[DeepSOIC] was trying to find one before he decided to make his own by hacking a more readily available enhancement-mode transistor. For those not intimately familiar with semiconductor physics ...

Intel Foundry unveiled new breakthroughs to help drive the semiconductor industry forward into the next decade and beyond.

A transistor that is normally closed (on), allowing current to pass, but is triggered to open (off) and impede current. Contrast with "enhancement mode," wherein the transistor is normally open ...
