  • Reduction of Reactive-Ion Etching-Induced Ge Surface

    2015-4-7An SF 6 /CF 4 cyclic reactive-ion etching (RIE) method is proposed to suppress the surface roughness and to optimize the morphology of Ge fin, aiming at the fabrication of superior Ge FinFETs for future CMOS technologies. The surface roughness of the Ge after RIE can be sufficiently reduced by introducing SF 6-O 2 etching steps into the CF 4Cited by: 4

  • Measurement of electron drift parameters for helium and

    1993-1-1Our restrictive ge- ometry is less sensitive to these effects, because it reduces tails of charge collection. The total length of the drift region was about 35 mm. The spacers between the stainless steel rings had a small opening for the laser beam allowing a typical step of 5 mm between two laser positions.
