    摘要: An ion implantation method is disclosed in this invention. The disclosed method is for implanting a target wafer with ions extracted from an ion source traveling along an original ion beam path. The method includes steps of a) employing a set of deceleration electrodes disposed along the original ion beam path before the target wafer for decelerating and deflecting the ion beam to the target wafer; and b) employing a charged particle deflecting means disposed between the ion source and the set of deceleration electrodes for deflecting the ion beam away from original ion beam path and projecting to the set of electrodes with an incident angle for the set of electrodes to deflect the ion beam back to the original ion beam path for implanting the target wafer.

    摘要: To select a scan distance to be used in scanning a wafer with an implant beam, a dose distribution along a first direction is calculated based on size or intensity of the implant beam and a scan distance. The scan distance is the distance measured in the first direction between a first path and a final path of the implant beam scanning the wafer along a second direction in multiple paths. A relative velocity profile along the second direction is determined based on the dose distribution. Dose uniformity on the wafer is calculated based on the wafer being scanned using the relative velocity profile and the determined dose distribution. The scan distance is adjusted and the preceding steps are repeated until the calculated dose uniformity meets one or more uniformity criteria.

    摘要: A method to rotate individual pad of a batch disk to an implant angle and lock them in place, with the pad surface having conical or near conical surface to minimize the implant angle variation across a wafer on the pad for both tilt angle and twist angle, at large tilt angle implant. The implanter includes a disk with multiple attached pads that can hold substrates securely when the hub is at rest or rotates. The disk rotates around its spin axis, which moves laterally at a programmed speed profile so that all substrates on the hub can get evenly touched by the fixed ion beam. The pad rotation axis is at an angle with the disk spin axis, and the angle is preferable 90 degrees. The nominal of the pad surface is at an angle, i.e., a tilt angle, relative to the incident ion beam. A rotation mechanism is applied to each individual pad to rotate the pad to the desired tilt angle. A locking mechanism is applied to each individual pad assembly to lock the pad at the desired tilt angle with minimum angle variation under high centrifugal force during fast disk spin. The locking mechanism includes: a) add brake to the rotation mechanism in the pad assembly so that the pad cannot rotate due to mechanical friction force or lock-key. B) use motor to hold the pad assembly. The sum of the friction torque and the motor holding torque should be larger than the centrifugal torque. A torque balancing mechanism is applied to pad mechanical design to minimize the total pad rotation torque under centrifugal force during fast disk spin by adding mass to counter balance the original wafer pad mass.

    摘要: An ion implantation method for reducing energy contamination in low energy beams is disclosed in this invention. The ion implantation method requires the use of a target chamber for containing a target for implantation in vacuum and an ion source chamber with an ion source for generating an ion beam. A means for conducting a mass analysis of the ion beam, such as an analyzer magnet, is also needed. The ion source chamber includes a beam deceleration optics that includes a beam deceleration means for decelerating the ion beam for producing a low energy ion beam. The beam deceleration optics further includes a beam steering means for generating an electrostatic field for steering the ion beam to a targeted ion-beam direction and separating neutralized particles from the ion beam by allowing the neutralized particles to transmit in a neutralized-particle direction slightly different from the targeted ion-beam direction. The ion beam steering means further includes a beam stopper for blocking said neutralized particles from reaching said target of implantation that minimizes energy contamination from high energy neutralized particles.
