期刊High temperature electron cyclotron resonance etching of GaN, InN, and AlN
《Applied Physics Letters》R. J. Shul[1];S. P. Kilcoyne[1];M. Hagerott Crawford[1];J. E. Parmeter[1];C. B. Vartuli[2];C. R. Abernathy[2];and S. J. Pearton[2]
Electron cyclotron resonance etch rates for GaN, InN, and AlN are reported as a function of temperature for Cl2/H2/CH4/Ar and Cl2/H2/Ar plasmas. Using Cl2/H2/CH4/Ar plasma chemistry, GaN etch rates remain relatively c...显示全部
