One super-resolution approach is called stimulated emission depletion (STED) microscopy. This technique uses a confocal microscope and a diffraction limited excitation beam that is …
As the flat panel display market moves from LCD to OLED display technology, laser patterning and cutting of heterogeneous materials (comprised of multiple organic material films) with …
Crystalline-Silicon solar cells are the predominant solar cell technology used in fabricating solar panels because of the availability of silicon, well-developed manufacturing processes, …
DUV technology for photolithography is exclusively based on projection optics since the pattern on the photomask is much larger than the final pattern developed on the photoresist.
This application note provides a brief overview of semiconductor manufacturing and describe the various optical techniques used to define, inspect, and measure feature sizes and layer …
Laser machining is a non-contact process that can achieve higher precision and quality, smaller features, improved consistency with no tool wear, and possesses the flexibility to machine …
Only when performing optimally can laser systems guarantee the most cost-effective production of high-quality components. Even the smallest deviations in beam adjustment or focal position …
Thermal imaging techniques involve discriminating between various objects in a scene based on their respective differences in temperature.
Unlike the pure optical microscopy techniques, PAM takes advantage of the weak acoustic scattering in tissue and thus breaks through the optical depth penetration limit (~ 1 mm) in …
Three-photon fluorescence (3PF) microscopy can provide a significant advantage over 2PF microscopy in strongly scattering samples such as the mouse brain.
Optogenetics combines genetic and optical techniques to selectively and specifically modulate signaling pathways in intact living organisms using light.
MALDI is a soft ionization technique used in mass spectrometry (MS) that produces rapid and efficient ionization of a wide variety of molecules.
Powder bed fusion systems utilize a heat source—such as a laser—to sinter or melt ultra-fine layers of material like powdered metal to fuse into the desired shape.
In vat polymerization systems—including stereolithography (SLA) and digital light processing (DLP)—a UV laser constructs an object in a vat of a liquid photopolymer resin by curing …
One technology which shows promise of meeting the growing demands of solar panel quantity, performance and cost-effectiveness is TOPCon, or tunnel oxide passivated contact, technol …
Ophthalmology is the branch of medicine that deals with the anatomy, physiology and diseases of the eye. The laser is particularly suited to ophthalmic surgery since it can provide …
LiDAR is an active remote sensing technique that is similar to RADAR but, instead of using radio waves as a radiation source, it uses laser pulses. In this technique, a laser source …
Lasers are routinely used in a variety of PCB manufacturing processes including via drilling, depaneling, profiling, laser direct imaging, repair, trimming, and marking. Laser processing …
In this application note, we provide a brief description of the basics of wafer and reticle inspection techniques and discuss the characteristics of current inspection tools.
Lithography is defined as "a method of printing from a flat surface (such as a smooth stone or a metal plate) that has been prepared so that the ink will only stick to the design that …
