Some time ago, someone posed this question to me: “What comes after the computer chip?” Having spent most of my career on advancing semiconductor technology, which is the physical foundation of the computer chip, I find this question worth thinking about. So I wrote this blog on Slate.
RESEARCH AREAS: Nanotechnology, nanoelectronics, semiconductor technology, solid-state devices, Si CMOS, solid-state imaging.
21st century information technology (IT) must process, understand, classify, and organize vast amount of data in real-time. 21st century applications will be dominated by data-centric computing operating on Tbytes of active data with little data locality. At the same time, massively redundant sensor arrays sampling the world around us will give humans the perception of additional “senses” blurring the boundary between biological, physical, and cyber worlds. Abundant-data processing, which comprises real-time big-data analytics and the processing of perceptual data in wearable devices, clearly demands computation efficiencies well beyond what can be achieved through business as usual.
The key elements of a scalable, fast, and energy-efficient computation platform that may provide another 1,000× in computing performance (energy-execution time product) for future computing workloads are: massive on-chip memory co-located with highly energy-efficient computation, enabled by monolithic 3D integration using ultra-dense and fine-grained massive connectivity. There will be multiple layers of analog and digital memories interleaved with computing logic, sensors, and application-specific devices. We call this technology platform N3XT – Nanoengineered Computing Systems Technology. N3XT will support computing architectures that embrace sparsity, stochasticity, and device variability.
[N3XT: Nano-engineered Computing Systems Technology. Monolithic 3D integration of memory immersed in logic, connected by ultra-dense vertical connections.]
For transistors it is important to have an atomically thin channel that enables gate length scaling while maintaining good carrier transport required for a high current drive. At the same time, parasitic resistance from the contacts and parasitic capacitance from the device structure must be minimized. Currently, we are working on the use of carbon nanotube (CNT) and two-dimensional layered materials (the transition metal dichalcogenide family of materials) as the atomically thin channel. We are also developing techniques to minimize the contact resistance and the parasitic capacitance. By building practical nanosystems of these emerging technologies, we learn how to solve fundamental device and materials science problems that have system-level impact.

I started doing research on memory devices around 2003. Research on memory had been rather “predictable” for many years until recently. It was predictable because the major advances for memory devices involved scaling down the physical dimensions of essentially the same device structure using basically the same materials. The situation has changed in the last two decades. Memory devices are beginning to be difficult to scale down. But perhaps the most important change is that new applications and products (e.g. mobile phones, tablets, enterprise-scale disk storage) in the last decade are often enabled by advances in memory technology, in particular solid-state non-volatile memories.
Our research on memory devices broadly covers phase change memory (PCM), metal oxide resistive switching memory (RRAM), ferroelectric memory and related topics such as selectors. We aim to understand the fundamental physics of these devices and develop models of how they work. We explore the use of various materials and device structures (e.g. 3D vertical RRAM) to achieve desired characteristics. We are working on building memory systems that are monolithically integrated in 3D with logic computing elements.

CellChips – Electronically programmable synthetic biology:
In-situ detection of chemical changes in human body at the cellular level can bring enormous benefits in diagnosis and in therapeutic monitoring. We are developing techniques to place micron-sized sensor chip inside each cell.
These CellChips will be equipped with molecular sensors and effectors that allow them to sense and trigger different cellular signaling or gene regulatory pathways. Using bi-directional radio communication with the sensor and effector functions, we will be able to change connections between cellular signaling pathways at will, in real time, without the need to generate new genetic constructs. This technology will provide to synthetic biology the same rapid prototyping and reconfigurability that was brought to electronics by field-programmable gate array (FPGA) technology deployed in data centers, and a variety of information and communication technologies that require reconfiguration post-deployment.
This may also open up an array of new biomedical
applications that range from novel medical diagnostic and therapeutic tools
that operate at single cell level to a novel class of autonomously operating
Nanofabrication and integrated electronics are the key enabling technologies of this research.
