Gratings of Regular Arrays and Trim Exposures (GRATE)
Abstract
The Gratings of Regular Arrays and Trim Exposures (GRATE) program will develop revolutionary circuit design methodologies combined with hybrid lithography tools to enable cost-effective low volume nanofabrication for DoD applications. Moore's law has driven the silicon industry for several decades with the minimum feature size on an integrated circuit (IC) reduced to 22 nm for today's commercial products. Due to challenging patterning requirements and complex circuitry, the costs of circuit design and verification, lithography tools and masks, and testing costs have increased exponentially and are unaffordable for low-volume manufacture of application specific integrated circuits (ASICs) for military electronics. Consequently, military electronics capabilities are currently limited by the high cost of nanofabrication. To solve this important problem, DARPA has invested in a variety of maskless patterning technologies including parallel e-beam arrays, parallel scanning probe arrays, and an innovative e-beam lithography tool. This program will develop revolutionary circuit design methodologies coupled with innovative fabrication techniques and hybrid maskless patterning tools to realize cost-effective nanofabrication for low-volume defense or commercial ASICs. Such an approach can also address the nanofabrication requirements of other low-volume DoD technologies such as photonics and micro-electro-mechanical systems. This program will transition via industry.
