Identification of direct-marked 2D codes on solar wafers

Directly marking each wafer provides traceability, and thus the feedback for process improvement. The code, however, must be as small as possible to not degrade performance. As the wafer progresses through manufacturing, this code must be read in ever more difficult optical environments. The Lector620 was precisely developed for such tough applications.
