DARPA funds partnership between Singapore's Institute of Microelectronics and University of Washington for triple boost to miniaturization efforts
(Nanowerk News) Advances in miniaturisation have led to the increasing adoption of microsystems in a wide array of applications. Continued miniaturisation, however, impacts the assembly of the components, the integration of passive components and overall system performance. To address these challenges, the Defense Advanced Research Projects Agency (DARPA) is funding a research collaboration between the Institute of Microelectronics (IME), a research institute of the Agency for Science, Technology and Research (A*STAR) and University of Washington's (UW) Department of Electrical Engineering. The partnership will result in the development of a parallel assembly technique to accurately and efficiently assemble ultrathin chips; a three-dimensional (3D) Micro-Electro-Mechanical-Systems (MEMS) high density capacitor with increased energy storage for portable systems; and a microsensor that detects human dehydration levels.
The research on parallel assembly techniques aims to develop a self-assembly process for repeatable high yield results, countering the common issues that often arise from assembling ultra-small chips. Such issues include the difficulty in the mechanical handling of ultrathin devices, and the reduced efficiency of conventional 'pick and place' techniques. The proposed method will be based on shape matching and will consist of pattern design, chip and substrate fabrication, chip dicing, palletisation, self-assembly and gang bonding.
This collaboration will also develop 3D micro capacitors with significantly increased energy storage density, low leakage, and an extended stable lifetime, which will be indispensable for implantable microsystems. An innovative multilayer, high aspect-ratio nano-structured design is being developed to enhance the capacitance value, and thus the energy storage density, through a substantial increase in the effective area of capacitor plates.
Finally, the joint effort on the dehydration microsensor will work towards enhancing human functionality in situations where access to drinking water may be unavailable or impractical. Detection of early signs of dehydration prior to the actual onset of symptoms will be critical to preventing such heat-related fatalities. The proposed biosensor microsystem will feature a novel configuration where the salivary flow rate can be assessed by an impedimetric analysis.
IME will provide expertise in the development, simulations and early stage fabrication for these developments, while UW will contribute lab-scale process development and theoretical analysis on the parallel assembly technique project and review with guidance consultation on the rest.
Professor Dim-Lee Kwong, Executive Director of IME, said, "These projects mark a promising start to a long-term relationship with the University of Washington and DARPA, both known for their distinguished accomplishments and tradition in excellence."
Prof. Karl Böhringer from UW noted, "With IME's recognised capabilities and expertise in development for industry and beyond, we are confident that our collaborations will come to fruition with pioneering results."
