A dielectric layer (e.g., an interpoly dielectric layer) is deposited over low and high voltage devices of a peripheral memory device. The dielectric behaves as an oxidation and wet oxide etch barrier. The dielectric prevents the devices from being stripped by a wet oxide etch that can result in the exposure of the silicon corners. The exposure of a silicon corner may increase thinning of a gate oxide at the field edge. This causes variability and unreliability in the device. The dielectric is not removed from a device until the device is ready for processing. That is, the dielectric remains on a device until the growing of a gate oxide on that device has begun. This reduces the exposure of the silicon corner. Hedges that result may be removed by exposing a trench in the field oxide at the hedge.
