    摘要: A system and method for controlling a dosage profile is disclosed. An embodiment comprises separating a wafer into components of a grid array and assigning each of the grid components a desired dosage profile based upon a test to compensate for topology differences between different regions of the wafer. The desired dosages are decomposed into directional dosage components and the directional dosage components are translated into scanning velocities of the ion beam for an ion implanter. The velocities may be fed into an ion implanter to control the wafer-to-beam velocities and, thereby, control the implantation.

    摘要: An ion implanter system has a movable wafer support for holding a semiconductor wafer and a beam source that generates a beam for implanting ions in the semiconductor wafer while the wafer is moving. A plurality of path segments are identified, through which the wafer support is to move to expose the semiconductor wafer to the ion beam. A first position and a second position are identified for each respective one of the plurality of path segments, such that, when the wafer is in each first position and each second position, a perimeter of the beam projected in a plane of the wafer is tangent to a perimeter of the wafer. The ion implanter is configured to automatically move the wafer along each of the plurality of path segments, starting at the respective first position on each respective path segment and stopping at the respective second position on the same segment, so as to expose the wafer to the beam for implanting ions in the wafer.

    摘要: The present disclosure provides for various advantageous methods and apparatus of controlling electron emission. One of the broader forms of the present disclosure involves an electron emission element, comprising an electron emitter including an electron emission region disposed between a gate electrode and a cathode electrode. An anode is disposed above the electron emission region, and a voltage set is disposed above the anode. A first voltage applied between the gate electrode and the cathode electrode controls a quantity of electrons generated from the electron emission region. A second voltage applied to the anode extracts generated electrons. A third voltage applied to the voltage set controls a direction of electrons extracted through the anode.
