    摘要: Liner elements to protect the ion source housing and also increase the power efficiency of the ion source are disclosed. Two liner elements, preferably constructed from tungsten, are inserted into the ion source chamber, one placed against each of the two sidewalls. These inserts are electrically biased so as to induce an electrical field that is perpendicular to the applied magnetic field. Such an arrangement has been unexpectedly found to increase the life of not only the ion chamber housing, but also the indirectly heated cathode (IHC) and the repeller. In addition, the use of these biased liner elements also improved the power efficiency of the ion source; allowing more ions to be generated at a given power level, or an equal number of ions to be generated at a lower power level.

    摘要: An non-Faraday ion dose measurement device is positioned within a plasma process chamber and includes a sensor located above a workpiece within the chamber. The sensor is configured to detect the number of secondary electrons emitted from a surface of the workpiece exposed to a plasma implantation process. The sensor outputs a current signal proportional to the detected secondary electrons. A current circuit subtracts the detected secondary current generated from the sensor and subtracts it from a bias current supplied to the workpiece within the chamber. The difference between the currents provides a measurement of the ion dose current calculated in situ and during the implantation process.

    摘要: An apparatus is provided for handling workpieces, such as semiconductor wafers, during semiconductor processing. The apparatus includes a wafer platen having a plurality of channels each extending from a top surface to a bottom surface of the wafer platen, a plurality of lift pins in alignment with the channels, and a mechanism for engaging the lift pins in a loading position of the workpiece, a clamping position of the workpiece so that desired semiconductor processes may be performed to the workpiece, and a lift off position for removing the workpiece from the wafer platen after the semiconductor processes are completed. The mechanism places the lift pins below the surface of the wafer platen in the load position and then raises the lift pins to a first predetermined distance above the surface of the wafer platen in the clamp position such that the first predetermined distance allows the workpiece to be clamped to the wafer platen. Then, the mechanism places the lift pins at a second predetermined distance above the surface of the wafer platen in the lift off position such that a workpiece removing device, such as a robotic arm, may be positioned between the workpiece and the wafer platen without contacting either surface.

    摘要: A charged particle beam apparatus includes a charged particle beam source for directing a charged particle beam along a beam path in a downstream direction to a target, and a processing station that defines a target chamber. The processing station includes a chamber divider which divides the target chamber into upstream and downstream regions during charged particle beam processing of the target, the target being located in the downstream region. The divider has an aperture therethrough sized to permit passage of the ion beam to the target without substantial blockage and to limit backflow of gas into the upstream region of the chamber. The divider minimizes the beam volume which is exposed to extraneous species generated at the target and thereby reduces the probability of beam-altering collisions.

    摘要: The present invention discloses a system and method for generating gas cluster ion beams (GCIB) having very low metallic contaminants. Gas cluster ion beam systems are plagued by high metallic contamination, thereby affecting their utility in many applications. This contamination is caused by the use of thermionic sources, which impart contaminants and are also susceptible to short lifecycles due to their elevated operating temperatures. While earlier modifications have focused on isolating the filament from the source gas cluster as much as possible, the present invention represents a significant advancement by eliminating the thermionic source completely. In the preferred embodiment, an inductively coupled plasma and ionization region replaces the thermionic source and ionizer of the prior art. Through the use of RF or microwave frequency electromagnetic waves, plasma can be created in the absence of a filament, thereby eliminating a major contributor of metallic contaminants.
