Advanced nanometer technologies have led to a drastic increase in operational frequencies resulting in the performance of circuits becoming increasingly vulnerable to timing variations. The increasing process spread in advanced nanometer nodes poses considerable challenges in predicting post-fabrication silicon performance from timing models. Thus, there is a great need to qualify basic building structures on silicon in terms of critical parameters before they could be integrated within a complex System-on-Chip (SoC). The work of this paper presents a configurable circuit and an associated power-aware at-speed test methodology for the purpose of qualifying basic standard cells and complex IP structures to detect the presence of timing faults. Our design has been embedded within test-chips used for the development of the 28 nm Fully Depleted Silicon On Insulator (FD-SOI) technology node. The relevant silicon results and analysis validate the proposed power-aware test methodology for qualification and characterization of IPs and provide deeper insights for process improvements. 相似文献

In this paper, we present an exhaustive study on the influence of resistive-open defects in pre-charge circuits of SRAM memories.
In SRAM memories, the pre-charge circuits operate the pre-charge and equalization at a certain voltage level, in general Vdd,
of all the couples of bit lines of the memory array. This action is essential in order to ensure correct read operations.
We have analyzed the impact of resistive-opens placed in different locations of these circuits. Each defect studied in this
paper disturbs the pre-charge circuit in a different way and for different resistive ranges, but the produced effect on the
normal memory action is always the perturbation of the read operations. This faulty behavior can be modeled by Un-Restored
Write Faults (URWFs) and Un-Restored Read Faults (URRFs), because there is an incorrect pre-charge/equalization of the bit
lines after a write or read operation that disturbs the following read operation. In the last part of the paper, we demonstrate
that the test of URWFs is more effective in terms of resistive defect detection than that of URRFs and we list the necessary
test conditions to detect them.

The development of a novel, chemoselective, and catalytic deprotection methodology that proceeds under mild and neutral conditions is described, and its mechanism of action is analyzed in some detail. The scope, limitations, and advantages of this protocol are discussed. Selected applications in synthesis are also highlighted. 相似文献

The influence of the temperature on the protonation of acetonitrile by acidic zeolites was studied by infrared spectroscopy.
Acidity at room or low temperature was not correlated with the protonation temperature, but the zeolitic structure played
an important role. A new technique is presented for the study of the acidity of solids under reaction conditions. A good correlation
was obtained in a series of various zeolites between the catalytic activity in the cracking of n-hexane and the protonation temperature of acetonitrile.

Static light scattering (SLS) was applied to monitor the rehydration process of milk protein concentrate (MPC) powder. The size distribution and volume concentration of the suspended powder particles were measured to quantify the dissolution kinetics of MPC powder. The results obtained showed that the low solubility index reported for MPC85 (85% protein) powder at room temperature was the consequence of slow dissolution kinetics rather than the presence of a large amount of insoluble material in the rehydrated powder. The rehydration process of MPC85 powder occurs in two overlapping steps: the disruption of agglomerated particles into primary powder particles and, simultaneously, the release of material from the powder particles into the surrounding aqueous phase. The latter process appeared to be the rate-limiting step of dissolution of MPC85 and was accelerated by an increase of the solvent temperature. 相似文献

Specular ellipsometry is a well-known and efficient technique to characterize surfaces and coatings. This technique has been extended to the measurement of scattered light. We present an experimental setup, using a polarization modulator, which permits us to characterize transition layers and roughness without a calibration procedure. Experimental results are presented concerning transition layers for damage threshold applications and for rough surfaces or bulks. 相似文献

Electrostatic interactions dominate the diffusion of proteins in a nanochannel, which was measured and modeled for pH values above and below the isoelectric points of three lectin proteins. Maximal diffusion coefficients were obtained when the proteins were neutral at their pI. This pH-controlled transport led to a separation of biomolecules across the nanochannel. A pI shift was observed, due to reversible adsorption of proteins on the walls, which affects the pH in the nanochannel. 相似文献

High-mobility III-V heterostructures are emerging and very promising materials likely to fulfil high-speed and low-power specifications for ambient intelligent applications. The main objective of this work is to theoretically explore the potentialities of MOSFET based on III-V materials with low bandgap and high electron mobility. First, the charge control is studied in III-V MOS structures using a Schr?dinger-Poisson solver. Electronic transport in III-V devices is then analyzed using a particle Monte Carlo device simulator. The external access resistances used in the calculations are carefully calibrated on experimental results. The performance of different structures of nanoscale MOS transistor based on III-V materials is evaluated and the quasi-ballistic character of electron transport is compared to that in Si transistors of same gate length. 相似文献
