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....

Facility Fluids Metrics and Test Methods

Aug 05, 1999 | Deborah Franke

This technology transfer was prepared by the Research Triangle Institute (RTI) as part of SEMATECH's Facility Fluids Project (S100). It is a compilation of information on existing facility fluids metric and test methods. Information on standard methods was gathered from SEMATECH and SEMI. Other information was obtained from a literature search of journals and conference proceedings. The published information primarily is concerned with the test equipment used and what levels of detection and purity were found. Many of the articles discussed the use of new equipment, either commercial or experimental. Extensive annotated bibliographies are append to the report....

Silicon Test Wafer Specification for 180 nm Technology

Aug 05, 1999 | Goodall, Randy

In 1998, the International 300 mm Initiative (I300I) demonstration and characterization programs will focus on 180 nm technology capability. To support these activities, I300I and equipment supplier demonstration partners must use starting silicon wafers with key parameters specified at a level appropriate level for 180 nm processing, including contamination and lithographic patterning. This document describes I300I's silicon wafer specifications, as developed with the I300I Silicon Working Group (member company technical advisors) and SEMI Standards....

Test Structures for Benchmarking the Electrostatic Discharge (ESD) Robustness of CMOS Technologies

Aug 05, 1999 | Alexander, Robert

This document defines a set of standard test structures with which to benchmark the electrostatic discharge (ESD) robustness of CMOS technologies. The test structures are intended to be used to evaluate the elements of an integrated circuit in the high current and voltage ranges characteristic of ESD events. Test structures are given for resistors, diodes, MOS devices, interconnects, silicon control rectifiers, and parasitic devices. The document explains the implementation strategy and the method of tabulating ESD robustness for various technologies....
