Lecture 9: More About Wires and Wire Models
Lecture 9: More about wires and wire models Computer Systems Laboratory Stanford University [email protected] Copyright © 2007 Ron Ho, Mark Horowitz R Ho EE371 Lecture 9 Spring 2006-2007 1 Introduction • Readings • Today’s topics – Wires become more important with scaling • Smaller features mean faster devices but not faster wires. – Different kinds of wires have different scaled performance • Wires that scale in length • Wires that are fixed-length – How to deal with and estimate wire performance R Ho EE371 Lecture 9 Spring 2006-2007 2 A modern technology is mostly wires • Cross-section, Intel’s 65nm tech – 8 metal layers – Low-κr dielectrics (κr = 2.7) – Wires are 2x taller than wide • Wires are here • Transistors are here P. Bai, et al., “A 65nm logic technology featuring 35nm gate lengths, enhanced channel strain, 8 Cu interconnect…,” IEDM 2004. R Ho EE371 Lecture 9 Spring 2006-2007 3 Resistance, revisited… Resistance is resistivity/area, but… • Copper needs a diffusion barrier that reduces its cross-section – Also, barrier may not be evenly deposited • Copper can be overpolished – Can cause dishing (less thick) • Electrons can scatter off the edges – Happens more for thinner wires – Increases the base resistivity t w P. Kapur, “Technology and reliability constrained future copper interconnects: Resistance modeling,” IEEE Trans. Electron Devices, April 2002. R Ho EE371 Lecture 9 Spring 2006-2007 4 Capacitance, revisited… Model capacitance by four plates, each κ(A/d) • Plus a near-constant fringe term 0.1fF/um (fringe scales slowly) • Relative dielectrics differ, with low-κ within a layer – SiOF (3.5) or SiOC (2.5) – Reduces (dominant) sidewall cap – Wires are taller than they are wide κr2 •No low-κ between wire layers κr1 κr1 – For material strength κr2 s ILD A “sandwich” model R. -

All rights reserved. ABS Plaza 16855 Northchase Drive Houston, TX 77060 USA Foreword Foreword These Guidance Notes provide ABS recommendations for the design and construction of cable trays and junction boxes. These Guidance Notes are applicable to fixed and floating offshore structures as well as drilling units. These Guidance Notes provide recommendations and best practices for standard specifications of certain electrical and instrumentation components thus improving cost efficiency (i.e., design man-hours, operation and maintenance costs), and increasing predictability of operation without compromising quality and safety in offshore structures and units. The recommendations in these Guidance Notes are based on industrial experiences, project experience, shipyard practices, manufacturer’s data sheets, national regulations, international standards, and ABS Rules. These Guidance Notes become effective on the first day of the month of publication. Users are advised to check periodically on the ABS website www.eagle.org to verify that this version of these Guidance Notes is the most current. We welcome your feedback.

Chapter 9 Chip Bonding At
9 CHIP BONDING AT THE FIRST LEVEL The I/O interface to the die primarily interconnects electrical power, ground and signals. It must provide for low impedance for the power distribution system, so as to keep switching noise within specification, and controlled impedance for the signal leads to allow adequate signal integrity. In addition it must accommodate all the I/O and power and ground leads required, and at the same time, minimize the cost for high volume assembly. The secondary role of chip bonding is to be mechanically robust, not interfere with thermal man- agement and be the geometrical transformer from the die features to the next level of packaging features. There are many options for the next level of interconnect, including: ¥ leadframe in a single chip package ¥ ceramic substrate in a single chip package ¥ laminate substrate in a single chip package ¥ ceramic substrate in a multichip module ¥ laminate substrate in a multichip module ¥ glass substrate, such as an LCD (liquid crystal display) ¥ laminate substrate, such as a circuit board ¥ ceramic substrate, such as a circuit board For all of these first level interfaces, the chip bonding options are the same. Illustrated in Figure 9-1, they are: ¥ wirebond ¥ TAB (tape automated bonding) ¥ flip chip; either with a solder interface, a polymer adhesive or a welded joint Because of the parallel efforts in widely separated applications involving similar, but slightly dif- ferent variations of chip attach techniques, seemingly confusing names have historically evolved to describe some of the attach technologies. COG (chip on glass) refers to assembly of bare die onto LCD panels. -

Industrial MI Wiring Cable
Industrial MI Wiring Cable Installation Manual for Alloy 825 Sheath Cable Wiring Systems Important Safeguards and Warnings WARNING: FIRE AND SHOCK HAZARD. nVent PYROTENAX mineral insulated (MI) industrial wiring cables must be installed in accordance with the requirements of national and local codes and standards, the installation instructions in this manual, and the customer’s specification. Read these important safeguards and carefully follow the installation instructions. • Ensure the cable has been stored properly and is in good condition prior to commencing installation. • Always use safe working practices when installing cables, observing OSHA and other national safety rules. • Store cables indoors in a clean, dry, covered area, if possible. • During the time that the cables are exposed and during cable pulling activities, protect cables from nearby or overhead work to prevent damage to the cable sheath. • Do not pull cables around corners that have sharp edges, such as corners in cable trays, or other obstructions. • Prevent damage to cables by removing any abrasions or sharp edges from surface of support system. • Damage to cables or components can cause sustained electrical arcing or fire. Do not energize cables that have been damaged. Damaged cable or terminations may need to be repaired or replaced. Damaged cable should be repaired by a qualified person. • When installing cables which may be exposed to hydrocarbon flash fires, use only steel or stainless steel in the support system. ii | nVent.com Table of Contents General Information -
