  • Publication number: 20220393101
    Abstract: Various embodiments of the present disclosure are directed towards an integrated circuit (IC) chip comprising a memory cell with a sidewall spacer, and/or an etch stop layer, doped to reduce charge accumulation at an interface between the sidewall spacer and the etch stop layer. The memory cell comprises a bottom electrode, a data storage element overlying the bottom electrode, and a top electrode overlying the data storage element. The sidewall spacer overlies the bottom electrode on a common sidewall formed by the data storage element and the top electrode, and the etch stop layer lines the sidewall spacer. The sidewall spacer and the etch stop layer directly contact at the interface and form an electric dipole at the interface. The doping to reduce charge accumulation reduces an electric field produced by the electric dipole, thereby reducing the effect of the electric field on the memory cell.
