Parasitic Extraction for Deep Submicron and Ultra-deep Submicron Designs

Aug 09, 1999 | Cadence Design Systems, Inc.

Shrinking process technologies and increasing design sizes continually challenge design methodologies and EDA tools to develop at an ever-increasing rate. Before the complexities of deep submicron (DSM), gate and transistor delays dominated interconnect delays, and enabled simplified design methodologies that could focus on device analysis. The advent of DSM processes is changing all of this, invalidating assumptions and approximations that existing design methodologies are based upon, and forcing design teams to re-tool. High-capacity parasitic extraction tools are now critical for successful design tape-outs....

Alternatives to HASL: Users Guide for Surface Finishes

Aug 09, 1999 | Dan T. Parquet and David W. Boggs, Merix

A great deal of controversy continues to surround the use of Hot Air Solder Leveling (HASL) in the production of printed circuit boards (PCBs). The financial burden, technological limitations and environmental issues surrounding the HASL process continue to grow. This requires an in-depth review by the printed circuit board manufacturing plant, as well as the assembly operation and instrument designers ( OEMs), to determine what alternative surface finishes are appropriate....

Introducing the OSP Process as an Alternative to HASL

Aug 09, 1999 | David W. Boggs, Senior Process Engineer, Merix Corporation - Viasystem

Organic Solderability Preservatives (OSPs), also known as anti-tarnish, on bare copper printed circuit boards (PCBs) are becoming more prevalent in the electronics industry as the low-cost replacement to Hot Air Solder Leveling (HASL). Introducing the anti-tarnish alternative into the customer sites requires working closely with the coating supplier, assembler, and Original Equipment Manufacturer (OEM) to gain a mutual understanding of respective processing concerns and finished product requirements....

Effects of Tg and CTE on Semiconductor Encapsulants

Jul 21, 1999 | Dr. Mark M. Konarski

As the role of direct-chip-attachment increases in the electronics industry, the reliability and performance of COB packaging materials becomes an increasing concern. Although many factors influence component reliability, the biggest determinants of performance are often the glass transition temperature (Tg) and the coefficient of thermal expansion (CTE) of the encapsulant or underfill. This paper discusses exactly what these properties are, how they are measured, and why they are important to device-reliability....

Computer Vision Face Tracking For Use in a Perceptual User Interface

May 07, 1999 | Gary R. Bradski; Microcomputer Research Lab

As a first step towards a perceptual user interface, a computer vision color tracking algorithm is developed and applied towards tracking human faces. Computer vision algorithms that are intended to form part of a perceptual user interface must be fast and efficient. They must be able to track in real time yet not absorb a major share of computational resources: other tasks must be able to run while the visual interface is being used. The new algorithm developed here is based on a robust nonparametric technique for climbing density gradients to find the mode (peak) of probability distributions called the mean shift algorithm....

An Overview of Advanced Failure Analysis Techniques for Pentium® and Pentium® Pro Microprocessors

May 07, 1999 | Yeoh Eng Hong, Lim Seong Leong, Wong Yik Choong, Lock Choon Hou, Mahmud Adnan; Intel Penang Microprocessor Failure Analysis Department, Malaysia

Failure analysis (FA) is one of the key competencies in Intel. It enables very rapid achievement of world class manufacturing standards, resulting in excellent microprocessor time-to-market performance. This paper discusses the evolution of FA techniques from one generation of microprocessors to another....
