摘要： A method of measuring ion dose in a plasma immersion ion implantation reactor during ion implantation of a selected species into a workpiece includes placing the workpiece on a pedestal in the reactor and feeding into the reactor a process gas comprising a species to be implanted into the workpiece, and then coupling RF plasma source power to a plasma in the reactor. It further includes coupling RF bias power to the workpiece by an RF bias power generator that is coupled to the workpiece through a bias feedpoint of the reactor and measuring RF current at the feedpoint to generate a current-related value, and then integrating the current-related over time to produce an ion implantation dose-related value.

摘要： A method of fabricating a silicon-on-insulator structure having a silicon surface layer in a semiconductor workpiece, is carried out by maintaining the workpiece at an elevated temperature and producing an oxygen-containing plasma in the chamber while applying a bias to the workpiece and setting the bias to a level corresponding to an implant depth in the workpiece below the silicon surface layer to which oxygen atoms are to be implanted, whereby to form an oxygen-implanted layer in the workpiece having an oxygen concentration distribution generally centered at the implant depth and having a finite oxygen concentration in the silicon surface layer. The oxygen concentration in the silicon surface layer is then reduced to permit epitaxial silicon deposition.
