Claim Text:
1. A method for treating a semiconductor surface of a semiconductor workpiece, comprising: directing an electron beam into a processing zone of a chamber containing said semiconductor workpiece, said electron beam propagating through said processing zone; introducing into said chamber a process gas comprising at least one of: (a) a cleaning species precursor, (b) a passivation species precursor, (c) an oxide reduction species precursor, whereby to generate a plasma while directly exposing said semiconductor surface to said plasma, and maintaining a plasma ion energy level of said plasma below a bonding energy of a material of said surface; forming in said surface at least one of: (a) N-MOS regions comprising group III-V compound semiconductor materials, (b) P-MOS regions comprising Ge or Ge-containing materials, wherein said forming in said surface at least N-MOS regions comprises:
