…section of the through
glass vias. A more thermal process would
cause the glass to fracture. Using an excimer
laser wavelength of 193 nm at higher fluences
(several Joules per square centimeter)
could extend this same method down to via
diameters of 10 µm.

…lasers
with the requisite output power for these singulation
applications. The 40W Coherent AVIA NX is a nanosecond
pulsewidth, UV solid- state laser that is already widely
employed for semiconductor package cutting. Coherent
also offers higher power AVIA NX lasers than this…

…can produce several discrete wavelengths throughout the UV; depending on the gas
combination, emission ranges from 157 to 348 nm. The deep-UV line at 193 nm is the most widely used source for lithography processes in the semiconductor
industry. The 308-nm wavelength is used for annealing…

gas laser technology used in laser refractive surgical applications (LASIK). These
procedures use the unique deep ultraviolet
(193 nm) pulses from an ArF (argon fluoride) excimer laser to perform computercontrolled spatially selective ablation of
corneal tissue. The deep…
