WebThe results showed that the sol-gel synthesis is a feasible alternative method for obtaining silica xerogel using ashes with high impurities contents, such as iron and aluminum oxide. Amorphous SiO2 nanoparticles with an average size of ~10 nm were obtained by controlling the main synthesis variables (pH, temperature and SiO2/H2O molar ratio). WebSemiconductor devices and methods of manufacturing the same are described. The methods form a 3D DRAM architecture that includes a semiconductor isolation bridge, eliminating a floating body effect. The method includes forming an epitaxial layer in a deep trench isolation opening and creating a semiconductor isolation bridge between adjacent …
