X-ray ablation

In another report, instead of direct x-ray ablation, an x-ray mask, which was 10-pm-thick Au on a Kapton film, was employed to ablate a PMMA wafer. Then the ablated PMMA wafer was developed. For sealing, a PMMA cover was first spin-coated with a 2-pm layer of poly(butyl methacrylate-co-methyl methacrylate) and then thermally bonded to the PMMA plate (120°C for 1 h) [200].
