Project Title: Nano-Imprint Lithography Infrastructure for Low Cost Replication at the 65nm Node and Beyond

Short summary: Design and demonstrate technology for step and flash imprint lithography (S-FIL™), a novel method of transferring integrated circuit patterns to the surface of a semiconductor wafer by molding of three-dimensional features potentially as small as 20 nanometers or less.

Project duration: 5/1/2004 - 4/30/2007
Total project (est.): $36,790,485.00
Requested ATP funds: $17,623,118.00

Overall Objectives
----------------
Step and Flash Imprint Lithography is a step and repeat nano-pattern replication technique with sub-20nm resolution capability that has the potential to lead to a low cost, high throughput process. It possesses important advantages over photolithography (PL) and other next generation lithography (NGL) techniques since it does not require expensive optics, advanced illumination sources, or specialized resists that are central to PL and NGL technologies. This proposed research seeks to mitigate the technology risks associated with the implementation of S-FIL at upcoming key semiconductor technology roadmap nodes (ie: 65nm node, 45nm node, and beyond).

Molecular Imprints, Inc. (MII) has put together a NIST-ATP team to develop S-FIL technology for CMOS fabrication at the 65nm node and beyond. MII will lead the joint venture and the partners are: Motorola, KLA-Tencor, Photronics, and University of Texas at Austin. This team will have the ability to address all the key technical risks associated with developing a complete infrastructure for the integration of S-FIL technology into microelectronics fabrication at the 65nm node and beyond.

Detailed Program Goals:
-------------
Demonstrate feasibility of patterning at the 65nm nodes and beyond using step and flash imprint lithography with appropriate overlay alignment accuracy, throughput, CD control and process yields. A particular theme of the project will be to address the patterning of dense contacts. Dense contacts represent a critical lithography level where most new (shorter wavelength) lithography technologies are introduced. Therefore, the value of the S-FIL technology can be evaluated by attempting to pattern dense contacts without introducing forbidden pitch structures that are encountered in sub-wavelength optical lithograph.

The joint venture partners and their roles are:
