Claims (4)
- a) einer Vielzahl von nebeneinander angeordneten Elementen (1-2 bis 1-n), von denen jedes einfallende Röntgenstrahlen in Lichtstrahlen umsetzt und eine Lichtaustrittsfläche aufweist, aus der die Lichtstrahlen austreten,
- b) einer in einem Halbleitersubstrat von einem ersten Leitungstyp befindlichen Halbleiterstruktur (3), an der die Elemente befestigt sind und die eine Vielzahl von Halbleiter-Lichtdetektorzonen (12-1 bis 12-n) aufweist, die in einer Oberfläche des Halbleitersubstrats (8) ausgebildet sind, um aus der Lichtaustrittsfläche austretende Lichtstrahlen zu empfangen und in ein elektrisches Signal umzusetzen, wobei die Halbleiter-Lichtdetektorzonen (12-1 bis 12-n) entsprechend der Anordnung der Elemente (1-2 bis 1-n) voneinander beabstandete, in der Oberfläche des Halbleitersubstrats (8) ausgebildete erste Zonen (9-1 bis 9-n) des entgegengesetzten zweiten Leitungstyps aufweisen,
- c) einer ersten Elektrodenanordnung (5), die auf den ersten Zonen ausgebildet ist und dazu dient, ein elektrisches Signal von der Vielzahl von Halbleiter-Lichtdetektorzonen (12-1 bis 12-n) auszugeben, und
- d) einer Vielzahl von Kanalstopperzonen (10-1 bis 10-n), die jeweils in einer Zwischenzone der Oberfläche zwischen benachbarten Halbleiter-Lichtdetektorzonen (12-1 bis 12-n) ausgebildet sind, dadurch gekennzeichnet, daß
- e) die Kanalstopperzonen dazu dienen, ein elektrisches Signal abzuleiten, das erzeugt wird durch Lichtstrahlen, die auf die Zwischenzone der Oberfläche zwischen benachbarten Halbleiter-Lichtdetektorzonen fällt, daß dazu weiterhin eine zweite Elektrodenanordnung (6) auf den Kanalstopperzonen ausgebildet ist, die, um Signalanteile von den Kanalstopperzonen (10-1 bis 10-n) abzuleiten, mit einem Potential beaufschlagt wird, und daß
- f) die Kanalstopperzonen (10-1 bis 10-n) jeweils gebildet sind durch eine zweite Zone des zweiten Leitungstyps, welche in der Oberfläche des Halbleitersubstrats (8) zwischen den ersten Zonen (9-1 bis 9-n) des zweiten Leitungstyps ausgebildet sind.
