A system, apparatus, and method which enable microcomponents to be electrically coupled in a desirable manner are disclosed. Preferably, XRD peaks corresponding to the and planes of the MgO\u2014AlN solid solution measured with CuK\u03b1 radiation appear at 2\u03b8=42. Two bits in a page buffer stores a write target value for the corresponding memory cell. The registration request is rejected if the comparison does not match. A method of fabricating includes providing a shell configured from a rod to provide an open interior cavity, sealing and partially filling the cavity with a plug to form a chamber, then forming fluid passages between the cavity and an outer surface of the tip electrode, and providing a lumen through which fluid can enter the chamber and exit therefrom through the fluid passages.
