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.

摘要： 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.

摘要： A superlattice nanocrystal Si—SiO2 electroluminescence (EL) device and fabrication method have been provided. The method comprises: providing a Si substrate; forming an initial SiO2 layer overlying the Si substrate; forming an initial polysilicon layer overlying the initial SiO2 layer; forming SiO2 layer overlying the initial polysilicon layer; repeating the polysilicon and SiO2 layer formation, forming a superlattice; doping the superlattice with a rare earth element; depositing an electrode overlying the doped superlattice; and, forming an EL device. In one aspect, the polysilicon layers are formed by using a chemical vapor deposition (CVD) process to deposit an amorphous silicon layer, and annealing. Alternately, a DC-sputtering process deposits each amorphous silicon layer, and following the forming of the superlattice, polysilicon is formed by annealing the amorphous silicon layers. Silicon dioxide can be formed by either thermal annealing or by deposition using a DC-sputtering process.
