摘要:
A method of fabricating an electroluminescent device includes preparing a wafer and a doped-silicon oxide precursor solution. The doped-silicon oxide precursor solution is spin coated onto the wafer to form a doped-silicon oxide thin film on the wafer, which is baked at progressively increasing temperatures. The wafer is then rapidly thermally annealed, further annealed in a wet oxygen ambient atmosphere. A transparent top electrode is deposited on the doped-silicon oxide thin film, which is patterned, etched, and annealed. The doped-silicon oxide thin film and the wafer undergo a final annealing step to enhance electroluminescent properties.

A method is provided for forming a rare earth element-doped silicon oxide (SiO2) precursor with nanocrystalline (nc) Si particles. In one aspect the method comprises: mixing Si particles into a first organic solvent, forming a first solution with a first boiling point; filtering the first solution to remove large Si particles; mixing a second organic solvent having a second boiling point, higher than the first boiling point, to the filtered first solution; and, fractionally distilling, forming a second solution of nc Si particles. The Si particles are formed by immersing a Si wafer into a third solution including hydrofluoric (HF) acid and alcohol, applying an electric bias, and forming a porous Si layer overlying the Si wafer. Then, the Si particles are mixed into the organic solvent by depositing the Si wafer into the first organic solvent, and ultrasonically removing the porous Si layer from the Si wafer.

A method for densifying sol-gel films to form microlens structures includes preparing a sol-gel precursor, having at least one solvent therein. The sol-gel precursor is spin coated onto a wafer to form a sol-gel film thereon. The wafer and sol-gel film are hot plate baked at a temperature less than 200° C. to remove at least some of the solvent. The baked, wafer and spin-coated sol-gel film are treated with an oxygen plasma treatment to remove any remaining solvent and to densify the sol-gel film. The spin coating, hot plate baking and treating steps may be repeated as required. A microlens is formed from the densified sol-gel film.

Methods of forming hafnium oxide, zirconium oxide and nanolaminates of hafnium oxide and zirconium oxide are provided. These methods utilize atomic layer deposition techniques incorporating nitrate-based precursors, such as hafnium nitrate and zirconium nitrate. The use of these nitrate based precursors is well suited to forming high dielectric constant materials on hydrogen passivated silicon surfaces.
