Publication number: 20250107114Abstract: The invention provides a metal oxide semiconductor (MOS) capacitor structure, which includes a counter-doping region in the channel region directly below the gate. 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.Type: ApplicationFiled: October 16, 2023Publication date: March 27, 2025Applicant: UNITED MICROELECTRONICS CORP.Inventors: Pin-Tseng Chen, Ling-Chun Chou, Kun-Hsien Lee
