Abstract: Methods for removing an oxide film and for cleaning silicon-on-insulator structures are disclosed. The methods may involve immersing the silicon-on-insulator structure in a stripping bath to strip an oxide film from the surface of the silicon-on-insulator structure. The stripped silicon-on-insulator structure is immersed in an ozone bath comprising ozone. The ozone-treated silicon-on-insulator structure may be immersed in an SC-1 bath comprising ammonium hydroxide and hydrogen peroxide to clean the structure.

Abstract: The present disclosure relates to a dual-polarized phased array antenna and a dual-polarized phased array weather radar. According to the dual-polarized phased array antenna, a plurality of dual-polarized row feeds are arranged on a horizontal cylindrical support surface to form a dual-polarized antenna in a horizontal cylindrical shape. This allows two polarized signals in a horizontal direction and a vertical direction to be simultaneously received and transmitted, and ensures digital multi-beam signals with constant beam bandwidth, antenna gain, and dual polarization performance. The dual-polarized phased array weather radar provided in the present disclosure uses the formed dual-polarized microstrip patch antenna or a dual-polarized waveguide slot antenna in the horizontal cylindrical shape. This can ensure consistency of weather detected at different scan angles, and improve the accuracy of weather target 3D construction.
