R2R Laser Processing of Multi-Layer Vacuum deposited coatings on flexible substrates for 2D functional Devices

Roll-to-Roll (R2R) laser patterning of vacuum-deposited coatings on flexible substrates is
emerging as a versatile and efficient method for enabling advanced two-dimensional (2D)
functional devices. This method of patterning offers scalability, reliability, and cost-efficiency,
making it ideal for applications in electronics, optics, medical and energy systems. The
integration of laser processing techniques with vacuum deposited materials allows for high-
quality coatings that can be selectively patterned without the addition of masking elements or
chemical etching. Precision and uniform vacuum coated materials can be patterned and their
morphology can be controlled for specific applications. For example, wetting properties or
phase change functionalization can be performed. This approach streamlines product development by allowing for rapid prototyping, ease of process control, and fast changes to device design. Combining these technologies allows for a faster and more reliable method of
manufacturing flexible, high-performance 2D devices.
