Between the deep ion well and the counter-doping region is a semiconductor region. The doping concentration of the semiconductor region is lower than that of the deep ion well. The P-type well ion implantation processes in the active region of the device can be omitted, so the production cost is lower, and the dosage of the counter-doping region can be reduced, which improves the time-dependent dielectric collapse (TDDB) issue.
