The Heidelberg Instruments DWL-66 is a tool for mask making and for direct patterning of wafers by the use of a HeCd laser. Precise control of the laser head and alignment produces 800-nm resolution lithography. The DWL 66 is an extremely high-resolution imaging system where over half a million dpi is achieved using a 40-nm writeable address grid for exposing chrome plates or wafers.
