WET ETCHING OF SILICON NITRIDE - microtechweb.com

2013-7-27 · Patterned nitride layers are also used as a mask for spatially selective silicon oxide growth, and as an etch mask when SiO2 masks cannot be used. One example of the latter situation is given by the anisotropic etching of silicon in KOH. The etching rate of SiO2 in KOH is nearly 1000 times slower than the etching rate of silicon, and in most ...

Structural and optical characterization of pure Si-rich ...

2013-1-16 · The specific dependence of the Si content on the structural and optical properties of O- and H-free Si-rich nitride (SiNx>1.33) thin films deposited by magnetron sputtering is investigated. A semiempirical relation between the composition and the refractive index was found. In the absence of Si-H, N-H, and Si-O vibration modes in the FTIR spectra, the transverse and longitudinal optical (TO-LO ...

Highly selective etching of silicon nitride over silicon ...

1999-11-4 · A highly selective dry etching process for the removal of silicon nitride (Si 3 N 4) layers from silicon and silicon dioxide (SiO 2) is described and its mechanism examined. This new process employs a remote O 2 /N 2 discharge with much smaller flows of CF 4 or NF 3 as a fluorine source as compared to conventional Si 3 N 4 removal processes.
