Girls Day am FBH: 28.03.2019

Kleine Zwerge ganz groß

Winzige Halbleiter-Bauelemente wie Laser, Verstärker, Sendebausteine stecken in jedem Mobiltelefon, in der Supermarktkasse oder sorgen für Sicherheit im Auto. Sie helfen in der Medizin (Augenlaser, Zahnmedizin), bei der Materialbearbeitung (Schweißen, Schneiden, Beschriften) im Flugverkehr (Radar) und fliegen sogar in den Weltraum und treiben moderne Atomuhren.

Unsere Auszubildenden begleiten euch beim Ausflug in diese Mikrowelt. Wir zeigen euch, wie so ein winziges Bauteil aussieht (mit einem Mikroskop, weil die Strukturen viel kleiner sind als der Durchmesser eines menschlichen Haares). Ihr könnt bei praktischen Experimenten eure Fingerfertigkeit testen und erfahrt nebenbei viel Wissenswertes rund um unsere leistungsstarken Minilaser. Und ihr besichtigt die Speziallabore (Reinräume), in denen die Winzlinge hergestellt werden.

Seid ihr neugierig geworden? Probiert einmal aus wie vorsichtig man die kleinen Bauteile behandeln muss, wie es sich anfühlt einen Reinraumanzug zu tragen und fragt unseren Wissenschaftlerinnen und Mikrotechnologie-Azubis Löcher in den Bauch.
