Abstract

Die Erfindung betrifft einen Gasverteiler mit einer Gaszuleitung (2), die mehreren Gasableitungen (3, 3', 3'') strömungsverbindet. Ein in die Gaszuleitung (2) eingespeister erster Massenfluss eines Gases wird derart auf die mehreren Gasableitungen (3, 3', 3'') aufgeteilt, dass durch zumindest zwei der Gasableitungen (3, 3', 3'') jeweils ein zweiter Massenfluss des Gases fließt. Um sicherzustellen, dass sich das Massenflussverhältnis bei einer Änderung eines Totaldrucks nicht ändert, besitzen die Gasableitungen (3, 3', 3'') Drosselelemente (4, 4', 4''), wobei die Drosselelemente (4, 4', 4'') ein oder mehrere untereinander gleichgestaltete Drosselkanäle (5) aufweisen, deren Durchflussfläche kleiner ist als die Durchflussfläche der zugeordneten Gasableitung (3, 3', 3''). Des Weiteren betrifft die Erfindung einen CVD-Reaktor (10) sowie ein Verfahren zum Einspeisen von Spülgasen in einen CVD-Reaktor (10).
