A savory, shelf-stable, particulate, meltable, food-grade plasticized composition is disclosed, having a water activity Aw of 0. The electroless Ni plated bumps are arranged in at least two rows in parallel with the two sides of the semiconductor chip, opposing each other. Also disclosed are compositions and methods for covalently immobilizing oligonucleotides and other biological molecules to glass and plastic surfaces. The extension has a hexagonal shaped shaft section and a retaining section. The insulation pattern insulates the first flexible electrode and the second flexible electrode from each other, and exposes upper and lower surfaces of the first flexible electrode and the second flexible electrode which are parallel to the second substrate, by covering portions of the first flexible electrode and the second flexible electrode.
