摘要： An ion beam tuning method, system and program product for tuning an ion implanter system are disclosed. The invention obtains an ion beam profile of the ion beam by, for example, scanning the ion beam across a profiler that is within an implant chamber; and tunes the ion implanter system to maximize an estimated implant current based on the ion beam profile to simultaneously optimize total ion beam current and ion beam spot width, and maximize implant current. In addition, the tuning can also position the ion beam along a desired ion beam path based on the feedback of the spot beam center, which improves ion implanter system productivity and performance by reducing ion beam setup time and provides repeatable beam angle performance for each ion beam over many setups.

摘要： An apparatus and method are provided for optimizing ion implantation uniformity in a workpiece, such as a semiconductor wafer, which includes an ion beam generator for generating an ion beam, a beam scanning mechanism for diverging the ion beam and generating substantially parallel ion beam trajectories towards the workpiece, and an ion beam detector for measuring the ion beam current of the parallel ion beam trajectories as a function of the position of the ion beam detector. A uniformity controller filters the ion beam current measured by the ion beam detector to at least one predetermined resolution range and generates a uniformity signal to the beam scanning mechanism in response to the filtered ion beam current so that the workpiece is uniformly implanted. The uniformity controller determines a controllable frequency range for optimizing ion implantation uniformity control by making controllable frequencies observable and uncontrollable frequencies unobservable. As a result, the uniformity controller observes and controls spacially distributed components of the profiled beam current for optimizing the implantation of doses to the workpiece in a time and cost efficient manner.

摘要： Methods and apparatus are provided for adjusting the profile of a scanned ion beam. The spatial distribution of the unscanned ion beam is measured. The ion beam is scanned at an initial scan speed, and the beam profile of the scanned ion beam is measured. If the measured beam profile is not within specification, a scan speed correction that produces a desired profile correction is determined using a calculation which is based on the spatial distribution of the unscanned ion beam. The scan speed correction may be determined by convolving a candidate scan speed correction with the spatial distribution of the unscanned ion beam to produce a result and determining if the result is sufficiently close to the desired profile correction. A multi-dimensional search algorithm may be used to select the candidate scan speed correction. The ion beam is scanned at a corrected scan speed, which is based on the initial scan speed and the scan speed correction, to produce corrected beam profile.

摘要： Embodiments disclosed herein can introduce low amounts of gas in a liquid with fast response time and low variation in concentration. In one embodiment, a gas is directed into an inlet on a gas contacting side of a porous element of a contactor and a liquid is directed into an inlet on a liquid contacting side of the porous element of the contactor. The liquid contacting side and the gas contacting side are separated by the porous element and a housing. The gas is removed from an outlet on the gas contacting side of the porous element at a reduced pressure compared to the pressure of the gas flowing into the inlet of the contactor. A liquid containing a portion of the gas transferred into the liquid is removed from an outlet on the liquid contacting side of the porous element, producing a dilute bubble free solution.
