Abstract:
A housing having a woven appearance includes a substrate and a plurality of groove groups formed on the surface of the substrate. The groove groups define the woven appearance and are formed by etching. The housing may be made by using a film having a lightproof areas and a light-transmissible areas, the lightproof areas defining a woven appearance. The film is placed over a metal substrate having light-sensitive materials formed thereon and radiated with light. The light passing through the light-transmissible areas of the film solidifies the light-sensitive materials. After, removing the film from the substrate and cleaning un-solidified light-sensitive materials from the substrate to expose areas corresponding to the lightproof area, and an etching process is carried out to form the woven appearance on the exposed areas.
