This paper attempts to present a complete collection of semiconductor
devices. A total of 67 ''major'' devices have been identified, togethe
r with about 110 device variations which are considered to be ''relate
d'' devices to the former. These devices are organized into groups and
subgroups for a better overview, and the justification for such class
ification is discussed. After the list is presented, the author offers
