2015 marks the 50th anniversary of Moore's Law, an "observation" that has ruled the development of semiconductor manufacturing since Intel co-founder Gordon Moore first published his ideas about the e...
xponential advance of integrated circuits. The mantra of "smaller, faster, cheaper, and more powerful" has guided the industry for the past five decades, and despite nearing the physical limits of silicon-based technologies, we continue to push ahead with new innovations that keep Moore's Law moving.
Photolithography, the process that images circuit patterns and connections on silicon, is a critical enabling technology that moves Moore's Law progress. The key challenge for chip makers like Intel is how to make patterns with features smaller than the wavelength of light itself. Without technical advances, chip makers could not achieve the proper focus needed to make these microscopic structures hundreds of times smaller than the width of a human hair.
