Abstract: In forming a punch-through stopper region in a fin field effect transistor (finFET) device, a substrate may be etched to form a pair of trenches that define a fin structure. A portion of a first dose of ions may be implanted into the substrate through a bottom wall of each trench to form a pair of first dopant regions that at least partially extend under a channel region of the fin structure. The substrate at the bottom wall of each trench may be etched to increase a depth of each trench. Etching the substrate at the bottom wall of each trench may remove a portion of each first dopant region under each trench. A remaining portion of the pair of first dopant regions under the fin structure may at least partially define the punch-through stopper region of the finFET device.

Abstract: A gas mixture method and apparatus of prolonging lifetime of an ion source for generating an ion beam particularly an ion beam containing carbon is proposed here. By mixing the dopant gas and the minor gas together to generate an ion beam, undesired reaction between the gas species and the ion source can be mitigated and thus lifetime of the ion source can be prolonged. Accordingly, quality of ion beam can be maintained.

Abstract: The time-averaged ion beam profile of an ion beam for implanting ions on a work piece may be smoothed to reduce noise, spikes, peaks, and the like and to improve dosage uniformity. Auxiliary magnetic field devices, such as electromagnets, may be located along an ion beam path and may be driven by periodic signals to generate a fluctuating magnetic field to smooth the ion beam profile (i.e., beam current density profile). The auxiliary magnetic field devices may be positioned outside the width and height of the ion beam, and may generate a non-uniform fluctuating magnetic field that may be strongest near the center of the ion beam where the highest concentration of ions may be positioned. The fluctuating magnetic field may cause the beam profile shape to change continuously, thereby averaging out noise over time.

Abstract: A method for an ion implantation is provided. First, a non-parallel ion beam is provided. Thereafter, a relative motion between a workpiece and the non-parallel ion beam, so as to enable each region of the workpiece to be implanted by different portions of the non-parallel ion beam successively. Particularly, when at least one three-dimensional structure is located on the upper surface of the workpiece, both the top surface and the side surface of the three-dimensional structure may be implanted properly by the non-parallel ion beam when the workpiece is moved across the non-parallel ion beam one and only one times. Herein, the non-parallel ion beam can be a divergent ion beam or a convergent ion beam (both may be viewed as the integrated divergent beam), also can be generated directly from an ion source or is modified from a parallel ion beam, a divergent ion beam or a convergent ion beam.

Abstract: Ion implantation systems and processes are disclosed. An exemplary ion implantation system may include an ion source, an extraction manipulator, a magnetic analyzer, and an electrode assembly. The extraction manipulator may be configured to generate an ion beam by extracting ions from the ion source. A cross-section of the generated ion beam may have a long dimension and a short dimension orthogonal to the long dimension of the ion beam. The magnetic analyzer may be configured to focus the ion beam in an x-direction parallel to the short dimension of the ion beam. The electrode assembly may be configured to accelerate or decelerate the ion beam. One or more entrance electrodes of the electrode assembly may define a first opening and the electrode assembly may be positioned relative to the magnetic analyzer such that the ion beam converges in the x-direction as the ion beam enters through the first opening.

Abstract: In an exemplary process for lower dose rate ion implantation of a work piece, an ion beam may be generated using an ion source and an extraction manipulator. The extraction manipulator may be positioned at a gap distance from an exit aperture of the ion source. A current of the ion beam exiting the extraction manipulator may be maximized when the extraction manipulator is positioned at an optimal gap distance from the exit aperture. The gap distance at which the extraction manipulator is positioned from the exit aperture may differ from the optimal gap distance by at least 10 percent. A first potential may be applied to a first set of electrodes. An x-dimension of the ion beam may increase as the ion beam passes through the first set of electrodes. The work piece may be positioned in the ion beam to implant ions into the work piece.

Abstract: A deceleration apparatus capable of decelerating a short spot beam or a tall ribbon beam is disclosed. In either case, effects tending to degrade the shape of the beam profile are controlled. Caps to shield the ion beam from external potentials are provided. Electrodes whose position and potentials are adjustable are provided, on opposite sides of the beam, to ensure that the shape of the decelerating and deflecting electric fields does not significantly deviate from the optimum shape, even in the presence of the significant space-charge of high current low-energy beams of heavy ions.
