Patent ID: 7902088

Claim:
A method for fabricating a high quantum efficiency silicon (Si) nanoparticle embedded SiO X N Y film for luminescence (electroluminescence—EL and photoluminescence—PL) applications, the method comprising: providing a bottom electrode; depositing a Si nanoparticle embedded non-stoichiometric SiO X N Y film, where (X+Y<2 and Y>0), overlying the bottom electrode, as follows: introducing a Si precursor and hydrogen; depositing a SiO X N Y film overlying the bottom electrode, using a high density (HD) plasma-enhanced chemical vapor deposition (PECVD) process; and, supplying power to a top electrode at a frequency in the range of 13.56 to 300 megahertz (MHz), and a power density of less than 5 watts per square centimeter (W/cm 2 ); annealing the Si nanoparticle embedded SiO X N Y film; and, forming an annealed Si nanoparticle embedded SiO X N Y film having an extinction coefficient (k) of less than about 0.001 as measured at 632 nanometers (nm), and a PL quantum efficiency (PLQE) of greater than 20%.
