    摘要: A programmed, circuit-controlled digital micro-mirror device (DMD, 202) guides the laser light (201) to create on the surface (211) of an object (210) two-dimensional finely detailed symbolization sets, including bar codes, for a plurality of semiconductor devices (212). The laser light (224) changes a first optical reflectivity of full-field device surface regions to a second optical reflectivity different from and contrasting with the first reflectivity. The programming of the DMD may include time-dependent encrypted codes to shine the laser light onto portions of the two-dimensional surface regions during variable periods of time, creating shadow and three-dimensional effects.
