…(< 1% rms), nearly perfect process control is achieved by
providing a large process window. The beam on the wafer must provide the same fluence over
its whole cross section - a flat-top beam is required. Furthermore, the exact shape of the beam
hitting the wafer in the LLO process…

…extends the range of possible target materials that can be used. Second, it enables a larger area on the target to be ablated with the desired fluence. In turn, this area enlargement increases the deposition rate and reduces the plume angle, resulting in higher deposition efficiency. Finally, higher…

…volume per pulse when the pulse fluence
is increased. The ablated volume per pulse is zero at the threshold fluence and increases with fluence but only
logarithmically. At a fixed output power, more volume can therefore be ablated if the energy fluence is
lowered, while simultaneously…

…pulse energy/peak pulse fluence (all other factors being fixed).
This typical curve has the peak ablation rate occurring at an optimum fluence that is usually equal
to 5 to 10 times the fluence required to begin ablating the material. Above the optimum fluence,
despite the higher…
