VON ARDENNE provides Flash Lamp Annealing for Cost-Sensitive Industries

For large-area substrates, VON ARDENNE has developed a cost-efficient flash lamp annealing solution, which has been successfully demonstrated in architectural glass coating at substrate widths of up to 3.8 meters (Figure 1).  

For small-area substrates, like those used in the semiconductor industry, flash lamp annealing has already been successfully commercialized. However, for substrates with a width of more than 1.5 meters, current flash lamp annealing solutions are too expensive, because several flash lamp arrays have to be combined. This complex device assembly leads to a very high capital expenditure that is basically not affordable for companies in cost-sensitive industries. For large-area substrates, VON ARDENNE provides an annealing technology that is suited for substrates with a width of up to 3.8 meters.

For high productivity and large-area substrates, VON ARDENNE offers a unique flash lamp technology, with the following benefits: 

  • Increases productivity by minimizing cycle time
  • Enables outstanding electrical & optical properties
  • Very high homogeneity thanks to VON ARDENNE lamp array concept
  • Large-area R2R & S2S processing with ≤ 3.8 m lamp length
  • Effective machine design for cost-sensitive industries  

This technology could also be applied to other layer systems. At laboratory scale, the transmission and conductivity of transparent conductive layers have been improved significantly by flash lamp annealing.
