Abstract

Eine Vorrichtung, die ein Array von Sensoren aufweist, das auf einem Substrat mit einer Halbleiteroberfläche aufgebaut oder in dieses eingebaut ist, und Mittel zum Isolieren jedes Sensorelementes gegenüber seinen Nachbarn werden geschaffen. In dem Fall, dass die Sensoren Ultraschall-Transducerelemente sind, wird eine akustische Isolierung in Gestalt von Gräben zwischen benachbarten Transducerelementen zum Verringern des akustischen Übersprechens geschaffen. Die Gräben können mit einem akustisch dämpfenden Material gefüllt sein. Zwischen benachbarten Transducerelementen wird zur Verringerung des elektrischen Übersprechens eine elektrische Isolierung in Gestalt von Halbleiterübergängen geschaffen. In einem Beispiel werden entgegengerichtete pn-Dioden durch Ionenimplantation in Zonen gebildet, die zwischen benachbarten Transducerelementen angeordnet sind. Diese Art der Isolierung kann einzeln oder zusammen angewandt werden.
