Selective Deposition & Patterning

The extrusion coating process is typically employed to deposit the process material over essentially the entire substrate, with the exception of a small uncoated area (typically about 5-10mm wide) that is left around the perimeter of the substrate. For many customers, this full area coating meets their process objectives. However, for certain applications, it is desirable to have certain areas coated with the process material, while other areas are free of this material. Traditionally, this is achieved in the industry by some type of patterned removal process, which uses a number of additional process steps and materials to achieve the resulting pattern (at considerable cost). For micro patterning, such as the formation of microscopic features and circuits, the traditional methods of photolithography still dominate the industry, despite their intrinsic cost.

There is also a need for less precise patterning (or “macro patterning”) of the coated areas, as an alternative to expensive photolithographic methods and primitive masking or laser ablation methods. To address that requirement, nTact has developed lower cost Macro Patterning technologies that have the potential to revolutionize certain processes in the Display, PV and SSL industries.
