Significant challenges exist for nanomanufacturing processes to gain acceptance within various industries, due in part to a mature infrastructure and supply chain, as well as potentially high capital expenses for technologies that might supplant existing tools and processes. While these issues are present in most sectors, the semiconductor industry is an prime example of an area where critical need must be demonstrated to justify the costs of replacing a substantial existing infrastructure. For example, optical lithographic tools enable patterning techniques that will only carry the industry for a few more years, after which no proven optical solutions exist to maintain progress within the constraints of the present roadmap. As a result, the International Technology Roadmap for Semiconductors (ITRS, 2009) includes both nanoimprint and directed self-assembly (DSA) patterning as part of the future roadmap for patterning solutions. 
Techniques to align CNT networks in-plane on a substrate have been investigated as a means to enable CNT-based electronic devices including transistors ad interconnects. One approach—transferring CNT thin films from one surface to another via a soft lithography—suffers from limited ability to achieve good adhesion of the CNT films to the transfer substrate and imprecise alignment of the CNT patterns. Ultimately, a transfer technique that can be scaled to large area with high throughput processing at low temperature is required to achieve flexible substrates for many emerging display, lighting, and solar PV applications. Pint et. al. report a scalable means to create aligned CNT thin film patterns on both rigid and flexible substrates. 
The National Center for Manufacturing Sciences has released the report from its third, NSF-funded, nation-wide survey gauging the momentum of nanotechnology develoment and depoloyment in the U.S. manufacturing industry. The survey targeted senior executives in U.S.-based manufacturing and research organizations and addressed pre-competitive and strategic issues influencing their organizations' nanotechnology commercialization initiatives. The goals of the survey were to identify and highlight trends in nanotechnology tech transfer and to make recommendations to accelerate product development and competitiveness.
