Conventional fabrication of sidewall oxide around an ONO-type memory cell stack usually produces Bird's Beak because prior to the fabrication, there is an exposed sidewall of the ONO-type memory cell stack that exposes side parts of a plurality of material layers respectively composed of different materials. Certain materials in the stack such as silicon nitrides are more difficult to oxidize than other materials in the stack such polysilicon. As a result oxidation does not proceed uniformly along the multi-layered height of the sidewall. The present disclosure shows how radical-based fabrication of sidewall dielectric can help to reduce the Bird's Beak formation. More specifically, it is indicated that short-lived oxidizing agents (e.g., atomic oxygen) are able to better oxidize difficult to oxidize materials such as silicon nitride and the it is indicated that the short-lived oxidizing agents alternatively or additionally do not diffuse as deeply through already oxidized layers of the sidewall such as silicon oxide layers. As a result, a more uniform sidewall dielectric can be fabricated with more uniform breakdown voltages along it height.

A telescopic charging handle incorporated into an upper receiver of an AR-15 type firearm includes a first stem portion integrally formed with a handle shaped head. A second stem portion terminates at a distal end in a projecting beak and is further telescopically engaged at a proximal end to the first stem portion.

A scalpel for performing complex surgeries, such as c-sections, is formed of a body that is preferably elongated and shaped and sized to fit ergonomically into the hands of surgeons. The body has surfaces that are joined to each other by smooth transition elements to insure that the body has no points or sharp edges that could cut or scratch the surgeon or the patient. The body is formed with a triangular notch formed of a beak and an extension. A surgical blade, preferably a standard off-the-shelf surgical blade, is imbedded in the body and the only portion of the blade that is accessible is a portion of its cutting edge spanning the notch. The scalpel is used by introducing the beak into a slit in the tissue with the blade portion facing the direction in which the cut is to be made. The body of the scalpel is then grasped firmly and advanced to make the cut. The initial incision can be made with the tip of the beak.

The invention provides a method of identifying day age of cephalopods through beaks and includes a method of grinding a beak longitudinal section and counting growth striation. The method mainly includes the steps of: extraction, cleaning, soaking, cutting, arrangement, resin embedding, cutting, immobilization on a glass slide, grinding and polishing, picture forming, and growth striation counting. In the method, the beak longitudinal section is ground respectively from the left and right sides to a core surface towards a central line. A prepared section is photographed by CCD to ensure that the growth striation can be read at any time in future.
