Abstract: Various embodiments of the present application are directed to an integrated circuit (IC) comprising a floating gate test device with a cell-like top layout, as well as a method for forming the IC. In some embodiments, the IC comprises a semiconductor substrate and the floating gate test device. The floating gate test device is on the semiconductor substrate, and comprises a floating gate electrode and a control gate electrode overlying the floating gate electrode. The floating gate electrode and the control gate electrode partially define an array of islands, and further partially define a plurality of bridges interconnecting the islands. The islands and the bridges define the cell-like top layout and may, for example, prevent process-induced damage to the floating gate test device.
