Progress in Nanosystems for Computing and Health
The ubiquitous capture, digitization and integration of health data remains a grand challenge, promising to dramatically impact how we understand, diagnose and treat disease. To realize its full potential, the underlying electronics must be able to capture an increasingly diverse range of data from a wide variety of potential sources (e.g., measuring detailed chemical composition of breath from thousands of distinct chemical sensors). Yet simply capturing massive amounts of raw data from various aspects of our biology is insufficient; this raw data must then be processed on in order to transform it into useful information. Unfortunately, such systems finely-integrating thousands of sensors with compute and data storage are currently infeasible, as the materials and technologies leveraged to fabricate conventional computing, data storage, and sensing are often distinct and thus cannot be fabricated on the same chip.
Therefore, to enable radically new electronic systems for capturing and integrating ubiquitous health data, new technologies are required. For instance, carbon nanotubes (CNTs), are cylindrical nanostructures composed of a single sheet of carbon atoms and have exceptional electrical, physical, and thermal properties. They can be used to fabricate CNT field-effect transistors (CNFETs), which are promising candidates for enabling both the next-generation of highly energy-efficient computing systems as well as ultra-sensitive sensors. Projections based on calibrated experimental measurements predict electronic computing systems fabricated from CNFETs can achieve over a 10× benefit in energy-efficiency versus the same system fabricated from today’s conventional technologies. Moreover, CNFETs have demonstrated world-record chemical sensitivity with single molecule detection limits for a wide range of analytes. Importantly, since both sensors and compute can be fabricated from the same nanomaterial, a future CNFET-based technology promises a path for integrating both sensing and computing within a single chip, a major challenge for electronics today.
Despite this promise, CNFETs have only been realized in academic or research laboratories, and thus there remains an important disconnect between the promise of CNFETs and realizing this potential. Even with recent progress, there are still many challenges prohibiting the realization of CNFETs within commercial manufacturing facilities. These include meeting manufacturing requirements (scalable to large-area ≥200 mm industry-standard substrates and high throughput while minimizing cost), compatibility requirements (leverage and repurpose existing equipment within these facilities, and not introduce prohibited chemical contaminants or particulates within these highly-regulated nanofabrication facilities), and performance requirements (enable a CNFET technology that can realize highly sensitive sensors as well as highly energy-efficient computing systems). In this talk, I will show how my recent work has addressed all of these major concerns, culminating in the commercial adoption of CNFET technologies within multiple commercial manufacturing facilities: both a major semiconductor manufacturing company as well as a major U.S. foundry. This represents the first adoption of a beyond-silicon emerging nanotechnology for highly energy-efficient computing within commercial fabrication facilities and paves the way for realizing a radically new generation of powerful electronic systems that promise to change the way we capture and process massive volumes of data for healthcare applications and beyond.
