With respect to power monitoring, experimental results with a 90-nm CMOS device show that it reduces power consumption by making it possible (1) to maintain a certain switching current ISW / leakage current ILEAK ratio in the active mode, and (2) to detect optimum body bias conditions (subthreshold current ISUBTH = substrate current ISUB) within an error of less than 20 % with respect to actual minimum leakage current values in the standby mode","PeriodicalId":447050,"journal":{"name":"2006 IEEE International Conference on IC Design and Technology","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125538334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To differ with the conventional FDSOI MOSFET, the proposed SOI structure shows enhanced performance by exploiting sidewall spacer process. For this new bFDSOI device, the electric field between the body and the source/drain (S/D) region is restrained by the block oxide resulting in that the ultra-short-channel effects (USCEs) are suppressed. Thus, the simulation results of bFDSOI exhibit reduced drain-induced barrier lowering (DIBL), excellent subthreshold swing (SS), good roll-off characteristics and high drain output resistance for 40 nm thick enough body. In order to eliminate the floating-body problem, the bFDSOI device must not be operated under the partially depleted (PD) regime. Although this is the limit of device design, as the gate length is scaled down, the requirement of the ultra-thin body (UTB) structure is not needed to maintain its ultra-short-channel characteristics control over the channel due to the block oxide serves as isolation between the body and the S/D region.

In this paper we address the prospects for nanoelectronics to exploit the tremendous possibilities of carbon nanotubes (CNTs). A brief introduction of the CNT basics and growth methods will be given. CNT applications as interconnects will be assessed. A comparison of state-of-the-art silicon MOSFETs with CNT-FETs highlights the significantly better performance of CNT devices.

However, in the past five years, planar double gate technology has been largely ignored, except for the case of IBM, because of the manufacturing challenges. These include the construction of the bottom gate underneath the FET body, the alignment of the bottom gate to the top gate, and the difficult task of incorporating metal gate or high k dielectric material for the bottom gate formation. From the design and device physics point of view, the planar double gate structure is predicted to behave similarly to single gate with the additional flexibility that the planar double-gate approach allows one to reach the limiting body thickness. In the past year, there has been significant renewed interest based on the increase in reports published by semiconductor companies, research labs and universities on the planar double gate manufacturing process.

The first phase is the modified power-force-directed scheduling (MPFDS) heuristic based on the well-known force-directed scheduling technique. The second phase is a post-processing procedure (power-area-saving) that is a revisit of the output schedule from the first phase in order to exploit the available rooms to get more power and/or the operating resources minimization.

The key or other sensitive information can be guessed by monitoring the execution time, the power variation and/or the electromagnetic radiation of the integrated circuit. This class of so-called side-channel attacks doesn't need expensive equipment or intrusive monitoring to be effective. We have shown that we can obtain the secret key out of a regular standard CMOS implementation of the AES encryption algorithm by monitoring the power consumption of only 2000 encryptions. This is orders of magnitude lower than the mathematical security of 2128 possible encryption keys to break the algorithm. The root cause of this problem is that standard CMOS is power efficient and it will only consume dynamic power when nodes are switching. Mathematical solutions have been proposed that include randomization and masking techniques. Our original approach is that we address the problem at circuit level. Instead of a full custom layout, a few key modifications are incorporated in a regular synchronous CMOS standard cell design flow. We present the basis for side-channel attack resistance and adjust the library databases and constraint files of the synthesis and place & route procedures.
