Abstract: A method of forming circuitry components includes forming a stack of horizontally extending and vertically overlapping features. The features extend horizontally though a primary portion of the stack with at least some of the features extending farther in the horizontal direction in an end portion. Operative structures are formed vertically through the features in the primary portion and dummy structures are formed vertically through the features in the end portion. Openings are formed through the features to form horizontally elongated and vertically overlapping lines from material of the features. The lines individually extend laterally about sides of vertically extending portions of both the operative structures and the dummy structures. Sacrificial material that is elevationally between the lines is at least partially removed in the primary and end portions laterally between the openings. Other aspects and implementations are disclosed.

Abstract: A meter base surge suppression system is mountable on a meter mounting panel and is adapted to receive and hold a conventional electric meter. The surge suppression system includes a base plate having a plurality of openings through which contact prongs may be inserted, and an electrical contact element disposed about one of the openings for making electrical contact with a prong inserted through the opening. A surge suppression device is disposed on an upper side of the base plate and is coupled between the contact element and ground potential. A receiving plate is mountable on the base plate and is adapted to receive and hold a conventional electric meter. The receiving plate includes a plurality of buss elements which extend downwardly through the receiving plate and through the openings in the base plate to engage and be received into prong receptacles of a meter mounting panel on which the urge suppression system is mounted.
