Chip Makers Weigh Benefits and Costs of Laser Marking Systems
In the fledgling days of the semiconductor industry, chip makers encoded serial numbers and dates on integrated circuit packages using conventional pad printed or ink-jet techniques. These methods offered users a high-contrast mark at a relatively affordable cost, but they also resulted in fumes, occasional smudging and the tedious task of refilling vast ink reservoirs. As incidents of...
Optical Design:
As the market for photonics has spread into new and varied applications, the number of optical engineers has not kept pace. A growing number of manufacturers are finding themselves dependent on the...
Machine Vision Offers User-Friendly Error Detection
As semiconductors continue to become more complex, and manufacturers look for ways to improve their processes, machine vision is creeping into more places in the production chain. Acting as the...
Image Is Everything
In choosing image sensors, charge-coupled devices (CCDs) have long been the benchmark for image quality, offering significantly higher resolution than their competitors. But manufacturers are making...
Photonics Will Assist Next Lithography Tool
Surely someday will find an end to Moore's Law, which says the number of transistors on a semiconductor chip will double every 18 months. Pundits have been predicting an end to this frenzied...
Optical Networks Seek Reconfigurable Add/Drop Options
The ability to add and drop wavelengths from dense wavelength division multiplexing systems is a key function. Accomplishing this task optically, rather than electrically, is an exciting challenge...
Photonics-Based Technologies Improve Semiconductor Yield
The silicon wafer, the basic unit of material in the semiconductor industry, encounters a range of processing techniques, such as crystal growth, ion implantation, film deposition, lithography, etch,...

Scientists Propose Design Strategies for Two-Photon Absorption
The principle behind two-photon-excited fluorescence microscopy is simple: In the presence of laser pulses, molecules simultaneously can absorb two or more photons at longer wavelengths with the same effect as absorbing one photon at a much shorter wavelength. Unfortunately for science, most known organic molecules have a relatively small photon absorption cross section, and the criteria for...
New Telescope Makes the Stars Wheelchair-Accessible
In the summer of 1995 the University of Illinois made many of its campus facilities wheelchair-accessible, including the observatory on the roof of the library. It wasn't until a year later, however,...

VXcientists recently got their first glimpse of the oldest, most distant galaxies in the universe from images sent back from the Hubble Space Telescope. A sensitive IR camera detected the faint glow...
Laser Interactions Create Powerful Magnetic Fields
Intense laser pulses, which possess strong magnetic and electric fields, can force the electrons in a plasma to oscillate dramatically. It is this unique interaction, which also produces very high...
Nanoshocks Reveal Molecular Behavior
What is the first step in an explosion? In energetic materials, the question focuses on the dynamics of molecular behavior. Empirically, we know that we can break bonds and make energy, but how does...
