The characterization of the electromagnetic compatibility (EMC) performance of integrated circuits (ICs) is receiving increasing focus as new applications and technology trends combine to raise the complexity of EMC compliance. The increased focus is driving the need for standardized measurement procedures to enable consistent evaluation and comparison of different devices. This paper discusses the need for standardization, describes the work in process by IEC TC47/SC47A Working Group 9 to standardize emissions and immunity EMC test methods for ICs, and examines trends in IC EMC. 相似文献

This paper presents a comparative study of susceptibility reduction techniques for electromagnetic interference (EMI) in digital integrated circuits (ICs). Both direct power injection (DPI) and very-fast transmission-line pulsing (VF-TLP) methods are used to inject interference into the substrate of a single test chip. This IC is built around six functionally identical cores, differing only by their EMI protection strategies (RC protection, isolated substrate, meshed power supply network) which were initially designed for low emission design rules. The ranking of three of these cores in terms of electromagnetic immunity is then compared with the one of their radiated emission, thanks to near-field scanning (NFS) measurements. This leads to the establishing of design guidelines for low EMI in digital ICs. 相似文献

This paper is focused on the electromagnetic compatibility (EMC) of integrated circuits. The introduction gives general keyword definitions and principles for emission and susceptibility. The second part deals with the evolution of integrated circuit design and technology with its consequences on EMC. The third part describes the mechanisms for generating parasitic noise within integrated circuits and the role of the package and on-chip supply network. Next, the standardized measurement methods are described for both parasitic emission characterization (conducted and radiated) and immunity from 1 MHz to 1 GHz. Issues and proposals up to 18 GHz are discussed. The advances in modeling of emission are also addressed, as well as the issues in immunity prediction. 相似文献

This paper presents a comprehensive modelling methodology for the electromagnetic immunity of integrated circuits (ICs) to direct power injection (DPI). The aim of this study is to predict the susceptibility of ICs by the means of simulations performed on an appropriate electrical model of different integrated logic cores located in the same die. These cores are identical from a functional point of view, but differ by their design strategies. The simulation model includes the whole measurement setup as well as the integrated circuit under test, its environment (PCB, power supply) and the substrate model of each logic core. Simulation results and comparisons with measurement results demonstrate the validity of the suggested model. Moreover, they highlight the interest of the aforementioned protection strategies against electromagnetic disturbances. 相似文献

This paper presents the results obtained with a specific test mask designed at Motorola for the study of the electromagnetic parasitic emissions in integrated circuits (IC). First, origins of parasitic emissions are presented for CMOS circuits, and electromagnetic compatibility (EMC) measurements of IC emissions are detailed: a radiated measurement method with respect to the IEC61967-2 standard and a conducted one with respect to the IEC61967-4 standard. The REGINA test chip is then described, with a focus on particular structures allowing to test and verify some design guidelines for EMC, like delay cell, emissive structure or on-chip sensor. The printed circuit board that is use to implement the test chip and the experiment test bench are also described. A set of measurements is presented and some guidelines are deduced and recommended as design rules. 相似文献

Ground bounce as a result of fast switching currents is on of the main source for the electromagnetic emission of an integrated circuit. One common method to reduce the ground bounce amplitude is the use of on-chip decoupling capacitors. Besides of this measure other concepts, like the use of different power supply pins, are supposed to reduce ground bounce too. But for all of these measures detail knowledge for the optimal use does not exists so far. In this paper we present a test chip as well as a measurement method for investigations on these measures towards future design guidelines. 相似文献

Like many of the technologies used to process integrated circuits, the road to manufacturing for rapid thermal processing
(RTP) has been twisted. What began as a speculative laboratory apparatus has evolved into a cornerstone of IC technology.
Qualities that make RTP desirable for IC manufacture include the ability to process wafers individually, the ability to minimize
the time wafers spend at elevated temperature, the convenience of clustering RTP to other systems, and the possibility of
maintaining cold reactor walls. This paper will review how these properties make RTP desirable. The paper also will present
an overview of the difficulties surrounding the use of RTP and describe how many serious hurdles have been overcome. It will
summarize the evolution of RTP from a curiosity to a mainstay technology in building integrated circuits. It then will describe
SEMATECH’s role in working with RTP, ending with a direction for future application of RTP based on the National Technology
Roadmap for Semiconductors (NTRS). 相似文献
