A method and eFuse circuit for implementing enhanced security features using eFuses, such as disabling selected predefined test, debug, and mission security functions used in application-specific integrated circuits, and a design structure on which the subject circuit resides are provided. In preferred embodiments, the resin composition further comprises at least one member of the group consisting of polyphenylene ether-polyolefin copolymers, polystyrene-polyolefin copolymers, and polystyrene resins. The plunger rod includes at least one aperture in fluid communication with a hollow interior of the plunger rod. From there the slurry is sheared, dewatered, and dried, forming a finished fiberboard. The potential of each of the two sets of electrodes have a gradient based on the distance along a direction perpendicular to the plane of the particle collecting surface. The control depth reduces the precision of depth perception required to find the control.
