A bottle cap includes a mouthpiece having a dispensing orifice, a collar which extends downward from the mouthpiece to engage the bottle, a cover connected to the collar by a hinge and movable between open position and closed position covering the orifice, and a tamper-evident strap connecting the closed cover to the collar. An embodiment is a method of forming a semiconductor device, the method including forming a first dielectric layer over a substrate, forming a first conductive layer in the first dielectric layer, and removing a first portion of the first conductive layer to form at least two conductive lines in the first dielectric layer, the at least two conductive lines being separated by a first spacing. Therefore, a demand of easily deleting such unnecessary data becomes stronger. The feedback may take the form of a tool tip related to the auxiliary control or a combination of auxiliary controls simultaneously touched.
