Highly-integrated low-mass solar sail

摘要: Low mass-per-unit-area plastic film, preferably polyimide, prepared by a process of controlled treating supply possibly with one surface reflectively coated, at microlithography workstation included photoablation optics. This treatment achieves significant removal material in selected pattern providing relative motion between untreated film and the workstation's optics while controlling film. The has quantity mass its removed photoablation, leaving tessellated ridges surrounding individual wells. resulting low-mass, rip-resistant retains general attributes large-area treated also reflective surface, on which amorphous silicon may be deposited. thereafter crystallized, utilizing same optics, used for fabrication microelectronics.
