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 1st 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.
