The hammer for breaking polycrystalline silicon is provided with a handle portion extending along a center axis and a head portion extending in a direction intersecting a direction of the center axis at the leading end of the handle portion. Flaps extend from lower sidewall edges and fold along fold lines to form a bottom. The method includes forming a superabrasive polycrystalline diamond compact by combining: a plurality of derivatized nanodiamond particles, a plurality of derivatized microdiamond particles having an average particle size greater than that of the derivatized nanodiamond particles, and a metal solvent-catalyst. The metal layer can provide one or more power planes within the substrate. In one embodiment, the mobile terminal includes the internal positioning system, a transceiver, and a mobile terminal position controller.
