A device separated from a wafer includes: a chip having a sidewall, which is provided by a dicing surface of the wafer in a case where the device is separated from the wafer; and a protection member disposed on the sidewall of the chip for protecting the chip from being contaminated by a dust from the dicing surface. In the device, the dicing surface of the wafer is covered with the protection member so that the chip is prevented from contaminated with the dust.
