Ich möchte in meinem Bild einen 3D-Effekt erzielen. Dies soll Elektronenstrahllithografie gefolgt von einem Lift-off-Prozess zeigen. Ich möchte ein kreuzförmiges Loch in die obere Schicht machen und es bis zur Hälfte mit einem grauen Material füllen. Wie erreiche ich dies mit Opazität und Schattierung?
Danke

BEARBEITEN
Ich konnte das gewünschte Ergebnis erzielen, wie in der Abbildung unten gezeigt. Aber als ich es tatsächlich in meine Haupt-Tex-Datei kopierte, verhielt es sich seltsam. Es zeigte das auf der Folie erscheinende Material in weißer Farbe über vorhandenen Folien an. Ich habe es \setbeamercoveredin einer meiner Folien in meiner Haupt-Tex-Datei verwendet. Wenn ich diese Folie entferne, funktioniert es einwandfrei, aber wenn ich sie einfüge, verursacht es das Problem, wie unten gezeigt.
Funktionierende Lösung in separater Textdatei.
Beim Kopieren in den Haupttext wird folgende Ausgabe ausgegeben:
BEARBEITEN
Ich habe es mit dem Befehl \setbeamercovered{invisible} gelöst.
