Minimally invasive endoscopic and laparoscopic devices and methods for inverting and closing a diverticulum. A wafer is loaded on a susceptor and the susceptor includes at least one pocket whose bottom surface is inclined. In a preferred embodiment, the first and second MOS transistors are N-MOS transistors disposed in a common P-well and the drift region of the first MOS transistor further comprising a P-drift region.
