…angled features (FIGURE 3).
Seed metal removal
Another unique advantage of excimer laser
ablation is that it does not affect copper or
aluminum layers above 1µm thick. But conductive layers thinner than about 500nm
are easily ablated. This inherent behavior
can be…

of the excimer laser produced ta-C films on steel substrates was not sufficient for some applications,
intermediate layers were employed. Best adherence was obtained with boron carbide and tungsten carbide
(WC) intermediate layers, which are also deposited by excimer laser ablation

…Here, the laser is projected through a mask
containing the desired pattern to be produced, and the substrate (which is larger than the
projected pattern) is ablated, moved, and then ablated again, until all the desired areas have been
patterned. Excimer laser ablation is a…
