A pliers for forming orthodontic wires has opposing beaks with complementary wire-forming surfaces that include interfering portions. A hinge mechanism enables the beaks to open and close by rotating about an axis, and also allows a range of axial motion between the beaks sufficient to prevent interference between the wire-forming surfaces as the beaks are closed. By preventing such interference, novel over-bending capabilities can be achieved to form useful bending of low spring rate wire. A spring, such as a Belleville washer, exerts a biasing force parallel to the hinge axis to maintain alignment of the beaks, but allows the required range of axial motion between the beaks to prevent interference.

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.
