…for this process is to use a smaller size beam and raster scan that
across the wafer. In this case, special consideration is given to the shape and size of the beam
in order to match with the laser and the device wafer. A typical beam shape as used in our
UVblade system is e.g.…

…in critical line beam
shaping optics for excimer laser annealing tools for display fabrication.
Freeform optics
Aspheric/freeform optics manufacturing has become a main theme in the optics
community over the last 12 months.
Defined as surface shapes that lack rotational…

to produce the required line beam shape.
Moreover, the details of the beam profile
(e.g., linearity, uniformity) have a major
impact on process throughput and, hence,
cost. To this end, Coherent developed strategic partnerships with beam delivery experts, and also brought…

…as the COMPexPro (Fig.6) deliver
a high energy pulse that is naturally rectangular in
shape with uniform intensity distribution. This beam can
readily be manipulated with beam shaping optics to
match the necessary processing area on the work
piece, and to have a homogeneous…

The CleanWeld solution for this again involved utilizing a dedicated intensity distribution in the
focused laser spot. The optimized beam shape allows the part to be both pre- and post-heated,
thus avoiding problems caused by rapid part cooling. It also eliminates spatter and the need…

…of each of the four beams
enables the separation between the staggered beam spots (see figure 3) to be varied from zero (i.e., co-aligned) to ±250µm.
The x and y ellipse dimensions can also
be independently adjusted for each wavelength. Thus, the shape, size and position
