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....

Overview of Quality and Reliability Issues in the National Technology Roadmap for Semiconductors

Aug 05, 1999 | Barpoulis, Dino

This document is an update to the 1994 Quality and Reliability Roadmap issued in support of the 1994 National Technology Roadmap for Semiconductors. This report revisits the challenges, constraints, priorities, and research needs pertaining to quality and reliability issues. It also provides key project proposals that must be implemented to address concerns about reliability attainment and defect learning. An expanded section on test-to-test, diagnostics, and failure analysis; an edited version of the Product Analysis Forum Roadmap; and an appendix containing a draft report highlighting reliability issues is included....

Evaluating Automated Wafer Measurement Instruments

Aug 05, 1999 | Steven A. Eastman

This document demonstrates a sequential process of evaluating automated wafer instruments and discusses why this approach is useful for studying instruments that have automation features such as loading and focusing mechanisms. The methodology specifies a series of experiments consisting of two or more capability studies followed by a stability study. Each experiment achieves a separate goal, yet combines with the others in providing information needed to assess the usefulness of the instrument....

Properties and Performance Of Hybrid Aluminium Electrolytic / Electrochemical Capacitors

Aug 05, 1999 | John R. Miller, JME, Inc. & David A. Evans, Evans Company

Test data was recently presented for a hybrid electrolytic/ electrochemical capacitor having sintered tantalum anodes and RuO2 cathodes. A 50-V, 18-mF capacitor of this design had electrical performance that was comparable to an advanced aluminum electrolytic capacitor but with only one-tenth the volume and just one-half the mass...
