This file contains excerpts from the most modern Textbook on “Characterization.” It was printed in 1998 by John Wiley and Sons. The Preface to its 1 st Edition helps explain what “Characterization” means to the Semiconductor industry. Excerpts from Chapter 1 quote work done by my earliest Industry team (the Dave Perloff Gang) and contains references showing me as co-author. Fred E Wahl Thanks to Dieter Schroder.
