Patent ID: 7998884

Claim:
A method for forming a light emitting device using a silicon (Si) nanocrystalline Si insulating film, the method comprising: providing a bottom electrode selected from a group consisting of a doped semiconductor and metal; using a high density plasma-enhanced chemical vapor deposition (HDPECVD) process, depositing a Si insulator film overlying the bottom electrode, having a thickness in a range of 30 to 200 nanometers (nm) and consisting of SiOx, where X is less than 2; annealing the Si insulating film; forming Si nanocrystals in the Si insulating film in response to the annealing; forming a transparent metal electrode overlying the Si nanocrystalline Si insulating film; wherein depositing the SiOx film includes: introducing silane (SiH 4 ) in a range of about 20 to 30 standard cubic centimeters (SCCM); introducing N 2 O in a range of about 25 to 35 SCCM: supplying power to a top electrode at a frequency in a range of 13.56 to 300 megahertz (MHz), and a power density in a range of about 1 to 20 watts per square centimeter (W/cm 2 ); and, supplying power to a bottom electrode at a frequency in a range of 50 kilohertz to 13.56 MHz, and a power density in a range of about 1 to 5 W/cm 2 .
