A method of manufacturing a NAND flash memory device. Antimony dopant is implanted into exposed regions of the active device area of the semiconductor substrate to form at least one of drain and source extension junctions andor drain and source contact junctions. Various touch inputs are sensed through a touch screen in the mobile terminal, and the mobile terminal and method present user interfaces corresponding to the respective touch inputs. In further embodiments the cuff guard may further comprise a decorative device affixed to the body of the cuff guard. The device with spray-coated external core is smaller and easier to swallow than the similar device having a compression-coated external coat.
