A method is presented for forming a semiconductor structure. The method includes forming a plurality of fins on a first region of the semiconductor substrate, forming a bi-polymer structure, selectively removing the first polymer of the bi-polymer structure and forming deep trenches in the semiconductor substrate resulting in pillars in a second region of the semiconductor structure. The method further includes selectively removing the second polymer of the bi-polymer structure, doping the pillars, and depositing a high-k metal gate (HKMG) over the first and second regions to form the MIS capacitor in the second region of the semiconductor substrate. |
