    Abstract: This disclosure describes systems, methods, and apparatus for operating a plasma processing chamber. In particular, a periodic voltage function combined with an ion current compensation can be provided as a bias to a substrate support as a modified periodic voltage function. This in turn effects a DC bias on the surface of the substrate that controls an ion energy of ions incident on a surface of the substrate. A peak-to-peak voltage of the periodic voltage function can control the ion energy, while the ion current compensation can control a width of an ion energy distribution function of the ions. Measuring the modified periodic voltage function can provide a means to calculate an ion current in the plasma and a sheath capacitance of the plasma sheath. The ion energy distribution function can be tailored and multiple ion energy peaks can be generated, both via control of the modified periodic voltage function.

    Abstract: An ion implantation system and method are disclosed in which glitches in voltage are minimized by modifications to the power system of the implanter. These power supply modifications include faster response time, output filtering, improved glitch detection and removal of voltage blanking. By minimizing glitches, it is possible to produce solar cells with acceptable dose uniformity without having to pause the scan each time a voltage glitch is detected. For example, by shortening the duration of a voltage to about 20-40 milliseconds, dose uniformity within about 3% can be maintained.

    Abstract: The present invention is directed to a switch circuit and method to quickly enable or disable the ion beam to a wafer within an ion implantation system. The beam control technique may be applied to wafer doping repaint and duty factor reduction. The circuit and method may be used to quench an arc that may form between high voltage electrodes associated with an ion source to shorten the duration of the arc and mitigate non-uniform ion implantations. The circuit and method facilitates repainting the ion beam over areas where an arc was detected to recover dose loss during such arcing. A high voltage high speed switching circuit is added between each high voltage supply and its respective electrode to quickly extinguish the arc to minimize disruption of the ion beam. The high voltage switch is controlled by a trigger circuit which detects voltage or current changes to each electrode. Protection circuits for the HV switch absorb energy from reactive components and clamp any overvoltages.

    Abstract: An electron beam apparatus having an electron analyzer is achieved which can control the illumination lens system by feedback without adversely affecting the imaging action even if a specimen is positioned within the magnetic field of the objective lens. The apparatus has an energy shift control module for controlling energy shift. On receiving instructions about setting of energy shift from the CPU, the control module issues an instruction for shifting the accelerating voltage to a specified value to an accelerating-voltage control module. The control module also sends information about the energy shift to an energy shift feedback control module, which calculates the feedback value and supplies information about corrections of lenses and deflection coils to a TEM optics control module. The feedback value is multiplied by a corrective coefficient that can be calibrated.
