…the laser beam onto the
ceramic surface in real time, in order to compensate
for package height variations. Because of their more
reliable interaction with ceramic materials, DPSS lasers
based on Nd:YAG, which offer high pulse energies and
relatively long pulses, are often…

…hazardous lithography chemicals. Because of these benefits, CO 2 lasers have been used extensively for drilling vias in microelectronics packaging applications for some time. However, the long infrared wavelength of CO 2 lasers limits their minimum focused spot size (due to diffraction). The result…

…single excimer laser application in terms of unit volume. What started with crude experiments on pig eyes has now evolved to more than 10,000 high-precision, compact, tabletop lasers deployed worldwide at eye clinics and LASIK centers. In the LASIK procedure, excimer laser pulses at 193 nm are used…
