Testbeds
System level test-beds are public-private partnerships designed to transfer promising fundamental discoveries and developments from the research laboratory to viable manufacturing platforms that can be adopted by industry. The NNN is taking a close look at some of these collaborations from our affiliate research centers.

Hierarchical Metal Oxide Films

NSF Center for Hierarchical Manufacturing (CHM), University of Massachusetts Amherst Patterned metal oxide films having well-defined order and morphology are essential device layers in microelectronics, photovoltaics, and microfluidics for separations and sensors.  In a typical fabrication process sequence, a planar metal oxide film is deposited, coated with multi-layer resist structures, patterned by optical lithography, etched, stripped, ashed, and cleaned to generate a patterned oxide film.  This cycle often consists of 10 or more process steps.  Moreover, the resolution of current lithography and etch techniques limit the minimum feature size precluding the direct fabrication of complex geometric structures.

Plasmonic Imaging Lithography

NSF Center for Scalable and Integrated NanoManufacturing (SINAM), University of California Berkeley  In order to leverage the dramatic advancements in nano-scale science and engineering, there is an urgent need for versatile, high-throughput nanofabrication technologies that are adaptable to frequent design changes. Commonly used mask-less nano-lithography methods, such as electron-beam, focused ion-beam and scanning-probe lithography, can provide the desired flexibility, but prove to be rather limited by their throughput, mainly due to their slow scanning capabilities.

Self-Assembled Polymer Templates for Device Applications: High-Rate and Low-Cost for Roll-to-Roll Processing

NSF Center for Hierarchical Manufacturing, University of Massachusetts AmherstThe rapid generation of highly-ordered arrays of nanoscopic elements with periodicities of <30 nm render the self-assembly of block copolymers (BCPs) ideal scaffolds and templates for nanofabrication. However, several crucial limitations to enable a broad-based adaptation of BCPs in nanomanufacturing must be addressed in order to demonstrate viability of this approach through well-defined product-oriented outcomes. Based on the approach of BCP templating, the focus of this testbed element includes the production of high-volume, cost-sensitive products (e.g., organic electronics, photovoltaics, energy storage, and flexible displays) that require high-rate processing, low materials cost and an ability to functionalize or modify the BCP template.
