A fabrication process has been developed for fully planarized Nb-based superconducting inter-layer connections (vias) with minimum size down to 250 nm for superconductor very large scale integrated (VLSI) circuits with 8 and 10 superconducting layers on 200-mm wafers. Instead of single Nb wiring layers, it utilizes Nb/Al/Nb trilayers for each wiring layer to form Nb pillars (studs) providing ve...

Deep neural networks have shown excellent performance for stereo matching. Many efforts focus on the feature extraction and similarity measurement of the matching cost computation step while less attention is paid on cost aggregation which is crucial for stereo matching. In this paper, we present a learning-based cost aggregation method for stereo matching by a novel sub-architecture in the end...

We present a novel methodology for characterization of sub-quartermicron CMOS technologies. It involves process calibration, device calibration employing two-dimensional device simulation and automated Technology Computer Aided Design (TCAD) optimization and, finally, transient mixed-mode device/circuit simulation. The proposed methodology was tested on 0.25 m technology and applied to 0.13 m t...

NASA/PL has been developing technologies for a novel and unified approach to point a laser beam from deep space with sub-micro-radian precision for optical communication systems. The approach is based on using high bandwidth inertial sensors to compensate for jitter excursions caused by spacecraft vibrations. This novel use of high bandwidth inertial sensors enables the implementation of laser ...

Spatial mapping of optical force near the hot-spot of a metal-dielectric-metal bow-tie nanoantenna at a wavelength of 1550 nm is presented. Non contact mode atomic force microscopy is used with a lock-in method to produce the map. Maxwell’s stress tensor method has also been used to simulate the force produced by the bow-tie and it agrees with the experimental data. If dual lock-in amplifiers a...

Recent rapid progress of information technology owes very much to that of semiconductor technologies, especially to that of CMOS. However, the downsizing of CMOS devices is now facing severe difficulties for sub-0.1 μm generations because of various expected limitations. For, example, SiO2 has been used almost exclusively as the material for the gate insulator since the first realization of the...

In order to understand the influence of magnetic fields on the propagation properties of waves, as derived from different local helioseismology techniques, forward modeling of waves is required. Such calculations need a model in magnetohydrostatic equilibrium as initial atmosphere to propagate oscillations through it. We provide a method to construct such a model in equilibrium for a wide range...

This paper presents a comprehensive analysis of the themal effects in advanced high performance interconnect systems arising due to selfheating under various circuit conditions, including electrostatic discharge. Technology (Cu, low-k etc) and scaling effects on the thermal characteristics of the interconnects, and on their electromigration reliability has been analyzed simultaneously, which wi...

Current-based tests are the most effective methods available to detect resistive shorts. Delta IDDQ testing is the most sensitive variant and can handle off-state currents of 10-100 mA of a single core. Nevertheless this is not sufficient to handle the next generations of very deep sub-micron technologies. Moreover delay-fault testing and very-low voltage testing are not a real alternative for ...
