Infrascreen is committed to the vision of everyone having access to healthy and sustainable fruits and vegetables as well as reaching carbon neutrality. It proposes “smart materials” towards an enhanced climate control in green house. Infrascreen produces low-e film for greenhouses; metallic nano-meshes are an alternative approach to obtain a low-emissivity surface to the more conventional dielectric-metal-dielectric coatings. Such low-e coatings are also used in windows. Here we present a collaboration Infrascreen-CSEM to develop a fabrication process (Figure 1) in the frame of 150 mm wafer technology. Grids of sub-μm metallic line widths have been fabricated on glass wafers (Figure 2, 3). The structures have been simulated and evaluated
Fourier transform infrared (FTIR) among other techniques (Figure 4).
