DICTIONARY OF TERMS FOR SOLID-STATE TECHNOLOGY, 7th Edition |
JESD88F | Feb 2018 |
This reference for technical writers and educators, manufacturers, and buyers and users of discrete solid state devices is now available. It should aid the technical committees of JEDEC in the avoidance of multiple definitions and reduce the proliferation of redundant definitions. The long-term goal is to include definitions from all JEDEC publications and standards. Each of the approximately two thousand entries is referenced to its source publication, and an annex listing the names of the source publications and their releases dates is included. All entries were reviewed for punctuation, grammar, and clarity, as well as accuracy, and reworded if such was considered warranted. The purpose of this dictionary is to promote the uniform use of terms, definitions, abbreviations, and symbols throughout the solid state industry Committee(s): JC-10 Free download.
