This report presents details of the eighth six-inch baseline run, CMOS200, where a moderately complex 0.35 μm twin-well, silicided, LOCOS process was implemented. This process was based on the previous 0.35 μm six-inch run, CMOS192. CMOS200 was the start-up run in the new Marvell NanoLab, showing the ability to fabricate operational MOSFETs, after the move from the Microlab.

We consider the problem of estimating the locations of a set of points in a k-dimensional euclidean space given a subset of the pairwise distance measurements between the points. We define a notion of non-contractibility and show that the relaxation gives the exact point locations when the underlying graph is non-contractible. The performance of the algorithm is evaluated on an experimental data set obtained from a network of 44 nodes in an indoor environment and is shown to be robust to non-line-of-sight errors.

Scaling of CMOS technology into the deep submicron regime gives rise to process variability, which in turn compromises circuit yield. One of the main sources of variability is random dopant fluctuation (RDF) in the channel. Fully Depleted Silicon on Insulator technology has been proposedas a promising alternative to bulk CMOS, due to it’s undoped channel which reduces RDF, as well as due to its better electrostatic control of the channel.

Photonic innovation is becoming ever more important in the modern world. Optical systems are dominating shorter and shorter communications distances, LED's are rapidly emerging for a variety of applications, and solar cells show potential to be a mainstream technology in the energy space. The need for novel, energy-efficient photonic and optoelectronic devices will only increase. This work unites fundamental physics and a novel computational inversedesign approach towards such innovation.

We propose a novel and inexpensive infrastructure for precise localization in non-line-of-sight wireless environments using RFID tags. The proposed system utilizes specialized tags that we term as supertags. Each supertag is an array of individual single antenna RFID tags closely spaced so as to emulate a “virtual” antenna array. Multiple such supertags are installed in a 3D environment where we are interested in localizing mobile agents equipped with an RFID reader.

Cake is a coordinated, multi-resource scheduler for shared distributed storage environments with the goal of achieving both high throughput and bounded latency. Cake uses a two-level scheduling scheme to enforce high-level service-level objectives (SLOs). First-level schedulers control consumption of resources such as disk and CPU. These schedulers (1) provide mechanisms for differentiated scheduling, (2) split large requests into smaller chunks, and (3) limit the number of outstanding device requests, which together allow for effective control over multi-resource consumption within the storage system. Cake’s second-level scheduler coordinates the first-level schedulers to map high-level SLO requirements into actual scheduling parameters. These parameters are dynamically adjusted over time to enforce high-level performance specifications for changing workloads. We evaluate Cake using multiple workloads derived from real-world traces. Our results show that Cake allows application programmers to explore the latency vs. throughput trade-off by setting different high-level performance requirements on their workloads. Furthermore, we show that using Cake has concrete economic and business advantages, reducing provisioning costs by up to 50% for a consolidated workload and reducing the completion time of an analytics cycle by up to 40%.

The constant pace of CMOS technology scaling has enabled continuous improvement in integrated-circuit cost and functionality, generating a new paradigm shift towards mobile computing. However, as the MOSFET dimensions are scaled below 30nm, electrostatic integrity and device variability become harder to control, degrading circuit performance. In order to overcome these issues, device engineers have started transitioning from the conventional planar bulk MOSFET toward revolutionary thin-body transistor structures such as the FinFET or fully-depleted silicon-on-insulator (FDSOI) MOSFET. While these alternatives appear to be elegant solutions, they require increased process complexity and/or more expensive starting substrates, making development and manufacturing costs a concern. For certain applications (such as mobile electronics), cost is still an important factor, inhibiting the quick adoption of the FinFET and FDSOI MOSFET structures while providing an opportunity to extend the competitiveness of planar bulk-silicon CMOS. A segmented-channel MOSFET (SegFET) design, which combines the benefits of both planar bulk MOSFETs (i.e. lower process complexity and/or cost) and thin-body transistor structures (i.e. improved electrostatic integrity), can provide an evolutionary pathway to enable the continued scaling of planar bulk technology below 20nm. In this work, experimental results comparing SegFETs and planar MOSFETs show suppressed short-channel effects and comparable on-state current (despite halving the effective device width).

Shark is a new data analysis system that marries query processing with complex analytics on large clusters. It leverages a novel distributed memory abstraction to provide a unified engine that can run SQL queries and sophisticated analytics functions (e.g., iterative machine learning) at scale, and efficiently recovers from failures mid-query. This allows Shark to run SQL queries up to 100× faster than Apache Hive, and machine learning programs up to 100× faster than Hadoop. Unlike previous systems, Shark shows that it is possible to achieve these speedups while retaining a MapReduce-like execution engine, and the fine-grained fault tolerance properties that such engines provide. It extends such an engine in several ways, including column-oriented in-memory storage and dynamic mid-query replanning, to effectively execute SQL. The result is a system that matches the speedups reported for MPP analytic databases over MapReduce, while offering fault tolerance properties and complex analytics capabilities that they lack.

An increasing number of consumer products include user interfaces that rely on touch input. While digital fabrication techniques such as 3D printing make it easier to prototype the shape of custom devices, adding interactivity to such prototypes remains a challenge for most designers. We introduce Midas, a software and hardware toolkit to support the design, fabrication, and programming of flexible capacitive touch sensors for interactive objects. With Midas, designers first define the desired shape, layout, and type of touch sensitive areas in a sensor editor interface. From this high-level specification, Midas automatically generates layout files with appropriate sensor pads and routed connections. These files are then used to fabricate sensors using digital fabrication processes, e.g. vinyl cutters and circuit board printers. Using step-by-step assembly instructions generated by Midas, designers connect these sensors to our microcontroller setup, which detects touch events. Once the prototype is assembled, designers can define interactivity  for their sensors: Midas supports both record-and-replay actions for controlling existing local applications and WebSocket-based event output for controlling novel or remote applications. In a first-use study with three participants, users successfully prototyped media players. We also demonstrate how Midas can be used to create a number of touch-sensitive interfaces.
