We investigate the effect of cations with different valences on the chemical mechanical polishing(CMP)of silicon dioxide films.The removal rate and surface roughness of the silicon-dioxide-film post-CMP are checked fo...
We report the latest research development of vertical buffered electropolishing on its post-treatment procedure as well as the effects of several major post-treatment techniques for buffered electropolishing(BEP)proce...

Based on the large cross-section single-mode rib waveguide condition,the total internal reflection and the free-carrier plasma dispersion effect,a silicon-on-insulator(SOI)2×2 symmetric optical waveguide switch with ...
Mechanical polishing and subsequent thermal oxidation are the indispensable condition for rapid formation of a continuous and highly Cr-enriched layer on the surface of a Ni-Cr alldy.Direct observations of the Cr dist...
