A photothermal model of ablation is used to investigate the time scales for polymer degradation by UV laser light. In the absence of a significant incubation effect, strong absorbers (e.g., polyimide) are expected to decompose roughly three orders of

Primary sputtering mechanisms are conventionally grouped in terms of the categories collisional, thermal , and electronic . With pulsed photons one must. in addition, consider the emission of droplets and fragments in thermomechanical processes. Puls

The laser-pulse sputtering of polymers should have two limiting cases. In the one there is ongoing release of particles from the target surface, the particles then form a Knudsen layer (KL), and there is finally an unsteady adiabatic expansion (UAE)

The term ‘‘incubation pulses’’ is applied to the pulses of ultraviolet laser radiation which are directed initially at a polymer surface and which etch less depth per pulse than subsequent pulses which remove identical depths of material at e

The etching of polymethyl methacrylate (PMMA), by pulsed ultraviolet laser radiation [20‐ns full width at half maximum (FWHM), 193 nm] can be increased more than threefold by overlapping both spatially and temporally laser pulses of 308 nm (20 ns F

Pulsed, ultraviolet radiation from an excimer laser with wavelengths of 193nm or 248nm, a pulse width of about 20ns, and fluences above a threshold value causes the ablation and etching of the surface of solid polymethyl methacrylate. The reaction wh

Excimer laser pulses with wavelengths of 248 and 308 nm were used to selectively seed Pd on SiO2 surfaces, making them suitable for electroless plating. This novel seeding process for insulating materials is accomplished with the sample immersed in t

When polymers are sputtered with 248 or 308 nm laser pulses there are two generically different responses. The most straightforward is where the emitted particles expand outwards away from the target surface obeying, in so doing, the laws of one‐di

The sputtering of polymer films with 248 or 308 nm laser pulses causes two groups of particles to be emitted. Light particles are emitted more rapidly and escape to form a shock wave. Heavy particles are emitted more slowly and under some conditions
