…Structured light is the projection of a light pattern (plane, grid, or more complex shape) at a known angle
onto an object.This technique can be very useful for imaging and acquiring dimensional information.The
most often used light pattern is generated by fanning out a light beam into a…

…by
patterning metal and dielectric layers that allows each silicon die to be connected to other
dies. In this way RDLs serve to re-route the input/output of a die.
Currently, many RDLs are structured using "photodefinable" dielectrics where the desired circuit
pattern is printed…

…to coat
a semiconductor wafer with a light-sensitive photoresist. A reticle (mask) containing the desired circuit pattern is illuminated with UV laser light and the
mask pattern is projected onto the wafer surface, after which the exposed resist is developed and the wafer is chemically…

…RDL using "photodefinable" dielectrics. These are photosensitive materials
that are lithographically exposed with the
desired circuit pattern and then wet-developed to remove either the exposed or
unexposed areas.
Unfortunately, photodefinable polymers are costly and the…

…excimer lasers
are used in mask-based direct patterning of microcircuits for
cost-sensitive applications like medical disposables. Here, the
excimer laser is used to pattern a very high volume of disposable
sensor circuits in thin metal on a flex substrate in a reel-toreel…

…integrated
circuit fabrication is inspection of
un-patterned wafers to identify
contaminants. Our Azure and
Paladin lasers, which employ
different types of specialised UV
DPSS technology, are utilised
for this application as well as
for patterned wafer…

…beyond annealing
low-temperature silicon, including maskbased direct patterning of microcircuits for
cost-sensitive applications like medical disposables, where every year 20 billion disposable sensor circuits are created in thin metal
on a flex substrate in a reel-to-reel process.…

…display and solar panel
manufacturing pose similar challenges in the machining and patterning of ultrathin panels and
integrated thin films. Laser cutting and drilling of printed circuit boards presents another
opportunity for ultrafast lasers to enable further miniaturization…

Several display types require a high-density pattern of silicon thin film transistors (``TFTs''). If this
silicon is polycrystalline, the display performance is greatly enhanced. In the past, these polysilicon
layers could only be produced on expensive special glass at high temperatures.…

…production processes for FPDs. These processes include drilling, cutting, patterning, marking and yield
improvement.
Microelectronics--advanced packaging and interconnects
After a wafer is patterned, there are then a host of other processes, referred to as back-end
processing,…

…unidirectional traveling-wave ring oscillator because standing-wave oscillators
typically exhibit spatial hole burning; a
standing-wave pattern cannot efficiently
use the gain located at the nodes of the
sinusoidal electric field. This NPRO geometry also exhibits a clever trick:…
