'[EE]:: 15 trillion dollar man.'

Not many individuals are attributed (rightly or no) with saving
society 15 Trillion dollars with their inventions .

One who is, is Jayant Baliga.
How many engineers have heard of him or know what his "great
development" was (amongst his 100 or so patents)?

     http://en.wikipedia.org/wiki/B._Jayant_Baliga

The relevant development is "obvious enough" in retrospect -  an "It
Steam Engines come Steam Engine time" event. Apparently not so obvious
prior to its 'invention'. A lot of people were active in the field in
parallel with JB being among the leaders in developing practical
implementations of the theoretical devices.


Along the way termed a

 - ‘V-groove MOSFET device with the drain region replaced by a p-type
Anode Region’
  - insulated gate rectifier (IGR)
 -  insulated-gate transistor (IGT)
 -  conductivity-modulated field-effect transistor (COMFET)
 -  "bipolar-mode MOSFET".
Nowadays, usually, IGBT.

Mostly known as the father of the IGBT, but as you point out, he invented many other useful technologies:
