The new process uses excimer laser ablation to integrate via and RDL traces in one patterning process step, followed by seed layer deposition, plating and planarization processes.. We will explain in detail the new proposed integration flow and further demonstrate its technical robustness and commercial advantages..
Exploring the process.. Excimer micromachining processes typically use ablation technology to remove material from the substrate.. Ablation occurs when the laser beam's intensity passes a threshold value that depends on the material to be ablated and the wavelength of the laser (see table).. Figure 1: The advantages of the projection ablation ..

Laser ablation refers to the process of removing a certain portion of a material from the surface by high-intensity laser treatment.. It is widely used in many industrial settings, such as laser machining and drilling, and special coatings (e..g.., pulsed laser deposition), as it allows a controllable amount of energy in duration and dosage to be applied to the specific target area..

The characteristics of excimer lasers and the nature of ablation and etching processes are described.. The two kinds of laser ablation mechanisms, thermal and electronic, are discussed.. Thermal processes all rely on an intense laser pulse to heat a surface very rapidly.. Electronic mechanisms do not rely on heating.. Two of these quantum-type processes have been discussed widely.. In the first ..
