The present invention discloses user interface for creating a dynamic computing environment using allocateable resources. A second passivation layer is formed over the integrated circuit including over the fuse structure, and then patterned to open a window through the second passivation layer at a location over the fuse structure, with the window fully landed by the underlying passivation layer. A leaf spring acts between the second rod element and the reaction member for pushing the second rod element away from the intermediate element.
