length, the pulse length and the peak power, the beam profile of the laser is of essential importance for the efficiency of the ablation process and for the productivity. The most currently...$28.00

Presented at ICALEO 2009
Silicon is widely used in a number of industries but primarily in solar cells and in semiconductor manufacture, with growing applications in jewelry and entertainment goods. In the majority of applications the source material is in the form of wafers which are typically 0.2-1.5mm (thick and 100-300mm diameter. From the flat faces of the octagons they laser cut a flat rectangular wafer that is then further processed to become a solar cell. Cutting speed and yield are important ...$28.00

The water jet-guided laser technology has found a broad range of applications in the micromachining field. Its principle is to focus a laser beam into a hair-thin, low-pressure water jet, onto the sample. This hybrid system prevents heat damage to the material by cooling the cutting edges in between the l...$28.00
