Predicting the Impact of Device Noise on Circuits and Systems
As semiconductors continue to deliver faster speeds at reduced operating voltages, random noise and jitter become ever more crucial aspects of circuit design. The ability to analyze and minimize the impact of device noise in critical analog/mixed-signal blocks is especially essential. In recent years, several new noise analysis approaches have been established beyond the traditional linear time-invariant (LTI) approaches of the past. These powerful noise analyses – based on nonlinear, time & frequency domain, transient & periodic methods – can achieve excellent accuracy in predicting noise performance, but they still have limited ranges of usefulness and applicability. This presentation shall attempt to navigate the landscape spanning from device noise generation and noise influences on critical circuit blocks, to important noise metrics and measurements and methods for their accurate prediction. Guidelines, tradeoffs, and best practices regarding the various noise analysis solutions available shall be explored with the goal of achieving the best possible predictions of the impact of random noise on various circuits and systems.

Nanomaterials for a New Era of Electronic Devices: Extending and Transforming the Trend
Silicon-based electronics remain the backbone of the ongoing digital revolution and continue to enhance computational ability, as well as the accessibility of data. As the range of possible applications for electronics grows, so does the realization that there are distinct limits to what silicon can do. Meanwhile, nanomaterials have been studied for decades for their attractive electronic properties coupled with mechanical flexibility, thermal resilience, and compatibility with solution-phase processing. From 1D carbon nanotubes (CNTs) to 2D graphene and transition metal dichalcogenides (TMDs), there is a growing list of nanomaterial options. Making use of the unique attributes offered by nanomaterials opens the way for new types of electronics that add value far beyond Moore’s law-related improvements, effectively transforming the traditional trend. In this talk, three distinct electronic applications employing nanomaterials will be discussed: 1) scalable low-voltage transistors, 2) printed electronic systems, and 3) ultrasensitive biological sensing. Each of these applications relies on capabilities that are unique to nanomaterials, which leads to performance, fabrication, and/or function that are not possible with traditional semiconductors. For instance, the low-cost printing of electronic sensors that must be mechanically flexible and able to operate within harsh environments, where silicon cannot survive. Additionally, low-voltage negative capacitance transistors with 2D TMD channels that can provide both voltage and size scalability in sub-10 nm technologies for future computing applications. Finally, fully printed biomedical immunoassays will be shown that offer a path for revolutionizing point-of-care diagnostic healthcare based on the extreme sensitivity of carbon nanotubes. As the coverage of this talk will be relatively broad in terms of applications, the primary takeaway will be an overview of a new era of electronics that is uniquely possible using nanomaterials. For decades, Si-based electronics have established a trend for devices and applications; nanomaterials hold the promise of extended and/or transforming that trend in the years to come.

EUV Lithography’s Path to Manufacturing: Challenges and Opportunities
After almost 30 years of development, Extreme Ultraviolet (EUV) lithography is finally moving into production, with several chip manufacturers announcing plans to begin EUV production in late 2018 or 2019. This tutorial session will give a brief background on EUV technology, explain key industry challenges, and discuss how EUV fits into memory manufacturing. The 13.5 nm wavelength of EUV light can print complex patterns with features below 20 nm, which allows one EUV pattern to replace several 193nm immersion patterning steps. The EUV light source is complex, and EUV introduction has been delayed by low light intensity and system reliability. ASML is delivering systems which meet source power requirements, but system availability is still not meeting manufacturing requirements. Stochastic, or random, effects drive local CD variation and may cause missing or bridged patterns at smaller dimensions. Reticle defects are another industry concern; the multilayer mirror makes it difficult to create a defect-free reticle, and the lack of a mature pellicle process increases the risk of particles falling onto the reticle. The industry has focused on EUV applications for logic chips, but DRAM also has several applications where EUV offers benefits over 193nm immersion lithography. This talk will explain the concepts behind the jargon, and give some context for how EUV will affect the industry.
Scott Light received a BS degree in Chemical Engineering from Rice University (Houston, Tx) in 1997. He joined Micron in 1997, and has worked in numerous roles in the R&D Photolithography team. He spent 2 years at IMEC in Belgium as Micron’s assignee to the 157nm lithography program. He is currently leading the TD Photo Imaging Science team, working on new photo materials, EUV implementation, and DRAM roadmaps. Mr. Light has co-authored approximately 10 conference papers and has over 25 patents.

Considerations and implementations for high data rate serial link design
Wireline transceivers are responsible for sending and receiving data from one chip to and from another. The key specifications for such designs might include data rate, power consumption, area, and connection distance. The distance and data rate specifications, in particular, drive the choice of physical channel to be used for the connection, which in turn will drive requirements such as the equalization capabilities of the transceiver. For short chip-to-chip channels with limited frequency-dependent loss, simple transceivers with little or no integrated equalization are appropriate. For longer channels crossing backplanes and involving multiple transitions through connectors, complex transceivers with adaptive transmit and receive equalization are the right choice. As connection distances grow even longer , optical interconnect becomes an attractive option. In this talk, a framework for understanding serial link design will be presented, including a discussion of basic equalization strategies and key challenges. Next, several design examples will be presented, covering approaches to key classes of interconnect, from short reach channels to backplane channels to enabling highly integrated optical approaches. The talk will conclude with a discussion of emerging directions in this field.

Planar CMOS Devices for Ultra-Low Power Applications at Nanometer Nodes
In this presentation, planar CMOS device structures for low-power applications at nanometer nodes are discussed. It is well-known that he continuous scaling of MOSFETs towards their ultimate dimension near 5-nm regime has become more challenging due to their fundamental constraints such as short-channel effects (SCEs) and process-variability. The SCEs degrade the performance of scaled devices with higher sub-threshold swing and leakage current that pose a sever challenge to control device performance by gate bias. On the other hand, the process variability severely impacts the delay and power variability in VLSI devices, circuits, and systems. The impact of the increasing amount of within-die process variability on the yield of VLSI circuits, such as SRAM, has imposed an enormous challenge to design advanced System-on-Chips using bulk-CMOS technology. In order to mitigate the risk of process variability, new statistical design methodologies have evolved. Though, these statistical modeling techniques allow designers best possible solution to optimize the impact of variability, however, process variability constraint limits the circuit performance and yield. Therefore, to mitigate the risk of process variability, variability-tolerant device architectures are required. In this talk, the architecture and modeling of a novel variability-tolerant buried-halo MOSFET device structure is presented for low-power CMOS technology at nanometer nodes.

Physical Characterization of Advanced Device Materials
A variety of materials are now under investigation for advanced device concepts and applications. In addition to establishing materials properties in the context of device physics and potential performance, an understanding of the integration constraints and the impact on the materials interfaces must also be addressed, as interfaces with contacts and dielectrics dominate device characteristics. This tutorial will focus on the physical characterization aspects of such advanced device materials, such as high-mobility and 2D materials, complex oxides, and nitrides, as well as the role of impurities and defects in these materials. Topics in advanced device materials development and metrology to be covered include:
Detection limits of characterization techniques
In-situ vs. ex-situ characterization
Surface and interface analysis methods
Electron and ion mass spectrometry methods
The physics of the characterization/metrology techniques will be discussed, and examples of correlating such physical and chemical materials characterization to device behavior will also be presented.
