The method according to the invention and the apparatus (1) according to the invention advantageously permit apparatuses for the treatment of semiconductor substrates such as in particle implanters to be supplied with doping gas such as, for example, phosphine and/or arsine from adsorber-free gas cylinders (14). On account of the configuration of buffer hose (7) and shield hose (24), and also the corresponding coatings (25, 26), the admission of water vapour into the buffer hose (7) and thus also into the doping gas hose (6) can be reduced in comparison with solutions known from the prior art. The risk of corrosion for the equipment supplied with the doping gas thus decreases.

Abstract:
Verfahren zum Behandeln eines Halbleitersubstrats (2), bei dem ein Ionenstrahl (4) aus einem Dotiergas erzeugt und auf das Halbleitersubstrat (2) gelenkt wird, dadurch gekennzeichnet, dass das Dotiergas durch einen Kunststoffschlauch (6) einem Mittel (3) zum Erzeugen eines Ionenstrahls (4) zugeführt und dann ionisiert wird. Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung 1 erlauben in vorteilhafter Weise die Versorgung des Mittels 3 zum Erzeugen eines Ionenstrahls 4 mit einem Dotiergas aus üblichen Gasreservoiren 14 wie beispielsweise übliche Druckgasflaschen. Durch den erfindungsgemäßen Pufferschlauch 7 wird gewährleistet, dass kein Dotiergas in die Umgebung abgegeben werden kann. So erlaubt das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung 1 den einfachen Aufbau einer entsprechenden Ionenimplantationseinrichtung bei gleichzeitig möglicher Versorgung derselben mit Dotiergas, wobei ein Austritt von Dotiergas an die Umgebung weitestgehend ausgeschlossen ist.

The apparatus (1) according to the invention for regulating a process medium flow (2) to be fed to a process medium consumer (28), comprising a) a process medium path (3), by means of which a process medium source (27) can be connected to the process medium consumer (28), and b) a control gas path (4), by means of which a control gas pressure can be built up with a control gas, wherein the process medium path (3) comprises a pneumatic pressure regulator (5), the control input (6) of which is connected to the control gas path (4), wherein means (7) for regulating the control gas pressure are embodied, is distinguished by the fact that the means (7) for regulating the control gas pressure comprise a delivery valve (8) for connecting the control gas path (4) to a control gas pressure source (9) and a discharge valve (10) for decreasing pressure in the control gas path (4). The apparatus (1) according to the invention and the method according to the invention advantageously permit precise regulation of the process medium flow (2) from a process medium source (27) to a process medium consumer (28) using simple means.
