Abstract:
1. A circuit comprising: a program transistor comprising a first portion of a substrate; a control capacitor comprising a second portion of the substrate, the first and second portions of the substrate comprising material from multiple implantations; and an oxide over the first and second portions of the substrate and over a third portion of the substrate, the oxide thicker over the first and second portions of the substrate than over the third portion of the substrate; wherein the first portion of the substrate comprises material from a deep N-well (DNW) implantation, a high-energy N-well (HiNWell) implantation, a high-energy P-well (HiPWell) implantation, and a P-well implantation; and wherein the second portion of the substrate comprises material from the DNW implantation, the HiNWell implantation, the HiPWell implantation, the P-well implantation, and an N-well implantation.
