摘要： A magnetic scanning technique for sweeping an ion beam across an implantation target, such as a semiconductor wafer, by means of modulating the energy of a beam and directing it through an analyzer magnet, which effects a scanning motion of the beam of constant intensity, the wave form for the modulation being selected to take into account that the areal density of the ions in the scanned beam varies dependently with the amount of displacement of the beam from a reference point. An ion scan can be obtained in which the ions travel in parallel paths and enter the target at a constant desired angle throughout the scan. The technique is applicable to targets held stationary or rotated during implant. By employing predetermined modulation wave forms which are adapted to other parameters of the selected system, a desired scan distribution of ions can be obtained, for instance a uniform distribution in X and Y directions. As applied to a semiconductor wafer rotated on a disc past the ion beam, the technique solves the problem of compensating for the fact that the area of a ring on the spinning disc depends linearly on the radius of the ring. The technique makes use of the properties of ion beams in uniform magnetic fields to produce a radial dependence of the density of the ion beam on the wafer which precisely cancels the radial dependence of circumferential length as a function of radius. The magnetic scanning technique is well adapted for use with large wafers held on rotating discs and has advantages over the conventional techniques of either electrostatic or mechanical scanning. The technique is readily adapted to a variety of other wafer transport systems including rotating conveyors and linear transports.

摘要： Apparatus for accurately measuring the charge distribution, and hence the voltage, on a non-conducting workpiece during ion bombardment. The invention is based on the principal that the charge on the surface of the workpiece induces equal and opposite charge on the surface of an isolated proof plane conductor placed in front of it. A workpiece is moved at a known speed in front of the proof plane, whose dimensions are small compared to the workpiece. The measurement of the time distribution of the induced charge on the proof plane is a measure of the spatial distribution of the charge on the bombarded workpiece. The proof plane surface is isolated from currents which might flow directly to its surface. The invention has utility for several purposes important to the semiconductor industry: monitoring the surface voltage distribution on a given workpiece during ion bombardment; certification to the device user that the workpiece was implanted under specified values or limits of surface voltage distribution; control of the surface charge distribution on the workpiece through the feedback of the charge-measurement signal to a device which compensates the charge on the workpiece.

摘要： Scanning, as of ion beams, in which two radially aligned devices, e.g. ion source and extraction electrode, are isolated from and accurately positioned with respect to one another, while the second device moves arcuately to produce a scanning effect. Advantageously, while one device, e.g. the ion source, is moved by a rotating shaft, the second device, e.g., the extraction electrode, moves on a curved track centered on the axis of the shaft. While the devices are disposed within respective parts of a vacuum chamber, a mechanical synchronizing mechanism, located outside of the chamber, moves the devices via seals. The specific mechanism shown comprises a driven lead screw, an insulating crank for driving a shaft on which an ion source is mounted, and an arcuate motion tracking device which transmits the motion of the insulating crank into the chamber for driving the extraction electrode upon a curved track.

摘要： A high throughput ion implantation system that rapidly and efficiently processes large quantities of flat panel displays. The ion implantation system has an ion source, an electrode assembly, a platform mounting a workpiece, and a ion beam measuring structure. The ion source in conjunction with the electrode assembly forms an ion beam in the shape of a ribbon beam. The ion beam is formed and directed such that a first portion of the ion beam treats the workpiece while a second portion of the ion beam is contemporaneously measured by the beam measuring structure. A controller obtains data from the beam measuring structure on the ion beam's parameters, and then generates control signals to the ion implantation system in response to the data.

摘要： An ion accelerator for use in an ion beam implanter. The accelerator forms milliampere beams of heavy ions such as boron and phosphorous in a configuration in which the terminal ion source is replaced by a neutral beam injector. The neutral beam is formed at ground by the conversion of a focused beam of positive ions to neutral ions in a charge exchange canal. The neutral beam so formed is stripped of one or more electrons in a gas or vapor filled canal in the high voltage terminal. A 180.degree. analyzing magnet located in the high voltage terminal analyzes and directs a selected charge state to an acceleration tube parallel to the neutral beam injection tube where the selected positive ions are accelerated to ground potential. To extend the energy range of the accelerator below the injection energy, a high voltage insulator is provided to insulate the ground end of the positive ion acceleration tube permitting the acceleration tube and terminal to be uniformly biased at a negative voltage to decelerate the beam to very low energies at a location close to the point of use. An accelerator assembly includes a 90.degree. analyzing magnet in the high voltage terminal.

摘要： A system and method for conductively and/or convectively transferring heat away from a workpiece that has been processed by a processing system, such as an ion implantation system. The conductive transfer of heat from the workpiece is effectuated by disposing the workpiece in relatively close proximity with a floor of a loadlock, which is maintained at a relatively cool temperature. The chamber pressure is disposed at a selected pressure by a pressure regulator and a vacuum pressure is applied to the backside of the workpiece closest to draw the workpiece into contact with the chamber floor, thereby effecting heat transfer from the workpiece to the cooling surface.

摘要： An ion implantation system that rapidly and efficiently processes large quantities of workpieces, such as flat panel displays. The ion implantation system includes a high vacuum process chamber that mounts an ion source, a single workpiece translating stage, and a loadlock. The single workpiece handling assembly mounted within the process chamber both removes the workpiece from the loadlock and supports the workpiece during implantation by the ion beam generated by the ion source. The process chamber is in selective fluid communication with a loadlock assembly, which in turn is mechanically integrated with a workpiece loading or end station. Additionally, the workpiece handling assembly includes a translation stage or element for translating the workpiece in a linear scanning direction during implantation. This linear scanning direction extends along a path transverse or orthogonal to the horizontal longitudinal axis of the implantation system. According to one practice, the scanning direction and the longitudinal axis form an angle therebetween that is less than or equal to about 85 degrees.

摘要： A machine which processes discrete wafer-form items in a chamber is provided with a slot-form channel along which the items move between points inside and outside the chamber, a lateral opening exposing the channel from its side, exposed walls of the channel defining a sealing margin directed toward that opening. A resilient sealing member is movable through the opening between an open position, in which the channel is not obstructed, and a sealing position, in which the sealing member resiliently engages the sealing margin. The machine shown is an ion implanter in which a beam of ions strikes the exposed item in the chamber. Features include a channel which makes an angle with the horizontal for gravity movement of the items; the sealing member serving as a stop to position an item along the length of the channel; and a plurality of openings and associated sealing members to provide locks on the sides of the chamber. The sealing member, preferably of cylindrical form, comprises an elongated resilient element disposed in the direction of the width of the slot and having a corresponding dimension greater than the thickness of the slot.
