2 Motivation Physical limitations of silicon-based devices inhibit continued innovation in IT, communications, and electronics. Conventional micro-fabrication techniques are reaching the limits of their capabilities, while fabrication costs and complexity continue to grow. Breakthroughs for building electronics at the nanoscale requires new materials and new manufacturing concepts. Achieving semiconducting behavior through nanoparticles eliminates the need high quality Si substrates avoids energy intensive fabrication of high purity silicon wafers. allows for inexpensive, lightweight flexible substrates compatible with roll-toroll processing. SRC/SEMATECH Engineering Research Center for Environmentally Benign Semiconductor Manufacturing 2
3 Quantum Dots (QDs) Nanocrystals of a semiconductor compound Quantum dot size is not limited by lithography Diameters in the 1 to 10 nm length scale Electrons are quantum confined in 3D Enable new devices and markets such as quantum information processing: spin-transistors, nanomagnets quantum computing electron spin-based memory. The Quantum Dot SRC/SEMATECH Engineering Research Center for Environmentally Benign Semiconductor Manufacturing 3
4 QDs in future electronics Linear and nonlinear quantum transport phenomena Transitions among quantum confined states Control over the behavior of a single or a few electrons as well as that of a single or a few photons Switching device structure with the potential for much higher speeds, lower power consumption and higher packing densities than CMS transistors (Alignment of Epitaxial Quantum Dots: Springer, 2007) resonant tunneling transistors (RTDs single-electron transistors (SETs) spin transistors Next generation memory devices (M. Geller et. At: Appl. Phys. Lett. 92, , 2008) storing one terabyte (1000 gigabytes) of data per square inch write information to this memory in just 6 nanoseconds SRC/SEMATECH Engineering Research Center for Environmentally Benign Semiconductor Manufacturing 4
5 QDs ptoelectronics Frequency of light emission depends on QD size Narrow emission band High quantum yields: 85 % Broad excitation spectra Chemical/photo stability Applications tunable IR-UV lasers and LEDs display luminophores optical electro-modulation, optical limiting DNA site markers efficient sensors of explosives and toxic materials.

6 Detecting a single photon Detectors with the capability to directly measure the photon number of a pulse of light enable linear optics quantum computing, affect the security of quantum communications, and can be used to characterize, and herald non-classical states of light. E. J. Gansen et. al, Nature Photonics 1, (2007) SRC/SEMATECH Engineering Research Center for Environmentally Benign Semiconductor Manufacturing 6
7 ESH Nanoparticles which are not confined to a surface film are free to transport by diffusion and convection. The size (typically <10 nm) limits the ability to be filtered or separated efficiently with current technology. Early consideration the ESH life cycle in the design and development of a new material reduces the total cost of introducing and using a technology compared to revisions made closer to high volume manufacturing. Developing technology separately from ESH impact and evaluating ESH impact without the capability to affect a technology is inefficient since the two are intimately connected. SRC/SEMATECH Engineering Research Center for Environmentally Benign Semiconductor Manufacturing 7
8 Scope Processes for tethering QDs to surfaces with precise spatial control is required in order to exploit the novel electronic properties of these nanoparticles ESH benign fabrication methods are desired which are compatible with wafer processing and also with flexible substrates. The use of flexible substrates is required for roll-to-roll processing, which is a high-volume, low-cost manufacturing method.
