    Abstract: Bei einem Verfahren zum Beschichten einer Oberfläche (1) eines Trägermaterials (2) mit Molekülen (5, 6), wobei die Moleküle (5, 6) aus einem Molekülvorrat (3, 4) in einen gasförmigen Zustand überführt und ionisiert werden, werden die elektrisch geladenen Moleküle (5, 6) auf dem Weg zu der Oberfläche (1) mindestens einem elektrischen und/oder magnetischen Feld ausgesetzt werden, das mindestens eine Feldkomponente senkrecht zu der gerichteten Bewegung der elektrisch geladenen Moleküle (5, 6) aufweist, um eine senkrecht zu der gerichteten Bewegung der elektrisch geladenen Moleküle (5, 6) gerichtete Kraftwirkung auf die elektrisch geladenen Moleküle (5, 6) auszuüben. Zwischen dem Molekülvorrat (3, 4) und der Oberfläche (1) wirkt eine elektrische und/oder magnetische Fokussiereinrichtung (8), beispielsweise ein Quadrupolfeld, auf die gerichtete Bewegung der elektrisch geladenen Moleküle (5, 6) ein. Zwischen dem Molekülvorrat (3, 4) und der Oberfläche (1) ist eine Blendenvorrichtung (12) so angeordnet, dass nur Moleküle (5, 6) mit einem vorgebbaren Massen-Ladungs-Verhältnis durch die Blendenvorrichtung (12) hindurch zur Oberfläche (1) gelangen. Mittels geeigneter elektrischer und/oder magnetischer Felder oder mittels zeitlich veränderbarer Blendeneinrichtungen (14) wird für vorgebbare Zeitdauern ein Auftreffen der elektrisch geladenen Moleküle (5, 6) auf der Oberfläche (1) verhindert. Dadurch wird die strukturierte Beschichtung der Oberfläche ermöglicht.

    Abstract: A system (200) and method for magnetically filtering an ion beam (210) during an ion implantation into a workpiece (228) is provided, wherein ions are emitted from an ion source (212) and accelerated the ions away from the ion source to form an ion beam. The ion beam is mass analyzed by a mass analyzer (214), wherein ions are selected. The ion beam is then decelerated via a decelerator (242) once the ion beam is mass-analyzed, and the ion beam is further magnetically filtered downstream of the deceleration. The magnetic filtering is provided by a quadrapole (quadrupole) magnetic energy filter (250), wherein a magnetic field is formed for intercepting the ions in the ion beam exiting the decelerator to selectively filter undesirable ions and fast neutrals (264).

    Abstract: An ion implantation system (600) having a dose cup (634) located near a final energy bend of a scanned or ribbon-like ion beam of a serial ion implanter for providing an accurate ion current measurement associated with the dose of a workpiece or wafer. The system comprises an ion implanter having an ion beam source for producing a ribbon-like ion beam (602). The system further comprises an AEF system configured to filter an energy of the ribbon-like ion beam by bending the beam at a final energy bend. The AEF system further comprises an AEF dose cup associated with the AEF system and configured to measure ion beam current, the cup located substantially immediately following the final energy bend. An end station (610) downstream of the AEF system is defined by a chamber wherein a workpiece is secured in place for movement relative to the ribbon-like ion beam for implantation of ions therein. The AEF dose cup is beneficially located up stream of the end station near the final energy bend mitigating pressure variations due to outgassing from implantation operations at the workpiece. Thus, the system provides accurate ion current measurement before such gases can produce substantial quantities of neutral particles in the ion beam, generally without the need for pressure compensation. Such dosimetry measurements may also be used to affect scan velocity to ensure uniform closed loop dose control in the presence of beam current changes from the ion source and outgassing from the workpiece.
