Abstract: The present invention discloses a mark antenna used for receiving and transmitting a wireless signal. The mark antenna comprises a ground point, a feed point and a radiation part connecting to the ground point and the feed point, and particularly the radiation part is an identification mark, such that the appearance of the radiation part can provide identification information. With the light, thin, short and compact design concept, the mark antenna can be exposed to prevent the antenna from being compressed due to the small disposed area and overcome the difficulty of designing the antenna or a poor communication quality caused by the low performance of the antenna. In the present invention, the antenna is designed as a logo directly, such that the antenna can achieve the functions of identifying the appearance as well as transmitting and receiving the wireless signals.

Abstract: A method for maintaining a smooth surface of crystallizable material is disclosed. First, a substrate is provided. A target material layer is then formed on the substrate, with the target material being a crystallizable material. A protecting layer is subsequently formed on the target material layer. Next, an annealing treatment is implemented, with the surface of the target material layer, facing the protecting layer, being maintained in its original smooth state by the pressure and/or adhesion of the protecting layer. Finally, the protecting layer is removed to leave an open and smooth surface of the processed crystallizable material.
