EV Group Introduces Roll-To-Roll Nanoimprint Lithography System For Biomedical, Optical And Flexible Electronics Applications

Electronics-research-001(Nanowerk News) EV Group (EVG), a leading supplier of  wafer bonding and lithography equipment for the MEMS, nanotechnology and  semiconductor markets, today introduced the EVG®570R2R—the industry’s first  roll-to-roll thermal nanoimprint lithography (NIL) tool.



Jointly developed with  the Industrial Consortium on Nanoimprint (ICON), helmed by A*A*STAR‘s Institute of  Materials Research and Engineering (IMRE), the EVG570R2R utilizes hot embossing  to mass-produce films and surfaces with micro- and nanometer-scale structures  for a variety of medical, consumer and industrial applications, including  micro-fluidics, plastic electronics and photovoltaics.  The first system has  been installed in IMRE’s Singapore facility, where it will be used by IMRE to  conduct industrial research on the potential uses for large-scale nanoimprint  patterning, as well as by EV Group for product demonstrations with prospective  customers.

EV  Group unveils the industry’s first roll-to-roll thermal nanoimprint lithography  tool, the EVG®570R2R, which mass-produces films and surfaces with micro- and  nanometer-scale structures for a variety of medical, consumer and industrial  applications, including micro-fluidics, plastic electronics and photovoltaics.
Roll-to-roll nanoimprint technology is an attractive approach to  manufacturing micro- and nano-scale patterns due to its low cost, continuous  high throughput and large-area patterning capabilities.  Hot embossing, which is  one method of implementing roll-to-roll patterning, is particularly well suited  for devices used in biological and medical applications due to its low cost,  high throughput, material flexibility and monolithic approach.  By partnering  with IMRE, EVG has been able to leverage IMRE’s core competencies in materials  science with its own expertise in temperature embossing and pressure uniformity  to develop the EVG570R2R, whose innovative imprint module design provides  excellent temperature and pressure uniformity for micro- and nanoscale  patterning on a broad range of materials.
“While roll-to-roll nanoimprint lithography holds much promise  in enabling a variety of new applications, previous efforts to develop the  technology lacked a holistic approach,” stated Professor Andy Hor Tzi Sum,  executive director of IMRE.  “As part of this new ICON project, IMRE is bringing  together technology innovators from across the ecosystem to help drive this  technology toward commercialization.  Companies like EV Group have been  instrumental in building the foundational tools and solutions needed to make  roll-to-roll nanoimprint a viable manufacturing process.”
The EVG570R2R is the latest addition to EV Group’s extensive  suite of nanoimprint products, which also include the EVG®770 automated NIL  stepper, the EVG®750 automated hot embossing system, the IQ  Aligner® automated  UV-NIL and u-CP systems, the EVG®510HE and EVG®520HE semi-automated hot  embossing systems, and the EVG®620 and EVG®6200 automated UV-NIL systems.
Paul Lindner, EV Group’s executive technology director,  commented, “With the EVG570R2R, EV Group now offers the largest imprint product  portfolio to support a wide variety of applications, including medical,  point-of-care diagnostics, flexible electronics, displays, solar, architectural  glass and other structured films, biotechnology, security and optics.  We are  very proud of this particular development and working with IMRE and the ICON  organization.  EVG is once again laser focused on turning its R&D efforts  into world-class production-ready solutions, and we look forward to seeing the  results.”

(JCN) – A*STAR’s Institute of Materials Research and Engineering (IMRE) and Cima NanoTech, a US multinational company, have signed an agreement to jointly work on new sustainable nanomaterials, processes and devices for transparent conductors used to make cheaper and more efficient electronics and organic solar cells.

IMRE and Cima NanoTech are collaborating to develop new transparent conductive materials and components, based on Cima’s SANTE(TM) Technology and IMRE’s know-how in printed electronics. These innovations will enable efficient conductive interfaces with high transparency, which can be developed into low cost and high performance products for displays, organic solar cells, and flexible electronics.

Conventional Indium Tin Oxide (ITO) and Transparent Conductive Oxides (TCO) used in today’s solar cells, OLEDs, flat panel TVs, and touchscreen displays have limitations in conductivity, flexibility, and cost. These new materials and processes that IMRE and Cima are developing will potentially enable faster response touch screens for large flexible displays and reduce production cost.

“Cima is particularly interested in IMRE’s extensive electronics materials systems and device fabrication capabilities, said Mr Jon Brodd, Cima NanoTech’s Chief Executive Officer (Singapore). IMRE and CIMA are working together to develop enabling nanotechnology materials, components, and processing methods to support new market applications in transparent conductors and printed electronics with SANTE, Cima NanoTech’s self aligning nanoparticle network.

“We are collaborating with Cima to develop new transparent conductor applications that will lead to cheaper, flexible, more eco-friendly and sustainable products,” said Dr Zhang Jie, the key scientist leading IMRE’s printed electronics initiative. The research team will develop applications using novel, sustainable transparent conductor materials as an alternative to conventional ITO-based materials.

“Innovations in materials R&D are crucial in evolving today’s devices into new products with tomorrow’s technology. IMRE’s research portfolio covers the entire printed electronics value chain that includes materials, processes, optimisation and reliability testing for integrated printed electronics prototypes. I am glad that we can present a diverse suite of capabilities in partnering Cima in the area of transparent conductors and printed electronics,” said Prof Andy Hor, IMRE’s Executive Director.
