Patterning of dielectric films and pattern formation on film substrates are also possible!
"Photo etching processing," also known as photolithography processing, is a fine processing technique. It is possible to pattern not only metal films (such as chromium Cr, aluminum Al, and copper Cu) but also dielectric films like AR coatings and IR cut coatings. We manufacture calibration charts, reticles, memory, resolution charts, soft focus filters, and cross filters for photography. 【Features】 ■ Capable of handling up to 200mm ■ Provides high-precision patterning despite the disadvantages of wet etching in processing accuracy ■ Excellent cost performance and short delivery times ■ Capable of patterning dielectric films and forming patterns on film substrates *For more details, please download the PDF or feel free to contact us.
