Bi-directional blocking voltage protection devices and methods of forming the same |
摘要 |
Bi-directional blocking voltage protection devices and methods of forming the same are disclosed. In one embodiment, a protection device includes an n-well and first and second p-wells disposed on opposite sides of the n-well. The first p-well includes a first P+ region and a first N+ region and the second p-well includes a second P+ region and second N+ region. The device further includes a third P+ region disposed along a boundary of the n-well and the first p-well and a fourth P+ region disposed along a boundary of the n-well and the second p-well. A first gate is disposed between the first N+ region and the third P+ region and a second gate is disposed between the second N+ region and the fourth P+ region. The device provides bi-directional blocking voltage protection during high energy stress events, including in applications operating at very low to medium swing voltages. |
