…the excimer laser line beam of a 308 nm wavelength is shown through the carrier glass substrate on the polymer. Only the polymer in the direct vicinity of the glass substrate is evaporated, as illustrated in Figure 2. LLO separation using the 308 nm excimer laser occurs within a single laser pulse…
…unterschiedlichen Excimerlaser-Leistungsklassen zielgenau anpassen und für diverse Substratgrößen und benötigte Durchlaufzeiten kosteneffizient auslegen. Laser mit infraroten oder sichtbaren Wellenlängen eignen sich dagegen nicht, da durch diese sehr viel Wärme in den Verbundwerkstoff eindringt. Der…
Goettingen. The amorphous starting material melts
and crystallizes right behind the laser line the
polycrystalline silicon layer. This recrystallization
process is known as excimer laser annealing.
The throughput of a Vyper/LineBeam-system is
about 15,000 square meters…
…excimer laser parameters that impact this application and see how the reality and perception of the excimer have evolved to the benefit of both the ophthalmic surgeon and the patient. Laser refractive surgeries have long used deep ultraviolet (193 nm) pulses from an argon fluoride excimer laser to…

Such requirements can be fulfilled with compact and
affordable low power excimer lasers. The Coherent
COMPexPro excimer laser family is an ideal source for
thin wafer laser debonding. It provides up to 20W…
…in producing excimer lasers for industrial and scientific
applications. Here we interview company General Manager Richard Waldermann on the current state of excimer lasers and their future prospects.
